[QUOTE="Timo Beckman, post: 101148, member: 1173"] Re: End-Fire Array with All Pass So first : the mic at the back of the array was about less then a meter away from the back sub so if i had had more room the mic at the back would/should have been roughly at the same distance from the back sub as the front mic from the front subs was . This means that the cancels at the back were deeper but i'm just guessing on that . With the all-pass thing you have more control over the cancels in the back by playing around with the 2nd and 3rd row of subs in the picture (S2 and S3) . So if you're on a small time window for the alignment use delay (maybe along with allpass filters so a mix of both have not tried that). If given enough time and the noise pollution police eager to give you a fine for to much level breathing down your neck (10.000 euro's in the Amsterdam city centre for example) it can give you just enough control to keep them in there offices (that'll be the day;-) @frank thanx and yes it was a lot of work but a very interesting experiment . @tim i'm just curious (and rocking all the time if i get the chance) [/QUOTE]
