Wow.Wonderfull.Is it possible to connect a graf/equalizer on a av receiver?Is it going to boost and improve the sound quality?


you're not a fan of your mother in law eh?

Savan Panchal

I have same AVR - Marantz SR8012 and using 2 SVS Sb3000 subs - after using MultiEQ app - I get this one Null around 80-90 hZ - what would be the best way to fix or improve that to make it as flat as possible and I don't have much option to move my Subs? Any possibility of me showing you the curves that I got?

How dare you?

Could u do a video of how to measure properly a fulrange speaker with this mic?

David Raimundo

Is there a video tutorial on how to for dummies for REW?


Why is my sweep playing through my front towers instead of only my subs, am I missing something?

Texan Range

Still NO ONE does this THIS well!

Mark Mullen

I have a Yamaha Aventage RX-A2060 and it gives three options for dual subwoofers: Monaural x 2, front and rear, left and right. I have read many pros and cons regarding running stereo subs (left and right option). It does seem that many experts recommend going Monaural x 2. What is your recommendation?

Chander Ramsay

Hi! I use just one sub a Velodyne dd 15+ and my room size is 15x15x8. I have bass traps in all 4 corners, rear wall and rear corner ceiling. Do you think i need more subs or is one enough for my room size? Thanks.

Tom Smith

Great vid i only have one person set up so don’t care anywhere else so how many spots should i do where I listening would 4 spots be enough?

Sean Yu

When doing measurements, what does the dBFS mean in this context and what happens when you crank that up?

One Boot Wonder

Excellent video. Many thanks for the share. Could you please shed light on time alignment using acoustic timing as reference in REW using a USB Mic?

Rodney A

Hi Gene, first of all, I would like to thank you for your great videos. I’ve been wondering!! We do our very best with speaker placement and DSP to achieve a nice smooth frequency response with the microphone at listening positioned. But when we do further measurements either side of the hot seat things don’t look so good. Most likely we see troughs and peaks here or there. I was wondering whether these troughs and peaks actually happen in real life, such as a concert hall environment if we were to move from seat to seat, then surely the tonal characteristics of a grand piano for example would change somewhat. I should imagine that our ears adjust accordingly and we accept everything is fine. The question is, are we being too fussy trying to achieve a flat response across our seating area? I would be very interested to hear yours anyone else’s views on this. Thank you, Rodney UK. PS. It could be that any tonal (frequency response) changes in a concert hall are much more acceptable then they would be in a small listening room at home?


Is there a problem having subs of different sizes? Say a 10" & 12" or 10" & 14"?

Drift Taxi

Two subs sittin in a hot tub . . .5 feet apart because that's where room phase shifts them towards for the best response consistency from seat to seat.

Movies Fan

Fantastic advice:)


great vid. Can you do a vid for towers and rew. awesome thanks

Barry Pearl

Hi Gene, I also have the Maurantz 8012 and the Mini DSP HD, would you use both subs out from the Maurantz to the two inputs on the Mini DSP or just the one out from the Maurantz to the Mini DSP? Thanks

Isak Öhrlund

How can you run Audyssey after tweaking levels etc. like that without having it reset everything? That is still a mystery to me.

Andris Romanovskis

Great video, thanks!


Hello Gene, I purchased the Dayton mic and installed REW. I watched your video a couple of times and the additional one Audioholics had on REW room simulation. Something very important is left unclear. I have an older Onkyo PrePro with Audyssey MultiEQ XT. I have two McIntosh HT-2 subs, placed diagonally in the room to avoid co-location and still maintain a living room. In your video you mention Audyssey and how you need to switch to manual EQ for ideal subwoofer management of some peaks and drop offs in the response curve. However, it appears that ALL prepros do not allow you to separately set manual sub EQ’s in conjunction with Audyssey doing the other speakers. If you have passive subs, without phase control, are you just plain stuck??

Kirk Richards

To confirm, you'll have a follow-up video using the MultEq app to EQ the subs, correct? The app or something like the miniDSP are used for EQ, and REW is only for doing the measurements, correct?


Thank you! Recently bought my fourth 15in. and tried to do with Audyssey.

abger saurus

whenever I do this or level match my speakers with decibel reader, should my sub be at "50%" or in the middle? I tried setting all my channels at 75db(A) and sub at 75db(C) I just want to make sure that everything is set up correctly before using REW (also have UMIK)


Hey Gene thanks for this, increasing the LPF for LFE from 80Hz to 120Hz made a huge difference in sound for my room. Now thinking about trying the calibration for my two subs.


OMG YES! Cant watch the vid yet but saw the title and Im so stoked! This is perfect timing, just while I was tinkering with my dual r115sw’s and minidsp again! ?

I still come back to many old vids, so much truth and knowledge in them, reckoning this one will make a fine addition!!

Toby Hines

I've had My REW mic. for maybe 5weeks. I really need to get on with it.

ILoveCookies X

have you tried using the ASIO drivers? allows you to measure L, C, R, LS, RS and LFE channels

Mario Supa

Hey Gene how's it going ? This is my first time posting on your channel. And this video gave me the idea ask you a question on powered subs for a 2.1 music only system. I'm putting together my very first bookshelf speaker system, due to room limited real estate. My question is in your opinion which powered sub would be better for for a variety of music. I want to stay in the $500-$1000 price range. Thank you in advance.

Kevin Eschbach

Looking forward to the Audyssey video!

James M

Who the heck disliked this video? If you chose this video based on the description, it delivers. Some people are never happy I guess. Thanks for the video Gene!


Very interesting, I think everyone with this hobby tries some version of this. Frequency resp. is much more audible than phase or group delay? Does the Dayton Imm-6 work at all for this?

Jonathan Fielding

Gene, are your fronts the RBH speakers with the granite cabinets? Shane demoed those for me and they have an incredibly wide sound stage, or rather, wide sweet spot.


Are you playing your receiver at reference level when running your sweep? And should I be leveling to 75hz on my mini DSP? Or am I leveling subwoofers for the maximum response ? I’m lost lol

Boyfriday Enterprises

Is REW just for running base? Btw how ta feeling?


Can you use REW to level match subs instead of using an SPL meter?

Dan Larkin

Can you do a video on how to use REW to set the eq that’s built into a home receiver?

Retired at 49

Ok something that never gets explained is how to hook up "rew" to a reciever ?!...example ... when using "rew" do you simply hook up a laptop to your reciever (how?) Or do you use a separate "dsp" and use that connected between your sub out from reciever and the sub? In other words how exactly do you use the corrections you make with "rew" into a avr reciever or amp? There are countless videos on how to use rew but nothing I can find on how to implement rew settings into a avr or amp! Thanks for any help!

Apple sauce

While playing around with REW what I found out first is checking whether dual subs are in phase each other by listening around the room and whether response curve is satisfactory enough between 20-80hz. Once that's done I missed the point Gene try to come across from 10:15, is that check if dual subs are in phase with main speakers at the crossover region around 80-120hz. I had a dip around 80-100hz and mistakenly boosted DB, so instead what I did was changing both subs from 0 to 180. It did the trick while also maintaining similar response from 20-80hz.

Marcin Mat

Great tips Gene. Thank you very much. All the Best from Poland.

Mohamed Irfan

Please help me in how to adjust the frequency gain information in to audyssey multi EQ.


Gene, how does MiniDsp affect what's been layed out in this video? Can you perhaps do another video showing us how to use REW and MiniDsp to EQ, align and bass manage multiple subs? Really appreciate your channel and all the helpful tips


Your lighting is a but lacking. The audio is noticeably better. You might invest ~$100 into a simple light kit. Screen capture software makes this type of video look better too. That way the bad color balance is less noticeable. Thanks for the great content.

Retired at 49

Sigh....ok the title says "how to calibrate multiple subs using rew". Maybe it's me as I've watched this video multiple times and you have only discussed how to use "rew" software to determine the frequency readings on a particular speaker or sub. I must have missed the part on how to use the readings you get from "rew" to implement changes to the avr or amp. There is no info being given on how or what to do with the info rew gives you to make changes to the "Eq" in an avr or amp. I totally respect the fact that your giving your valuable time to us free of charge and I hope I dont come across as rude but I have to tell you this is so frustrating as a "nube". If you could produce a video on how to actually "calibrate multiple subs" and not just how to read "rew" that would be awesome. The info I'm seeking is let's say my subs are falling short in certain frequency curves ,how do I take that info given by "rew" and implement changes to the settings in my avr or amp? If there is a video out there that does this I havnt been able to find it! Lol! I'm will pay money for this info!..lol! Fortunately the gentleman on your video that came after this one on how to use "rew" answered one of my questions. I think his name is Mathew Poe and he straightened me out to understand I need a "dsp" between my avr and subs. But alas how do i make changes on the dsp with the info i get from "rew". My next step is to just hire a "guy" to come calibrate my system as I'm totally cool with just throwing huge amounts of money at my particular problem!...lol! But seriously it cant be that difficult. I think my problem is just finding the right info,as for some reason it either assumed by gentleman like yourself that this is common knowledge or I'm just a complete and total moron!..lol! I would really like to think it's just that alot of "assuming" is going on and not the latter!...lol! Again thank you for your time!


Great video, thank you.


My single sub looked like a 100Hz sine wave. Two subs got it closer (not perfect...as I'm using two vastly different subs).


Gene, I have the Pioneer SC95 AVR
, it has 2 sub outputs, but do you know if they are independent of each other?


Thank you for sharing know how! Wish you all the best, Genius Gene!


Hi can you make a video on how to calibrate a home theater system running separate amplifiers on all channels,thanks

Christopher Kociban

Dirac Live only has the option for 1 sub during calibration. Would you recommend using REW to calibrate multiple subs? And is a miniDSP needed for sub calibration with REW?

scotty miller

What volume do you have the receiver on? I usually do testing at 15 on my Marantz 1603. Also, do you want to get the level as high as it goes but doesnt clip? I usually bring up the level in the -15 to -20 range for the sub and my speakers seem to be down closer to 0 to -5 with the same volume in my receiver. Just trying to figure out this correctly as many people dont go over that. My in usually gets to 0.2 -1. Is that normal to be testing the mic to that kind of levels? You're are way different as they are very low compared to mine(volumes)

Shane Tregurtha

Excellent video Gene!
I am using an Anthem MRX-720, taking single sub output into miniDSP 2x4, then feeding two SVS PB2000 subs. It is my understanding the two Anthem sub outs are paralleled, hence why I use miniDSP for individual level and delay. Rather than use REW, I use ARCs Quick Measure to set delay and level variation between the subs.

Question: Is there any technical difference between using the miniDSP delay vs the SVS phase control? If they are the same thing, I could remove miniDSP from chain to simplify things... Although I do find it nice to be able to tweak the sub settings from laptop rather than going back-and-forth behind the subs. Hope I'm approaching this the right way? Your thoughts much appreciated! ?

Kevin C

Hi Gene, I’m running 2 SVS SB1600 ultra’s and I’m running a 5.2.4 set up.
I’ve run REW a few times with good results, but I’ve never adjusted the phase. I’ve used the the EQ on the subs to adjust out peaks and nulls. You had mentioned not to worry about the nulls as much as the peaks because you wouldn’t notice them as much. I was doing that all wrong. I was boosting the nulls. Now I going to redo REW and try adjusting the phase and see how that affects the curve. Side note I want to add just by moving my subs 6 to 12 inches made a huge difference on my REW curves. Thanks for putting these videos out. I don’t think I would have attempted REW without them.

Cal D

How do you set time alignment and phase on a Denon X4400H? Do I run Audyssey first? Then turn it off and use REW? Then run Audyssey again?

Mark Shueard

Are you mean to use Audyssey setup first , or not at all?

gabe martinez

How do you adjust the delay? I have a marantz

Charles K

So I have done some sewwps in my home recording room. Totally amazed with the results. I lost a little bass volume however the frequencies felt better to me. Would you say I could turn the sub speaker up a little to comensate?

Pyramyd Seven

Wow. Very nice. So, I humbly ask, how do I set up studio monitors to accurately produce what will be ultimately reproduced after all mixing and engineering is done? Whew....

Alejandro Saurez

Great video! Hope to watch the ARC video soon!

Elroy Newbie

Sir, You should seriously consider downloading OSB... instead of making a cockeyed video of your TV screen! It's a screen recorder and its free ... check out: obsproject-dot-com.
Or for a easier to navigate, more straight forward screen recording program check out filmoraScrn: filmora-dot-wondershare-dom-com/screen-recorder


Really helpful info and nice video quality. Im left wondering, is there a workaround if your subs dont support variable phase adjustment?
Also if someone already has a usb mic like a yeti or samson, will they be effective?

Ming-Li Yee

Nice video. I'd recommend to use ASIO device drivers.


Hello Gene, I'm very interested in learning how REW works more completely so I can use it to it's full potential in setting up my subs correctly.
Are there any programs/classes that you are aware of that someone can take and learn this software on a classroom environment?
Thanks for any tips, suggestions
Troy in Atlanta

The Swayne

Love seeing this type of content.


Hey Gene. When you were adjusting phase, Did you adjust both at the same time or just one sub at a time? Also did you just move each sub knob 1/4 turns? Thanks.


Do you still use the minidsp in your main system?

Theatre Mad

Gene, if your using your velodyne dd15+ subs can’t you use the the built in software and mic that came with you subs to get good results

Iron Maiden

My method is to put my floor standing speakers on top of the two subs. If the woofers in the speakers are pointing at me then I'd expect the subwoofer could benefit from pointing at me as well. I have a bi-amp AVR so I run two floor standing speakers for the front left and for the right channels. Both speakers fit nicely on a sub.


Thank you for a great demonstration on the use of RAW software. What is your take on Dirac live as an alternative? I like the RAW approach because I believe you can learn more of a complicated process but there is a steep learning curve. I also like the Dirac live software because it suppose to calculate the needed adjustments within a short period of time. Please let us know what you think of them both. I am looking at purchasing a MiniDSP and not sure if I should get the Dirac Live built in version or go with the RAW solution. Thanks.

Blake M

You seem super depressed here, everything okay?

Fabio Zago

Do you make the phase adjustments and eq ( in svs app ) before or after run audyssey?

Joseph Franzen

Hey Gene, I know this is an older video but I finally took the plunge into MiniDSP and your plethora of knowledge in terms of proper measurement and EQ usage has allowed me to really dial in my subs. You’ve got no idea how much you’ve helped me man!

Keith Raufer

Thanks, what about Dirac? would you recommend only measuring 3 feet max distance apart?

Freddie D .Richburg Jr

The microphone I have is the miniDSP UMIK-1USB. I have dual SVS SB-16 Ultras and a DENON AVR-3313ci receiver.

David Martins

I really like your videos but you need to improve your studio. Lightning and decoration. Zero fidelity channel is a good inexpensive example.


Thanks for the great video Jean. Big fan of audioholics and the information you guys put out which is very helpful. I followed your other video with the MiniDSP in the bigger Room where you have the 5 subs, and that was awesome work as well. My own setup is a 7.3.4 atmos setup in a dedicated theater room. The bass is tweaked using the MiniDsp 2x4, REW and a program called called MSO which is awesome, FREE and works similar to the SFM software from Harmon. I truly believe that the MSO program could help you achieve the same tight consistency seat to seat with half the time spent. You may want to check it out.


This must be for the more advanced enthusiasts.

Texan Range

Thanks for this !


my graph shows less than 0db on graph, am i doing something wrong with REW, can someone help please..
at 70hz it shows 80db on graph and on 20hz it shows -20db on graph, i brought umik-1 and started measuring with rew that is what i got. Can someone please help

Jesson T Varghese

Hello Gene, thank you for this video. I have a query. Are you still suggesting Dayton UMM-6 Microphone or you have any other model which you consider better than dayton? Please reply.

YouTuber Anco

Great if I had all those toys but I just have a regular receiver 7.2 and used the calibration on it that’s all lol


Gene just to confirm you recommend not using auddesy on the receiver at all? Or do that first and then use rew?

andrew Last

Good video Gene I have the MINIDSP microphone its good for me to see this if I did mine correctly .I am in a condo living room so different from a house .I have two subs .IN my setup. I saved my charts from the mic .I can always go back and see .

Ashish D

I was hoping to see how to "mess" with the phase? is there really no science behind it? is it really hit and trial?


Multi-sub optimizer software

Loh Suan Khoon

Thank you for sharing......

Tibor Makai

Great video. It is worth having two subs, with a cheap receiver that has only parallel sub output? How would I even know, if I have parallel or not output?

Wil Thomas

Thanks so much!

Cal D

Gene, did you ever make the video regarding the Audyssey App?
Great video by the way!

Charles K


Demon Returns

Damn looking at the the level trim your speakers are set at that room must be very symmetrical where you placed the speakers because basically the level trims are identical for each set of speaker

K Dub

It's a bit of an unorthodox approach to setting up multiple subs but the results look good. Better to increase the AVR's small freq crossovers well above 80hz to eliminate any influence. REW says to avoid adding phase/delay to subs individually. Only need to add delay or invert one sub, the closest. And the sub crawl isn't effective across a sub's spectrum and multiple seats.

In any event, it's easier to use a single sub output from the AVR, of course gain match both subs, add phase/delay or invert the closest sub to optimize nulls/peaks across the two sub outputs. Restore the AVR's proper crossovers etc. Then use the AVR's configuring function (Audyssey or similar) to match subs (calculates distance/SPL) to the rest of the speaker configuration aside from subs.


This is great. Thanks.

Edi Charana

Awesome information!! Thanks! One question though - is it preferable to adjust phase directly in the sub or changing the distance in the receiver menu? Thanks in advance


Really cool. Thks. The actual adjustment for my mother and law would be at the toilet sit :)

RoughNeck 201

Thank you so much for taking the time to make this video. I've been waiting for you guys to help us out. Thank you so much.

Wil Thomas

If I buy the MiniDSP mic, do I really need the MiniDSP 2X4 too?


any video about Dirac ? :) pretty please

Alexander Scott

Yes. Most important piece of enlightening information heard here is "good easurements at the critical crossover point between speakers and subwoofers!"
This is rarely discussed, yet absolutely important(besides flat response)
Good job Gene

Paul Mohr

I am almost afraid to get this software and a good mic. I am worried it will show me problems I didn't know I had that I can't fix lol. Its a small odd room in the attic with lots of clutter because its also used for storage. Also not a lot of choices on where I can put the subs. I could try a few places though. Also really no way to employ any kind of equalization without seriously upgrading my equipment or spending money on special stuff. I have a radio shack digita spl meter, but not sure I trust it. I have heard they are very inacurate and actually vary from serial number to serial number and different runs because of how they source the cheap mics they use in them. I have used audyssey, them compared it to using my meter and they are not always the same. Especially for the center channel and sub levels. And I just don't know which one to trust lol. Audyssey turns my sub down to like -10 and the RS meter wants me to set it quite a bit higher, too loud to be honest. Also my center channel is always louder than the rest of my speakers and always has to be turned down quite a bit. Which urks me because they are supposed to be a matched set of speakers all rated at 90db sensitivity.

I just got a second sub yesterday actually. I now have two polk psw108's. I know, not great subs but I am poor lol. I tried putting one in the front of the room, and one in the back. Then I did the subwoofer crawl thing too. Both positions did do a great job at making the bass the same everywhere in the room. You could walk around the room and it sounded the same everywhere. Kind of amazing how that works. With one sub depending on where you were in the room it could get kind of boomy. That being said I only have one chair in my room so I really don't care what it sounds like 4 feet to the left of me lol. And in either of those positions the bass just didn't sound right to me. It was a bit boomy, like maybe there was a bit too much in the 35-40 hertz range. And it didn't seem to blend well with my other speakers at the crossover points. I dropped each one right next to the main tower speakers and it seems to sound better to me. The subs seem to blend better and there is for sure more impact with two subs vs one which makes sense, its moving more air. These subs really don't play that low because they are cheap. With one sub it was more of a hearing thing. You could hear the bass down to about 30-35 hertz, but you really couldn't feel much. It was just filling in the sound that the other speakers couldn't produce well. Which to be honest, that is probably what these were designed to do. Most of these cheaper "sub" woofers are really just powered woofers in my opinion. Meant to be paired with other speakers that lack deep bass. Adding the extra sub made a big difference. It for sure has a more tactile feel now. I can feel 20 hertz now and it actually excites the air in the room like it should.

I also have a large 15 inch sub I built myself that plays below 20 hertz. But it just works too well to put in the attic. Not to mention I don't want to drag it up two flights of stairs. This thing sounds and feels awesome, but it effects the whole house when you turn it on. I just can't have that in my current living situation, its not an option. I do have some bass shakers I could use though. I haven't installed them on my new chair yet though. They kind of work, but it isn't really the same sensation as "real" bass.

Wow, I just wrote a book that I am sure you will never read. Sorry about that. Love what you guys are doing and F the haters.

What is DSP? How To Use REW to Tune Your Speaker System

What is DSP? How To Use

What is DSP? How To Use REW to Tune Your Speaker System

UPDATE 1: Make sure when using autoEQ, to set the graph to Var smoothing (not Psychoacoustic) as this affects the correction profile. Also play around with Individual Max Boost, Overall Max Boost, and Flatness Target Levels. I currently like using (6, 6, 3) but experiment for yourself.

This is a beginner's tutorial about how to use DSP room correction for speakers using a MiniDSP UMIK-1, REW, & Dayton DSP-408 digital signal processor. An alternative to the Dayton Audio DSP 4x8 is the MiniDSP 2x4 or 2x4HD.

After applying this room correction, my speakers sound much better to me. I still applied tone control adjustments to suit my personal taste and the fact that I typically listen at low volumes here and adjusting the bass and treble accordingly helps intelligibility.

it seems a lot of speakers even the old ones are using dsp like the jbl 305, though the recent elac Navis ARB-51 choose to not use a dsp what are your toughts ? do most use a dsp for only crossover or also for equalisation ? will you test the elac Navis ARB-51 ? thanks for your great videos.


That was way more useful. I've watched a few videos and it just shows people making changes, but not explaining why they are making the change.

Steven Oostdijk

All very interesting, but perhaps instead of throwing a few hundred grant at measurement equipment and DSPs for optimizing one specific point in a room one could first start by investing in speakers with less room interaction, e.g. a set of Linkwitz lxMini’s. That way more people will be able to enjoy good sound quality.


Great video. I also routinely use dsp in my builds. Curious what you think about the minidsp vs. the HD version. I could not get enough voltage on the output of the minidsp to get good power from typical amp boards (i.e. without adjustable gain), so I had to go to the more expensive HD minidsp. Thoughts?


Anyone else watching this this on REW-calibrated laptop speakers?

Marc Foss

Great video...so helpful, thanks very much. Would it be possible to contact you by email regarding an idea/proposition?


Good job explaining something pretty complex in a simple way! I was planning to get these tools to setup & tune the system of a small event space I'm working on.

Nazrizal A. Tajuddin

Hi Joe, ive been listening to this video, you were saying if you doing ok and might not work for some people... in my opinion, in sound tuning, there is no right or wrong, or what so ever... ive been tuning for more a decades, on this video... i give you a thumbs up!!!! please do keep posting on great work! tools is to get your tuning rite on track fast, but in detail on tuning the sound, always trust your ears as machine dont tells you it is right sound or it is a great sound too!


Great review!
I have been out of HiFi and Audio for many years now. I ran a very large 3-way system with 6 mono blocks managed by a 1st gen DCX2496. It was like magic to sit with a laptop and measure and adjust the filters over the RS232 serial port. I still have the DCX2496 but have sold all components of the large system long ago.
Getting back into Audio is a brave new world. =)
I love how easy it is today to get into audio without it costing a fortune.
Keep making great videos brother! =)
Greetings from a sunny summer in Sweden.

I have used EqualizerAPO on PC. Latency and CPU usage are negligible in normal usage. But it does not support exclusive mode like ASIO, so for music compositing you better get an external DSP.
I have got the MiniDSP DDRC-24. Not cheap, but really worth it. Not sure the phase correction change a lot of things in a small room, but Dirac correction made a bigger sweet spot. Plus I have presets depending on my location : in front of the desk, couch or dining table.
Also bonus with an external dsp, is that I can use it both for my PC and my console.


Spanish shame.


Bugged audio mechanics

Mario Gonzalez

Having this, will it override a DAC? Does this have an internal DAC? Im looking to add a sub and room correction but I do not want to have my current DAC be worthless.


Is this needed if my receiver has audssey or dirac live? Is it the same thing?

Joe Lopez

I'm confused how is a speaker supposed to connect to those rca jacks

Chef Chutardo

thanks ! i learned a lot with this. gonna have to buy one of those dsp thingy's ?



Neil Hansen

Cool video, Not sure i understand how ur getting pink noise sound out of ur speakers. Where are the hooked up to?


You don't like using a house curve?

Hans Mayer

Excellent tutorial Joe. Much appreciated.


So for HT DSP room correction is great, there are a ton of speakers and two subs to equalize and integrate, the source is also digital so the only conversion is the D/A prior to amplification. My receivers use Audyssey multi-eq xt32. For 2 channel stereo I try to stay away from DSP. I’ve used ARC and the results where horrific. I’ve returned it and went with as pure a signal as I could avoiding unnecessary A/D-D/A. But that’s just me.

krishna chaitanya

Great video , thank you


To what extent can room correction account for the low end mess caused by large monitors in a small room. I have a pair of large monitors with 8" woofers that can hit below 40Hz but they are often unwieldy in my bedroom. Would a calibrated Mic, REW, and a miniDSP HD be a good approach?

Shawn Macdonald

Hi Joe. I have been watching all your videos over the last month or so, as I was looking to upgrade my stereo system. I ended up buying the Fluance Signature towers and center speaker. Also 2 SVS SB2000 Pro subs. I am happy with the sound, but I assume I have issues with phasing, placement ect. My Onkyo TX NR636 receiver has a mic and correction system. Do you know if it is any good to use? I don't think I could use a dsp on my system as I mostly stream music through spotify and Youtube. Would it be a good idea to buy the mic you used just to get an idea of where im at?
Thanks for all the help you've giving me already from your videos.

Charles K

I'm new to this. Stubbled on this video. Dont have DSP... so I guess now way of applying eq settings :-(

ventura rodríguez vallejo

Great an valuable technical video!
If only I could buy a pair of calibration mikes...
When I was studying my Sound Technician Course, they had a pair of B&K costly mikes for this very purpose into the monitor/recording room. They used a paragrafic analog equalizer for corrections every time there was a change of monitors, and they were pursuing all the time a frequency response as flat as possible.
Nice times were those...


Very helpful video. Thanks for posting!


Hi how are you, Im interested in this tecnology ,help me please to understand, I don't have a dsp device,I do have a RME adi2 dac Wich allow me to implement eq, so if I measure the room and put the parameters in the RME I Will get the same result ? Or I still need the DSP ? Thank you so much


I myself prefer variable smoothing. It keeps a lot of the low-end peaks and valleys, while not going crazy on the highs which always change due to position anyway.

Then, instead of using individual filters, I export the impulse response as a WAV and use the convolution filter on EqualizerAPO, and use the Fruity Convolver in FL Studio. An impulse response has essentially unlimited filters, and the CPU usage is always the same.

I believe the MiniDSP supports FIR/Convolution filters as well.

Pristley Devassy

Is any one kind to work on a measured file and help to fix the issues ?


I use the dayton DSP in my car and Uunderstand how to set it all up in that enviornment... I am confused though for in home. This is gonna sound liek a stupid question, but dont flog me:) So I have a Pioneer Elite sc-79. I am to run my mcacc on the pioneer at all if usinf the dayton? It sounds repetitive to do both. 2nd, I am confused on how this is used with the Pioneer as far as hook up. Would you run the left and right pre out into the dayton, run rew as you did and then the L/R out put on the dayton back into the input on the pioneer? Even then, if you change inputs, to say your BD player, then it now would be bypassing the dayton corrections? Sorry, but beginer means begineer....lol

Edward Plunkett

Thanks for the video. I’m trying to setup infinity rsii in my room. Going to give it a try.

Nick Ames

Keeping the microphone close to your head will ensure that Acoustic energy reflected from your physical head will be picked up by the mic.

This is not necessarily a good thing.

Bill Macfarlane

Thanks, that was well done. Very educational.

Nigel Wharton

Hi I am from.trinidad going and buy Dayton audio dsp 408 to put in my car .looking for more videos . Great job .✌

Thomas Yamaguchi

Tks very good.

Rayner Stuel Galid

Hi Joe. Bit late to the party...but how do you hook source/DSP/amp/speakers. I am thinking of using miniDSP as an active crossover for a DIY 2-way speaker.

Neil Blanchard

Very helpful, indeed - thank you sir!

David Lavallee

In addition to being on a boom/stand, should the mic be pointed at the ceiling?


So this eq only works when your playing through your computer? It doesn’t save any of these speaker eq adjustments in the receiver?


Great vid. Which one you prefer to use??

Dsper Fk dsp

Dsp is a streamer that beg everyday

DJ Rez

so how did it sound afterwards?

Brodey Dover

Exactly. Use measurements AND your ears, verify measurements after and see what your ears are telling you.

k b

ur the shit man... you've helped me take my speaker obsession from elementry school to on the road to phd haha.. I bought the DINAS and now i think im going to buy some other tools like DATS & possibly omni mic 2..


Many thanks!!!

john soprych

OUCH! How Barbaric! A Lens with back element facing up & uncapped :O

Justin Gillette

PEQ is fully adjustable you can select exactly what frequency, you can control gain or cut amount, you also have Q, which is the band width.  GEQ has fixed frequencies you can adjust and usually has set Q all you have is gain or cut control.  while useful graphic is old hat, PEQ is king.  just know that any eq applied will effect other places in the room and not always positively.

Chris Freeman

Great video! DSP always seemed so challenging but now I feel like I can take it on. Thank you

Jerry W Davis

Lotta work. Thank you.

Vincent Cheng

Really nice instruction. thanks for sharing. appreciate your efforts.

Mike Goppert

Nice demonstration Joe. Thanks.

analogaudio rules

Can i use rew without a mini dsp or any other dsp hardware and just with my computer and my dac? I'd rather run it directly so there is no limitations, I'd rather not be limited to 96khz and i want a balanced connection. Can use this with foobar?


Excellent tutorial, thank you! I just started playing with REW and that’s exactly what I needed.

Pascal Payant

Is there anything to calibrate perfectly a 5.1 set up for mixing... Most of them are stereo only


Hi what is the brand and model of your sound card thanks

Richard Cote

How do you measure with the mic by only connecting the mic to your laptop or computer?
If you wanted to play pink noise through your speakers via a test cd through your audio system, without actually hooking your audio system up to the lap top, how would you do it? How would you configure rew to do this as you wouldn't generate the pink noise with rew?


You never want a flat response. Start with a 1dB/oct slope down and work from there. Look up Harman’s target curve, they have 20Hz like 9dB above flat.

The reason is flat isn’t actually flat. Human hearing has adapted to know how a flat sound would sound in a room, which is treble loss due to absorption and bass boost due to reflections.

Mr Mr

Learned a lot man, thanks for making the video and sharing brotha ???


do you have a video using the mini DSP HD to calibrate multiple subs?

Buddy Flankwood

is this the same as the denon audyssey system?

Steve Phillips

Excellent. Clearly explained and useful, thanks for taking the time to make this video and for sharing it.

any updates I just got my umik 2 days ago

Dwight Cotino

Great video thnx .... got 1 question tho..... some people use RTA what is the difference and which should i use for car audio?

Randal Robinson

Great video. Trying to get information on how is like going down a rabbit hole. I do have one question and hope you might help me with. I was thinking of integrating the DSP-408 into my home theater after ther receiver and before the speakers. The main question is does this method require the output to be amplified or can the speakers handle them without?


joe, would you leave the master audio on the dsp at 0?

John Chad

Thank you so much for posting this video. I'm very new to this world and you explained things so clearly. I just finished wiring my truck up and I'll be doing measuring, testing, and calibrations tomorrow. That REW software looks fantastic!

Stéphane Benoit

Thanks a lot.


Your speakers seem to have BBC dip. You probably don't want to correct that.

vilu tikkanen

Thanks for the great video! I have just started testing my new toys, minidsp 2x4 and umik-1 mic and so far after a few hours getting into it I just know already that this going to be amazing. I have not got all the details correctly and just learning the essentials but the first tests have showed me the revelation. The final missing link in a chain from the source to my ear. The room is the last link in the chain people! Room correction is essential!! It really makes the difference. You go from boomy and mudded to crystal clear, precise sound. This is it, Guys!! Ok take care, from Finland.


I am surprised you have to manually enter the REW data into the DSP and not just copy the data file over. I've been working out all my system parameters mechanically as in speaker type, positions and , being triamped, individual levels, seating positions and getting it to sound good to me as well as being practical. My music room is a multi use room, not dedicated to sound only. I use no eq at this point. I will literally change to a different speaker before adding eq up front. I save eq for absolute last and hopefully just as a fine tuning. I've been sitting on my miniDSP for almost a year getting all the rest correct first. This video was a big help seeing it actually done. Thanks.

Home Theatre Engineering

Hi great video. I noticed you mentioned initially measuring at 85db but then turn down to measure at 75db which as you rightly say is reference. But also the pink noise signal for reference level is not full range but 500hz to 2khz. Of course subs are at 85db but the 10db difference is managed in most avrs and processors.. thought this might help some folks?

Naeem Samad

Great video ! You’ve covered certain areas

Ashish Patel

Very useful video. Thanks.

Phil Barbera

What if I need a dsp for 5 channels? My pioneer avh has 3 sets of rca’s...front, rear and single sub powered by 5ch amp. Can I somehow use the 408 still? Thanks.


Awesome stuff Joe. I hate the fact that I have some pretty good equipment in a dedicated theater room and have not been able to use REW. I have the Pioneer system that does all the setting for you after running a room analyses, but Id like to do it myself. Just recently got back into car audio and just bought the dayton, and plan on using rew to tune my car. Your video is very good at explaining this for a novice. I will be asking more questions:)


Awesome video thank you very much for all the clear information I appreciate it!

I did have a question that doesn't seem like there's an option for in the software but I bought the Bluetooth USB adapter for it and it says you can stream music directly to the DSP and I'm basically eliminating my double din radio with a custom 3D printed dock for my Galaxy S10. now when you select your inputs is there an option to use the Bluetooth input or how does that work? Because I won't be using inputs 1 through 4 physically. I have the dayton audio 4x8 DSP by the way.

Matt Denson

Excellent tutorial. How do you determine what target dB you want? Is it a measure of how loud you want to play?

Prashanth B

Only 7 frequencies ?
I did similar stuff in AUDACIOUS (Linux) with 2000 bands or more. Result was very good.
A small before after demo would have been nice :)

Warrior Gods

You explained it very nice Joe, but I still cannot understand how to use REW and what to set my decibels to and my range and all of that. I need a tutorial on what those numbers mean and how to EQ my peaks or nulls assuming I do have some


7:42 ?? great video man!

Awesome Joe! Thanks for doing this!
I was talking to a sales guy at Part Express a few weeks ago when I was considering trying out these "exciter"s. He told me about the DSP that they sent to ya, and if I had the money I would've bought all the parts I was considering, but decided to go another direction instead.
But, someday I do want to try this DSP! So, this vid is going into my collection of knowledge! THANKS AGAIN!

Hey, would you Please do a review on some of the P.E. exciters?!?! There's this guy (a total Gnerd like me) who has a review and test on them using several different materials. But, I'd love to hear your honest thoughts as a fellow audiophile. Here's a couple vids to check out:

Continental Corporation's "Speaker-less car audio system by Continental - overview and explanation" [1001cars] - https://youtu.be/3yWnZFLX0FE
Note: @14:30-ish my RTA says that there's 50Hz being recorded/produced so that's pretty impressive for these little exciters!

Here's the Gnerd dude (BTW he's pretty cool, and I think he's a teacher) - World’s Best Speakers! [Tech Ingredients] - https://youtu.be/CKIye4RZ-5k
This one vid has about 440k views and yet he only has 135k subs!
He starts testing materials at about 15 mins but at the beginning he tells us what two (actually three) materials are the best.
At 27:27 mins he reveals the REW SPL graphs.

FYI: my RTA is actually reading the signal coming out of my MBP via a USB D/A convertor then the signal goes on to the power amp, so, no, unfortunately I don't have a $90 mic (I wish I did, but then I'd be testing the output of my Epos speakers - not the actual signal from the YT video he made).
Note: at 39:00 mins I'm seeing bass in the mid-60Hz range (with some showing in the low 40's - but this is more than -20dB from the peaks), some highs going up to 12KHz, and some showing all the way up to 20KHz - but it's more than -10dB from the peaks).

Just in case you're short on time: here's a short 4 min vid by Bongiovi Acoustic Labs doing an install in a minivan: https://youtu.be/jvxGJ-d0OC0

One GREAT ADVANTAGE that the exciters have is that they use approximately 1/10th the watts to produce the same SPL! This is a HUGE advantage no matter where the sound system is installed (inexpensive TUBE AMP anyone? WOOhoo!) or for portable systems too (battery powered bluetooth speakers, car installs, home installs, etc.) In fact Linus Tech Tips has a vid on a smartphone that has sound from the screen rather than from a speaker (I haven't seen it yet, but I'm pretty sure it's an exciter.)
However, there is at least one drawback: they need a relatively large surface to "excite" to produce adequate SPL. Also, they can't reproduce much SPL sound below a certain frequency (~175Hz if I remember correctly), so a subwoofer would still be needed to get nice booming bass, and they don't do much above ~8k so a nice (ribbon?) tweeter would be needed for the extension.

I was going to buy 6 exciters, for six panels (of two different materials - Balsa end wood, Styrofoam (OR ceiling acoustic tiles which he recommends)) and 3 cheap ribbon tweeters to get that full extension up to 20KHz, and the P.E. DSP unit to divide the sound frequencies for all 4 sections (including my existing 10" Dayton sub). But, the cost racked up quickly the more complex I got (I'm a bit of a detail perfectionist, which is to say I like the highest quality I can get for the money). IF I was happy with the sound I was going to sell my EPOS ELS surround sound speakers to offset the price.

Well anyways, I'd be interested to know what your thoughts are on the exciters - as I've never heard them IRL, only on YT - and that's through my (ELS series) Epos speakers.

BTW - WHAT VM (Virtual Machine) APP are you using to run Win7. I have Win7(64) on an authentic MS disc (yeah, a CD/DVD, crazy right?) Anyways, I have a MBP (running MacOS 10.13) so I'd love to hear your review on that app and any other VM app's you've tried out. THANKS!
