who wants AP?

anyone wanna build an AP enclosure?

I dont really see any benefits to using it honestly.

looks to me like maybe theres a space benefit, if you put the membrane behind the baskets of the subs instead of having a box? i dont know it was a little confusing to me but i didnt read into it to deeply

Sounds as if it's all sq oriented without any spl. I know I don't listen to jazz and top 40 as it recommends lol.

it actually does what the enclosure is SUPPOSED to do .... it tames the impedance curve of the sub. That means you get more uniform power output from your amplifier over the range. Richard Clark had 2 15's in AP enclosures like 15 years ago, the car was designed to be in the 140 dB range.
