Guys,
Another question.
Box shape for sub.
Never build a cube shaped box, which is the absolute worst enemy of a smooth frequency response curve

Is it so critical? I read on many forums that box shape is not so important and I was going to make 15X15X15.

That is debatable... On the one hand, bulding a cubic box, all first order standing waves will coincide and have a maximal effect. On the other hand, if you make your box a cube with the side 15 inch, the first standing wave will occur at ~450 Hz. If this is a sub, you will have filtered out this frequency properly anyway.
Using another ratio will undoubtedly lower one of the three first standing wave frequencies and make the problem worse.

I agree. However, for a "bass module" that will reach above the midbass, shape is a consideration.
Im totally with Sean on sonosubs, Ive made one and I am really happy with the results. You can check out my webpage for some pics and the link below gives heaps of great examples.
