Benefit of having such a peak in the subwoofer range is: once you EQ it down, it will make less excursion in that frequency range, (bc you put less energy into it), which should result in a more dynamic response of the driver.
Love this series of videos.
Thanks for sharing.
Thank you for this video, I cant wait for the next one to see what improvements kick location brings, but this looks pretty damn good already! I now have to decide what to do with mine..
Thanks again for another video Peter! Happy Nee Year to you as well mate. Cheers!
Excellent video as usual, thanks for sharing. 👍
Thanks for this video Peter! Hope to see the chop chop parts, when you will cut for those ib woofer! This swift will be crazy! Thanks again and have great year end ;-)
WOW. nice breakdown of the RTA. I'm in the planning phase of my new project, a 2017 Honda Accord Touring with Nav. I hope I hope I have enough room to locate a pair of these.
Great to hear you we're sound engineer (from autohifikanava)! I'm musician myself and really into car and home audio! :)
wow! thats some mad skills on th mid eq
I feel lucky to have heard the steg mss3 4’’ drivers in Peters car and I cannot explain how incredible they sound. They’re clear and they’re loud and will shock many people as they did me.
Yepp, they have to hear it to believe it!
For someone considering upgrading from a 2 way (Steg SQ650C) to 3 way, what else (apart from the 3 way Steg MSS) should I consider? I'm in Australia. I'm running a Helix M SIX DSP and an IDQ12.
Peter, there is a JBL sub fuse twin equivalent of focal. It's 7db more sensitive with same 200w rms. It also has passive radiator. Try it out next time. People from DIYMA really liked it
Thanks for the tip. I’ll have to find it as we don’t really have support for JBL in UK.
Hi Eugene, do you have a Frequenzy Respons of the JBL Sub? I could imagine the seat will cover up higher frequenzys from 150hz
Awesome video Peter, thank you. It's really helpful to see how you deal with a less than ideal system and you are the only pro that I see not "poo-poo"ing boost.
If I may ask, when I measure full range for a midrange, do I need a high pass like the 1Khz on the tweeters? If so, is 1octave below FS good or should it be closer to FS?
If you measure them at 85-90dB, then they are safe even without a HPF, otherwise cross them at 80-100Hz.
Thnx for the videos and the informations peter, it did help me with my install.
However i have one question, i have an audible floor noise (white noise) coming from all speakers, i tried to lower the gains but the noise is still there it’s not as loud as before but it’s noticeable, although the noise is gone when i unplugged the rca cables from the amp!
I’m running pac amppro ch41 using my factory radio and audicontrol dsp amp
Could it be the pac amppro or amp fault? Help plz
hey peter, how are you measuring the sweeps? averaging 4 or 8 sweeps? 4 on left ear and 4 on right ear? or other combinations?
Great explanations.
I'm still waffling on whether or not to try out a Helix V12 in a 2016 740i. If it's not enough it's a big waste of $ to chuck and switch to DSP / A/B.
Not enough in what way? Output? For components it’s very capable. For sub(s) i’d use a separate monoblock.
@@pssound9749 how about for the HK or replacement driver in the underseat location?
@@ccvideotech get a 2-4ohm aftermarket upgrade and it’s absolutely fine. Some of the HK ones are 8ohm.
@@pssound9749 I was thinking a small enclosure sub on a monoblock (processed through the V12) at the front of the passenger foot well to fill out the lower octaves a bit as the trunk is sealed and I'm not going to drive around with the rear armrest down just to get base.
Do you have a driver recommendation for that. Or, do you think the right underseat driver can cover "enough"?
Chef master for car audio 🤫😜🤩🤩🧞♂️🧞♂️🧞♂️
Why don't you ever use morel drivers? If u have how's your experience with them?
Another great video, wish you could show us more tuning. Do you measure from one position at drivers seat? Also show us time alignment and level matching.👍🏻
It’s secret info, nobody wants to give that info away for free.
He measures from wherever the listening position will be.
@@chokboywonda yea but some people take measurements from 3 different positions at headrest, left ear, right ear, center, then sum all 3
I would like to get answers for many questions too, but sadly it’s not as simple.
Anything more than what’s already been shared in all the tuning videos on CZcams is gonna be part of a training program for those who really want to take their caraudio skills to another level.
@@pssound9749 does than mean you'll be doing a training series via Patron or something separate?
I would be happy to know how you measure with the microphone. Do you move the micro slowly from ear to ear? What micro equipment do you use? How do you work with the delay? Do you use time accoustic measurement in REW?

@@pssound9749 Fine, where can i get detail information about the training programm?
Steg sdsp68 vs Alpine pxe 0850X?
Steg mss es mejor o igual que focal utopía?
You mentioned feeling the kick from the mid bass, its weird that some cars you can feel it and others you can't. I've seen cars with almost identical responses from 20 to 20k and both felt so different. What cause that?
Any car can measure the same with great amount of tuning and EQ work, but as you say they sound different.
1. Midbass drivers are in optimal locations and application for the driver’s T/S specs.
2. Transient response of speakers
3. Car size & rigidity
These things are all variables and difficult to tell the formula.
I would really appreciate a tutorial about measurement technique. Averaged static measurements or moving microphone? With driver in position or without? Please share some info! 🤩
Hi, anything more in-depth was shared on www.patreon.com/pssound. Week 22. Topic, shared 31/05/2021.
Peter, the first thing you say in the Patreon video you referred to is “I cannot reveal my measuring technique”. I find this very disappointing when you ask me to join your Patreon community to find out. If you do not want to share this info, please do not trick people to be your Patreon.
@@leoeskelinen1867 I didn’t say everything would be shared on Patreon, but at least quite many things are cleared up in that video, your questions too, let alone all the other videos in the Tuning playlist that i’ve shared in the last years. Show me one more professional in the trade who shares more information for free, i want to follow that person too! 👍

There is this style to install tweeters in a-pilar and aim them straight to each other. Is it usable or not?
I would keep tweeter within 20-40degree on-axis. Facing each other is really not working for me, especially on driver’s side.
What would you recommend for me to do to get a higher response out of my sub? The measurements are very narrow it seems to only play between 40 and 60hz it is a very high peak it looks like a bell curve. It's in a custom box built to spec tuned to 33hz. I cannot get a good blend with my midbass with such narrow bandwidth. Do you think going sealed will help? The sub is 12" in a 2ish cubic foot box. I'd like to get a response up to 80hz if possible for midbass blending.
I think you're already thinking on the right track. A new box will likely go a long way. Personally I've always preferred sealed vs ported.
Also... (1) check your crossovers and make sure you don't have two turned on by accident or something like that. (2) move the mic around and take some more measurements to see if it's just a positioning issue. If moving the mic changes your measurements, return it to listening position and move your subs (if able).
Easiest way to test it quickly is just block reflexport airtight. Then you can check if output changed to hoped direction. But some subs won't work in sealed enclosure. So test carefully, you might find your sub excursion limits even in low listening levels.
@@ilkkak3065 I actually tried that already and the response changed but in the wrong direction. It wasn't exactly air tight I just stuffed the ports with towels real quick to see if anything happens. I'll try a more air tight seal and measure again. The sub I run can be ran ported or sealed according to manufacturer specs. It's a low end FI audio the xv3
You may want to sign up for Patreon and check the weekly topic where we talk about good sub bass in a car. It’s more complex than just ported/sealed. Plenty to learn there.
Hi Peter,
how does this sub works in sealed for metal / rock?
I have for a long time Phase evolution Aliante 12 and I am considering some change. Or what would you use as a sub in small car for metal / rock mainly?
Thanks
Aliante is hard to beat in a sealed box as it’s so accurate and controlled what you need for rock. W3 is great in sealed too.
@@pssound9749 Hmm so Aliante for more years to come :) Thanks
@@kiklop8362 get another one and run 2, more fun! 😃
@@pssound9749 Oh cmon, I have second one stored under my bed :). But there is not much space in fiesta.
How that tweeter sounds? Could You compare IT to the accuton c30
It’s a good tweeter, but nothing mind-blowing. Not much point to compare it to the C30AM.
@@pssound9749 do from those two You will chose c30 ? Im looking for something to spare with my z studio 100f midrange and 20 cm gorlich wf
What do You think about this ? Mss-1 with those stuff
@@MrTorque3 MSS-1 is so well priced, that you shouldn’t even look for validation from anyone. Just buy it and test it then.
