I am looking for some help with a box for a single american bass xfl 12" with two exteral areo ports the ports are 8inches long and 4" around

What do you need?

You don't build a box around the ports, you build the box, and port, to the sub.

Please don't say you have two 4" aero ports 8" long and thats all you can use.

I'm going to guess at 2 cubes for 1 12 and a 4inch diameter 8 long is roughly 35hz. If you do another it's gonna be very high tuned, spl for sure. If you're going with two they will have to be longer

[akronjay]

just had the ports and subs sitting arond and was just seeing if i could put them to use,just one single sub.so 2 cf not really going for spl

Why not

Single subs perform well in some cars, and in right box with good power can outperform many other setup

Ive seen 2x p312 on 1500rms only get 128db and the set cost that bloke a small fortune, and there are many out there that are the same, no educated

Why not what?
