Thank you very much for your contribution and time, I found this video and discovered many more. I am about to start putting together a 3-way active system + subwoofer with DSP ALPINE and the truth is that you gave me a great help.

These videos are so helpful. A lot of really useful information, explained better than pretty much anyone else I've seen on this subject. I knew around 75% of it, but you got at the fuzzy points that other people don't really explain. At the moment I'm using time alignment and active crossovers from my headunit, sounds ok, but your videos make me feel a lot more confident about not putting of a proper dsp for much longer. Thanks so much for taking the time to do this

Such a great video. Thank you for this. It's very hard to find in depth videos like this. Please keep this up!!

Very helpful, I wish andy would do videos like this because even though the information he puts out is mostly helpful, alot still comes across very high level and assumes everyone has a rock solid foundation in the basic concepts.

Love the video! Here’s why: you clearly know what you’re talking about, you were able to explain something highly technical with visual aids only(“no numbers” as you had warned), you got straight to the point, and lastly you used an honest and easily searchable title. Great work 💯 Content creators like yourself and videos like this are why I keep coming back to KZread for my random and not-so-random educational needs. 🙌 P.S. your hit rate for likes vs views on this video is impressive👌

Oh man, it's been 2 years? Wow,time flies...

Thank you very much it really helped me understand better the process of troubleshooting ❤

Thank you, that was helpful. The key information I was looking for was how to adjust the drivers when crossing them over to minimize phase problems. In addition to matching the slopes, I would adjust the gain of one of the drivers so the graph looks as flat as possible in the crossover region?

Well explained!

This actually helped me out so much thank you

Perfect video. Five star. I hope for more. 🙂 do you use stereo or mono pink noise when measuring two speakers left and right together?

@@RAW-CAt I have been using mono periodic pink noise so far and I thought it gave me the best results possible. However, you probably know that some professionals use uncorrelated pn for the speaker pair. If you check Peter's RTA videos, he utilizes uncorrelated as well. It is obvious when he plays the midbass pair together, they sum +3db (with correlated you get +6db because of phase). Now the question, do we match our midbass pair to the subwoofer with their 3db sum or 6db sum? It makes a big differences indeed. Most people think of uncorrelated pink noise as the pn which sounds like rain, because it has left and right 180° out of phase, but then this would give you a perfect comb filtering in the bass area. Therefore I learnt that uncorrelated can be out of phase to even lesser degree, and then the comb filtering wont be so obvious and it is possible to measure the bass area as well! Check the uncorrelated pink noise file which is provided by AudiotechFischer for their RTA, and compare it to the usual tesing uncorrelated pink noise which sounds like "rain". They are both uncorrelated, yet very different. Also, if your uncorrelated pn shows flat response with the pair, but correlated shows peak and you adjust it, then your uncorrelated wont be flat anymore. When I play my midrange speakers with correlated together, they sum 6 db up to 200-300Hz, but then they sum +3db (tweeters also) because the reflections wont allow the perfect summation despite the correct TA. Again, do I cut the bass area, or raise the upper frequencies to make correlated flat? Either way, the uncorrelated wont be flat anymore and the system will sound much brigter. Just an idea I have been struggling with lately. 🤷🏼‍♂

Great work...

This might be a basic question but when you find where the null/cancellation is coming from (in your first 74hz example, that'd be the rear window), why do you take half the wavelength if the wave is traveling from the speaker to the rear window and then bouncing back to your ear? I would think that's 1/2 + 1/2 = 1 full wavelength? What am I not knowing? Thank you so much.

I am interested in all pass filter correction.

Could you do me a big favor and send me some of the comparison REW files between the door mounted mids compared to the kick mounted mids? It would be a big help on my end =)

Can a phase issue could be the reason why I'm feeling I don't have any stereo image on my system... It sound good, it's clear and the soundstage is right in front on me, but everything seems to me mono with very little stereo separation.

What you are describing to me it sounds like psychoacoustics. A lot of people all their lifes listened to a car with no EQ and no TA where the sound is everywhere coming from all directions (including rear speakers) and after a proper tune, the center get's focused and it sounds by comparison as mono🤷🏻‍♂️ That's just my guess.

@@RAW-CAt I don't think so... I have use pretty good bookshelf on my computer and they have phenomenal imaging, not to mention my wife's mazda that have the stock audio system with well placed tweeters and it has a very good soundstage that comes from the front while keeping an impressive stereo imaging.There is something wrong with my system and I can't pinpoint what it is.

@richie.rich98

If you have no stereo imaging at all, you most likely have a timing issue between left and right drivers. It could also be improper measuring technique while tuning, you can measure a driver and get a linear response but that doesn't matter if your technique is incorrect because the response you're seeing is from that given location where you place your mic. As soon as you move your head you'll hear a completely different image that what you tuned.

Someone using 180 phase on tweeter only, why? have any specific reason

You look for better summation. If tweeters out of phase electrically gives a better sum, you use that.
