The delay on each speaker is in inches and can only adjust +/- 2" at a time. The sub is right behind me, reg cab truck, and the sub has no t/a adjusment. Should i just get a tape measure out and try setting it that way?
Probably what I'll do next seeing as nothing has really worked for me.
Since you have delay in distance you need to start with all the channels at the max setting= no delay. You don't start with zero inches. Also since the sub is not the farthest away you need to start with the pass side midbass(which prob is the farthest) Oh...If the sub doesn't have delay then this won't work for you. You could just do the measurement thing and it should help. Then just swap phase on the sub til it sounds best.

Re: Precision time alignment using only noise tracks and your ears
Hi,
I can't seem to locate or identify the doppler or sound as I increase delay. I know how to tune a guitar so I am familiar with the doppler effect but I just can't seem to find it within the pink noise. Does anybody have any advise or tricks... or ANYTHING that will help me identify the point at which the both speakers are time aligned!! Thanks for any help. I must have listened for an hour trying to "spot" a pattern and I focused in on the lows and highs within the pink noise.

Hi BG
The answer is on the post above you ��
Based on my method:
I always isolate the freq between two driver within the same freq
I.e. MB 250 - 500 and MR 250 - 500
I found it easier to hear the noise change
Happy trying ��
Re: Precision time alignment using only noise tracks and your ears
So in reading all 9 pages I come to the conclusion that I need to set my sub to max distance (300cm) and go down from there. It goes from 30cm all the way to 300cm. Does that make sense?

If your sub is the furthest speaker from your listening position, then yes. Setting it to 300cm would be the zero delay setting. Remember to set all of your speakers to 300cm and work "backwards" while not touching the sub delay.

Re: Precision time alignment using only noise tracks and your ears
Has anyone with ta that measures in distance instead of time had better luck by setting everything to halfway(range from 0-132/setting to 66) before starting. I kept having the problem where the doppler effect would continue to decrease though the entire range of ta adjustment. For example, when I would be adjusting my tweeter I would start to increase delay and the pitch would start to fall. The problem is that it would continue to fall until I got to full delay(there would be no peak or trough). I concluded that the peaks were at the ends of the adjustment extremes. By starting with everything in the middle I was able to hear definite peaks or troughs. I hope i'm not the only one with this problem.

I wasn't really able to use this threads method for the mid to sub delay either. That's why I just use music.
After countless hours of trying pink/white noise I decided to use music instead. 1/2 an hour later i'm . The method itself is really good though.

Did you use one mic position or average several positions?

WOW!!!!! I really don't know what else to say...
Spent a little time setting the delay on my mid construction install. The results were so amazing I spent the entire night playing all my favorite tracks just to see what I have been missing all these years. Already this is the best sounding system I have built to date. I wish I had taken the time to learn more about the time alignment years ago when I picked up the Alpine in the first place.
Thank you OP and all others for the helpful information.

Good job. Everybody knows a vehicle interior is a bad environment for a sound system, but few realize just how bad it is. All you've done is remove some of those negative effects.
It's not about buying the best equipment, it's about getting the most out of it.
I've learned a lot from you on DIYMA, Erin, and take it as a compliment that you would post this in my thread. However, the very point of my method is to eliminate the microphone from time delay tuning, and to use your ears instead.
