lol, I should really ask what application a sub is for b4 I spout off!!!

Usually, a 40hz ported (with protection below that) for pa will get you awesome results, assuming you can get flatly down to 40hz anyway).

Jbl 4508 and 4509 dual 15" cab just happens to be tuned to 40hz.

I think bandpass can work well for pa.

Yep Maxo, I agree with the SS15 as a good choice given your parameters.

SS15 build
