Hey all

Basically, i have a ts-w307d4 pioneer champion subwoofer and im sick of the box it came with. I cant hear the low frequency bass, and the box design is designed to save space, and not enhance bass.

I have decided to buy another of the exact same sub, and build a box specific for these subs with a port. However the problem is the box dimensions, as the box has to be built according to the sub specs. I've searched as much as i could, with no luck.

The pioneer website recomendations for this sub are
24 - 40.6 (or 40.9 i dont remember) litres
0.85cu ft to 1.75cu ft

Now my questions are, where the hell do i found out a good dimension that will enhance the bass according to these spec subs.
Any help will be appreciated as im pretty much completely math/dimension noob.

Thanks fellas, George.
