Alpine F#1 w/ PXI-H990. It does have auto TA but I never really trust those, I always prefer to do it by ear as much as I can and I usually find better results that way.What kind of deck are you using?
I use a Pioneer 860mp and it helps to do the sub alignment.
But the deck has the toys(but not all of them).
From what I heard, it can definitely put the bass and staging up front and it makes sense. With the subs being so far away and playing at the same time as the result speaker, it's quite a lag behind so the bass notes are not reaching you at the same time but rather later on.Would T/A help you get away w/ a higher LP point, while still keeping the bass up front?
Awesome thanks! I have my mid-bass playing down to 60 hz which definitely helped. Another tutorial I found was http://www.diymobileaudio.com/forum...-realized-easy-way-calculate-time-delays.html for those interested1. Measure distance from forehead to all speakers in meters (0.00 accuracy is more than enough).
2. Distance of farthest speaker (usually your sub) - distance of speaker to adjust
3. Divide by 343
4. Multiply by 1000
5. Answer is time delay in milisec
6. Listen and make small adjustments, I tend to delay the fronts/center a bit more (all by the same amount) than the math says to give the illusion of "bass up front." Also helps to have your midbass up front playing as low as possible and sub low passed at 24db/oct below 100hz (I tend to set it no higher than 75Hz).
Hope that helps.
Assuming the sub is the furthest speaker from your listening position, you'll want to time delay everything ELSE, not the sub...
One other interesting thing to consider is from which point do you measure the subwoofer distance from if the woofer is facing the back of the car?
1) from the cone to driver
2) from the cone to back of trunk, and then from back of trunk to driver
I'm thinking #2 since that's the path that the waves would follow.
How so?then doesn't it mean that the above 2 statements are totally contrasting each other???
one says delay the sub , and the other says DO NOT.
please explain this in detail
If the sub is your reference, not delayed, the next furthest driver from the listener would be delayed by the difference in path lengths. If your sub is 7 feet from your head, and your right mid-bass is 4 feet from your head, your right mid-bass time delay would be equivalent of 3 feet of time delay, translated to milliseconds. Your left tweeter could be 2 feet away from your head and 5 feet of time delay. That way, the waves from sub travelling 7 feet arrive at the same time as right mid-bass that's 4 feet away and was "held up by 3 feet," and your left tweeter that's 2 feet away and was "help up by 5 feet."wait a moment. so you say the sub must be at zero..
then how do the 2 scenarios matter? anyways we are not delaying the subs.
sorry for asking this, i didnt get it..
