The ones that dont know how to do time alignment... , just buy a Mosconi DSP, and a pair of in ear Microphones from thomann and it will do it perfectly automatic.. ;) It will also calculate the fase automatic and set filters automatic if you tell it to do that. Job done. Internal RTA, internal tonegenerator, no errors in the measurements. Its very cost effective for the regular do it your self. REW True RTA single condenser mikrofone Is all a very long process to reach good results with.

[@bbfoto7248]

The miniDSP C-DSP 8x12 v2.0 Dirac Live unit is incredible in this regard as well. It fixes timing, amplitude response, and phase 110% better and MUCH faster than even some of the best experienced manual tuners can. It has a few quirks to figure out as the DL algorithms and measurement protocol weren't really designed with a nearfield/small-space, highly reflective vehicle cabin in mind, but it's still amazing what you can achieve in a relatively short time.

[@mindosy]

@@bbfoto7248 :DDDD

[@mindosy]

but no one in pro category uses miniDSP C-Dsp because of its terrible sound

[@bbfoto7248]

@@mindosy I don't compete, but I'm a musician of 25+ years (Saxophones & Drums/Percussion). I have 4 vehicles with high-end systems using Helix DSP PRO MK II, Helix DSP ULTRA, Gladen Aerospace 8x12, and miniDSP C-DSP 8x12 DL. I've been using DSP and tuning my own car audio and home audio/studio systems since the 1990's. I use REW and Systune with Earthworks professional measurement microphones when tuning. My own home studio recordings of my sax & drums, and other typical "audiophile" recordings including EMMA, IASCA, and Stockfisch AYA discs, sound the most REAL and LIFELIKE in my system with the miniDSP 8x12 DIRAC LIVE...by far! The speakers in that system are Purifi PTT6.5 as midbass, Dynaudio Esotar² 430 midrange, and BlieSMa T25B-6 Beryllium tweeters with TWO 15" Infinity BETA 15X subwoofers in I.B. configuration. Other systems use Focal Utopia 8WM, 3.5WM, and TBM tweeters with Raven 12" subwoofer. And another system uses Purifi PTT6.5 midbass, Excelsus XXM325 3" mid, and Gladen Aerospace 20 tweeters with H.A.T. Clarus 15 subwoofer. Last system uses ARC Audio RS1/4/6 3-way components and Boston Acoustics SPG555 subwoofer. So I'm no stranger to high end SQ and I know what REAL acoustic musical instruments sound like in real life to compare my systems. ;-) The miniDSP C-DSP 8x12 DL sounds fantastic when it is implemented properly. I have tried the Zapco HDSP V Z16 which does sounds great (when it worked), but when I tried it in early days there were WAY too many problems and quirks with its software & firmware, and horrible dealer support, so I returned it.

[@mindosy]

@@bbfoto7248 nice setups, many of dsp you mean was tuned and your insights about Zapco is true, but one more is that Zapco sounds very "digital", Helix flat in bad side of flat, maybe you are right, but i have no good experience with auto tune audio things, especially that using EQ in sound is the worst thing

[@leoeskelinen1867]

Great work Peter. Information is for sharing. Having spent countless hours with REW i find the biggest challange in measuring tehnique. Static MIC measuring is extremely sensitive to placement. A couple of centimeters creates huge differencies. Measuring right/left ear position also does this. Moving Microphone Measurement over 5-10 seconds and collecting accumulative data with proper smoothing creates more consistent measurements. So, back to my question: Which measuring method do you use?? Maybe gated measurement would be best to try cancelling some reflections?

[@pssound9749]

Leo Eskelinen check out Erin’s Audio Corner channel, he has a video about measurement techniques. I can’t share mine unfortunately, sorry.

[@leoeskelinen1867]

Pssound Ok Peter. I understand. Will check out Erins Audio Corner. Thanks

[@bbfoto7248]

@@leoeskelinen1867 Yes, Erin really knows what he is doing and is willing to share his knowledge. The reflections are part of the total amplitude response you ultimately hear at your listening position. The Moving Mic Method is much faster and gives you very similar results to taking multiple-location, fixed-point mic measurements and then averaging them in REW. There is also other software that is extremely powerful and can reveal more refined and useful data (if you know how to interpret and apply it). But those are not free like REW and require greater understanding of impulse response, phase, modal characteristics, etc. Also look up Steve Kiser in North Carolina, and Mark Eldridge (Mobile Soundstage Engineering) in Oklahoma in the U.S. Also the guys at Audio X Custom Car Audio, Florence, Alabama... www.audioxcustom.com/

[@leoeskelinen1867]

bb foto Thanks for your reply. I’ve been using the MMM as my primary method. Separately one channel ear by ear first, then both channels. Starting with the midrange. What really disturbs me is the big variations in measurements. What is the purpose of using state of the art DSP when the aqoustics mess up the possibility of correct and repeatable mesuring results.

[@leoeskelinen1867]

bb foto Have you used gated measurements? Maybe this is the way to go?

[@lucaslong5368]

This is great information! Thank you for sharing. You definitely have a niche carved out for you. I hope to have my stereo tuned so well when I'm finished.

When making measurements to set delays between the speaker and the listening point, should the measurements be taken from the grille to the listening point? or would it be more correct to remove the grilles and take measurements from the listening point to the base of the speaker cone without the grille?

[@shahidyt]

I’m fitting a JL Audio amp with DSP in my car tomorrow. I was going to have a go to tune myself. You said £300 for tuning, was that the market rate for a professional to do the tune? I want to have a go myself, which is the reason I watched the video and my backup plan was to get it professionally tuned if it doesn’t sound right to me. Thanks, I appreciate the detailed video

[@shaficknazier9125]

Hi, great series and great video. Learnt a lot, especially midbass in doors in conjunction with the Audi build. A question, have you done a centre channel install? With proper upmixer, of cause and your views on centre channels in cars? I have read about AndyW's car (AudioFrog) and read his tech tips, etc.

[@pssound9749]

Shafick Nazier no, i haven’t used centre channel yet, no need in my 1 seat setups as centre image is still rock solid and the passenger wouldn’t have a clue about imaging anyway! 😃 I’d highly recommend using differential rearfill though! 💪👌✌️🔊🔊

[@colbydolby6559]

Excellent video peter! The knowledge you share is greatly appreciated. I hope you do start the remote tuning, after all you share on your channel I'd be happy to pay for a service like that. Question, is there features you prefer about the zappco dsp then say over the helix? Thanks again for your videos.

[@pssound9749]

Colby Dolby this Zapco is dead easy to use even for newbies, whereas Helix DSP’s have so many features and pages, that most people can get lost. Both of them sound great and have head to head accuracy when it comes to tuning. I use both of them very often, to be fair i don’t want to use anything else! Latest Mosconi DSPs have all the goodies too, so i would be alright with that too, but that’s it! Helix is still leading in features and compatibility with REW, but i’m okay with any of the 2 until i can get the desired sound out of them. The Zapco HDSP V is special for me though: pain in the ass to tune with it (new software is coming), but the sound!! ❤️❤️

[@bbfoto7248]

@@pssound9749 Yeah, Zapco REALLY needs to get the software (AND their Support/customer service) sorted out for the HDSP V units. They are so close. I've really wanted to use these new processors in my systems, but they are just not there yet. :( Hopefully soon!

[@pssound9749]

bb foto it is there now, but it makes a massive difference who you buy it from, like my customers getting it from me with all the support. Devices are preset for their system and tested for weeks before they actually ship out, but i wasn’t selling them till i wasn’t confident with them.

[@bbfoto7248]

@@pssound9749 Yes, that's very important. Unfortunately, Zapco laid that burden too heavily on their dealers IMO. No one can argue about the high quality of sound that they produce. I just take issue with companies that release their uber-expensive products too early and when they are "half-baked", which forces their dealers and early adopter customers to become the guinea pigs or "beta testers" while all of the bugs get sorted out. :/ And they ARE NOT FAST at providing updates and getting things sorted. :( They also announced these units MANY, MANY YEARS AGO, and then kept making empty promises all along the way. Ultimately, many of us gave up and lost interest, while during the same timespan Audiotec-Fischer had released and refined/updated MULTIPLE top-notch DSP products with a huge feature set and options. Unfortunately, Zapco lost a huge amount of momentum and market share during that time. And when they FINALLY were released, the actual roll-out and release of the HDSP V units was a complete clusterfook (at least here in the U.S.) and very poorly handled. AND the software was half-baked and definitely not ready for primetime. It's taken more than a year to get them to a point where they are actually semi-stable and usable. Then, of course, there was the change in distributors here in the U.S. which was another setback. While I like the concept of the HD Player & remote, it is crude and severely lacking and restrictive for the current times compared to even the most basic of smartphone music playing apps. I still have heard nothing of the optional ADC/DAC modules that they promised with the initial announcement. Are those available in the EU now? /RANT :-P

[@UKBlue407]

Watching this for the second time, great video. With new drivers, is there any requirement to run them in before doing a EQ? Do they change acoustically (and measurably) as they bed in and settle down?

[@Malakyte-Studio]

Great video! I am usually not a big fan of individual Left/Right EQs in the midrange region because it creates phase distortion if you use "regular" filters (IIR instead of FIR). It may lead to a fuzzy sound image and lack of coherence. Aren't you sensitive to that phenomenon Peter?

[@pssound9749]

Yann LECOEUR you don’t get any of that if the EQ is applied correctly at the right place with the right values.

[@Malakyte-Studio]

@@pssound9749 you did not convince me. 😁 Check the group delay of left midrange and compare with the right one. Also, if you can, check the global phase response of each midrange channel in the tuning software. Each filter that you set creates a phase rotation at the F0 frequency. If you proceed with stereo EQs, everything is fine. But if you start EQing individual speakers of a pair where the human ear is sensitive (typically 20 Hz - 1.5 kHz), you will "defocus" these frequencies. This is why uncorrelated pink noise looks always sexier on our RTAs 😎 When you acoustically sum both midranges playing a correlated pink noise, some of the dips are the result of this phase distortion between left and right.

[@pssound9749]

Yann LECOEUR you see you’re good to go, my help is not needed here! 😃

[@salinaj2]

Peter, Thank you for this video as it is extremely informative especially in one of my cars where I run a Zapco ADSP. Question: I think I am doing it wrong. I run the Pink Noise generator in REW so that I am consistent in my measurements. You mentioned that when running your PAIRED speakers (I.e Tweeters) you ran with Uncorrelated Pink Noise (Stereo) is that correct? Run with MONO (correlated) Pink Noise when measuring individual speakers but run stereo pink noise when running pairs for your measurements? When checking all speakers together do you also run stereo pink noise? Thank you.

[@pssound9749]

John Salinas II correct. 👌

[@salinaj2]

@@pssound9749 If I am running say just the Left three way to make sure they are phased correct do I use MONO or stereo PN?

[@stockleyrod]

@@pssound9749 wouldn't you want to run mono pink noise when measuring pairs of drivers, such as two tweeters? Mono would essentially be measuring your "center image" and verifying there is no cancellations from miss set time alignment?

"There is nothing wrong with Focal tweeters, they just need some tuning" agree Piter but 9 of 10 peoples are "plug and play" means they buy 2 way passive system, mount and play and thats where disappointing starting , simply Focal tweeters on stock crossover sounds horrible , not just my opinion.

[@redacted6115]

Hi Peter, love your videos. I've learned alot. I think I heard you say that you use uncorrelated pink noise? Can you explain why? I've been using correlated pink noise for all my tuning. I do each speaker individual, and then in pairs.

[@richie.rich98]

Think about it, If you're tuning a system you're listening to music in stereo so you would then tune each individual driver with Uncorrelated Pink Noise (Stereo Pink Noise). If I'm tuning a Right side speaker I only want to tune the signal going to that speaker. If you tune with Correlated pink noise (Mono) you're tuning left and right signal for a driver that's only going to be playing right signal giving you inaccurate results.

[@TheAbunai]

Peter. I had a question that I have not been able to find an answer too. The Zapco dsp I notice in the background you have the main volume set at 26. Do you use the dsp as the main volume control and run the source at 3/4 volume (say a head unit or dac player). And if you do use the Zapco dsp as the main volume control do you set your gains with the source unit at 3/4 volume and then the dsp at 3/4 volume.

[@pssound9749]

No, max clean signal from source as well as from DSP to the amps, so you can keep amp gains lower to improve the S/N of the system. Controller of the DSP is usually the master volume, especially when we use digital sources.

[@TheAbunai]

@@pssound9749 so I would oscope my signal from the source (headunit) set that keep the source at that level Then plug the source into the DSP then oscope the dsp output then I can plug in my amps and then oscope the amp gains?
