Feel like I’ve been in the mind of a master….. thanks again Peter sand crew.
I've always liked my systems to sound clean but had no idea the level of knowledge it takes. Since finding your channel you have single handedly taught me more than I knew from over 10 years of "novice, boom boom" car audio. I am now running a 3 way with 5.25 Focals in the dash, 2'' CDT widebands in the A pillars (soon to be tweeters), 6x9 CDT midbass under the front seats in sealed birch boxes (plans for IB midbass), a 10'' level 3 DC audio sub in a ported center console birch box (plans for an AE 15'' IBAU) and a dayton 408 dsp. i know the DSP is shit but it was my first and cheap so oh well it gave me time to get used to tuning with REW. I now have a Helix M four DSP I'm installing soon and can't wait to get tuning. Thanks so much for your honesty, all you've shared and continue to share.
I really hope people realize the level of knowledge and skill you consistently provide here on your TH-cam channel.
The guru making it clear door location is not best for midbass, but doors are easy for most install shops
Only if every installer everywhere in the world had the technical knowledge and passion to do mid bass installations like peter does , to the last detail of perfection.
The car audio world would be at a different level if every installer had his vision.
Peter you can't make a boring video. Like Mr Bell said, you are the car audio Master. Thank you for another great video.
So nice to see the wizardry behind the sound. And oh it sounds sooo damn good that I’m obsessed with it. Sometimes I escape from home and just sit in the car even if it’s for 5 minutes to listen to 1 song 😂 definitely more powerful amps for front stage coming and a play with different subs 👍🙏🔥🔥🔥🔥🔥
Your phone doesn’t send enough level, the system was way louder with the iPad! 😃
I always find something useful in your videos 😜😎
Looking forward to your instructional video release for tuning!
Really well explained video and this was the one that makes all the pieces falling into place. I have struggled for quite long with my dsp tuning and now I realize that the best way for me is to upgrade my 2-way system (that i thought should be enough) into a 3-way system with a pair of midrange speaker as well. I have almost the exact same cancelations in my VW Polo and my midbase drivers also have those dips around 300Hz-600Hz. Now it´s time for a A-pillar project and then I will hope that some of the issues will dissapear.
Thank you for the explanation, Im going to re-watch this two more times at least. Very well explained.
Thank you for taking the time and posting this content Peter. This was very informative and helped me a lot!
Peter, Brett from Alaska,. I love the comment you made when you pulled the Rockford fosgate T36.5s out. You have help me understand a drivers finction and determine whats best for the bugdaet and application. Those retail for $650-700 us dollars. I have them and paid half that. They are being reused in my sq build right now in the doors.
I dont teust the shops here to tune, if i ask them questions like your video is about i get that look.
Always love the videos and thinking time to step it up and buy all at tuning equipment i need to do it myself.
The things I learn from your videos! At 12 mins 20 the dips etc. Thank you for these in depth explanations Peter. I have recently fitted a Key 200.4 (not a proper user settable DSP I know) but what it has done for the active front stage in my car is amazing. All those things I always read and heard about staging and placement etc- every track sounds new. Can only imagine what the real systems you build sound like 🤩😎
Yeah, they’re alright! 😃😂🔊🔊
@pssound9749 as you said that the reason the sub can't fill in the driver side null at around 60 hz due to the location of the sub and the midwoofer, what if the sub was moved up closer like in the rear seat instead of the trunk, would the sub play higher and fill in that null?.
Thank you, Peter, these videos have helped greatly since I have started tuning with dsp... You are a wealth of knowledge...
Thanks Peter always a great content … big up !
I've really grown fond of this channel. Great work and excellent presentation... Well done 👍
Brill content as ever Peter.
Laughed at your bang on comment about 2k to 5k its 200 percent the fatigue and harsh range even 2.5 - 8k for my ears depending on volume. Mid bass burns voice coils easily at those frequency too if driven hard only even mild clipping, perhaps because the speaker doesn't move much the voice coil has a meltdown. This is just me learning over the years blasting it too loud 😂
learned alot ~ I might consider patreon training course.
Thank you for making another tuning video!
Peter, thank you! I can't wait until you make your course available. Will it be coming soon?
Noice!
This car and system would suit you very well! 😎🔊🔊
Thanks
Great video Peter! could you do a video about the different dsp's, brands, their controllers and what they can do? also a video about the zapco R-IV iPhone controller and what it does? :D thank you very much!
R-IV is pointless, so no need for video! 😃
For the rest i need sponsors.
Also, because I'm in America, I have to say it...sounds like you love CHEWNING 🤣😂🤣😂 🤘🇺🇲
"If you are good at something, don't do it for free!!"
Great Video Pete! Just a suggestion, try an all pass filter on that driver side midbass in that 60 to 80 range. I know you know the outcome of all pass, it will change the phase at just that frequency and "may" eliminate the cancellation. you can watch it in rew what it does..just activating and bypassing...back and forth
Yeah, a null point in the cabin can never be eliminated.
@@pssound9749 Exactly.. You can deal with allpass filters when cancellation happens between particular drivers. Not drivers alone.
Awesome vid. Can I ask what mic method you use? Like moving mic from ear to ear ect??
I explained in the video where i stand about sharing more about tuning.
This information is given in the video ;)
Nice and very informational video Peter. Installing and location off the drivers are crucial, but it looked to me that the midranges and tweeters were more “tunable” then some other drivers in other videos you posted. Am I right or am I imagining that? Or is this because of the acoustics of the car itself maybe? I’m especially curious of your opinion on the sound quality off the tweeters, because I know those are not the most expensive tweeters because I have a pair of them which I never built in a car but only sound tested them in my home test setup.
I was also surprised how good they were even without any running time. Price doesn’t always reflect quality, some expensive stuff is just disappointing, but this one wasn’t at all! 🔊🔊
@@pssound9749 thanks for your reaction Peter. I agree, they are very revealing without being harsh. Very good price quality!
👍👍👍
Hi Peter, thanks for your informative vids. They are of great help. One question: the crossover points of the midrange: 300Hz en 3Khz?
200/4000.
@@pssound9749 thanks
Thanks for this Pete. Just one question, what banding are you doing the work in? Is it 1/12 or 1/24, not sure if you mentioned it in this video? Thanks
It’s measured in 1/48th and tuned in 1/12th.
Hi Peter. I got a Passat B8 2015 model estate with a Dynaudio system. I saw on your website shop you have a helix DSMI25 most adaptor. Is that device compatible with what I need or please advise me on what should I buy. Thanks a lot
Hi
Helix SDMI has been out of production for almost 2years now and they still don’t have a due day when they can supply it again, so many people & businesses are in a poor situation to do MOST25 integration. You can still check the Audison BitDMI or alternatives from Mobridge or NAV-TV.
what measuring technique are you using? depending on how one measures, the tweeter measurements can vary greatly. Like i can come and measure this car using 4 sweeps but my measuring technique and locations are diff than yours. This could yield vastly diff respsonse curves. Just wondering how you do it? great vid btw!
Years and years ago I have read in a magazine that you should always tune / eq the sound as little as possible because adding filters, 24db slope lowpass, equalizing the channel and sorts of that will introduce all kinds of phase problems depending on which tone is played and processed at a given time. Is that still an issue with the new dsp's ?
The issue is not the DSP. DSP is a tool for room correction. The real issue is the environment. Once you put speakers in different locations in a car, the cabin has such drastic effect on the response of the speakers, that it’s impossible to get decent results without being able to correct the differences in response, time & phase between speakers.
Those who said that in a magazine have no clue about car acoustics. Their theory may work in home environment, but even over there you need active, passive or both room corrections.
In a car in order to achieve magic, you need a fully active system and a very capable tuner. Once you hear a system like we usually deliver, there’s no way back! 🔊🔊
Peter do you use the measurement tool of REW or its RTA , Im currently using REW to measure but not with the RTA, just doing a sweep from 20hz to 20khz that REW provides in the software.
In a car you really want to use the RTA feature. If you go to the Tuning playlist, then you find many videos there related tuning. Also, check the description in the 1st video of that playlist where you find links to MiniDSP website for proper guide.
@@pssound9749 .. I will do that now for sure. Didnt know the REW RTA allowed to take still images of the speaker response like the ones you showed in the video. Ive only used it for home applications. And for that we just use the sweep tool.
@@pssound9749 Also.. do you know if I sign ip for Patreon I will find information kn how to use the Helix dsp software? I know the basics but want to get more advanced.
@@canillocanillo3371 we only share RTA evaluations, but there’s a lot you can learn from that too, plus all the other behind the scene posts & weekly topics. 🤘🔊🔊
Salve, bellisimi i tuoi video peccato che nn riesco sempre a tradurli in italiano ma molto istruttivo, ho una domanda,visto che uso anche io rew per a tarare il mio impianto auto , sulla totale delle 2 risposte tw+wf avere +4 db all incrocio è normale a quelle frequenze è possibile raggiungere anche +6db all incrocio? Intendo wf e tw usando un 2 vie in auto ?
O dipende dal filtro che viene utilizzato Se LR o butterwhort?
Hello Peter, are you using Rew to tune?
Yes. Check out the Tuning playlist, you’ll see more RTA videos there, which maybe useful for you. 😉🔊🔊
How much for the training? :)
How much would you spend on learning a trade?
@@pssound9749 That depends :) would it be online?
@@kiklop8362 yes as it’s almost impossible to travel these days.
What sounds do you use when you tune
I had one of those TW5's in my truck. Same issue, that 60-70 htz dip really made it struggle with midbass transition and coupling. Always pissed me off. Couldn't ever get it do what I wanted it to do, no matter what I did. Ended up changing the sub out for 2 10" Audison woofers and that problem disappeared completely. Being a JL Audio dealer and working with those many times, I've found this problem with most of their woofers. However the 10TW3 woofers have changed that a lot, they seemed to have filled that gap with that newer design, and I don't have that coupling issue with those...at all anymore.
Hard to believe that the dip disappeared completely when it’s location and cabin size related.
@@pssound9749 most of the JL Audio woofers I sell have that dip, even the TW3's at some point depending on the car and location...and those have MUCH better midbass transition and coupling capability.
But yes it disappeared because I changed woofer brands. As you know woofers sound different and perform differently!
@@bmuenter 60Hz doesn’t just disappear in a sealed box when measured from nearfield, physically impossible.
@@pssound9749 still upset because you can't figure out to integrate rear speakers in a car correctly huh? Telephone tough guy huh? #keyboardwarrior
@@bmuenter out of two of us i’m not the one hiding behind a fake name.
I stated what’s a fact. Measure a sub in nearfield. If both (let’s say for instance JL and your Audison) play 30-40-50-60-70-80Hz etc in nearfield clean and linear, then you put them in the trunk, then how can one of them have a null at 60Hz upfront from the same location and not the other?
Do you use sweeps for measuring or constant pink noise?
Pink noise.
@@pssound9749 I get very different graphs with PN and log sweeps in REW, but EQing with sweeps gives very better results, is there anything I'm missing out, can you help me out a bit.
@@wolfpowerracing2759 you have to watch the videos in the Tuning playlist.
@24:28 so what is the difference between flat and linear? I still don't understand the difference. It looks flat to me.
Flat is when response is ruler 📏 flat, which usually sounds weak below 250Hz for our ears. It’s the lower the frequency, the less sensitive our ears are. In order to hear all frequencies balanced, we need a linear rise in the frequency response of the system below 250Hz. 3dB/octave rise is usually a good starting point.
Check out the videos in the Tuning playlist to get better idea of it.
@@pssound9749 Thanks :)
