Subwoofer box shape?

Does it matter what shape your sub enclosure is in as long as it's the correct volume? For example, will a square box sound different than a rectangular box of the same internal volume? Or a triangle shape for that matter? What are the effects on sound quality, loudness, etc., if any at all? I am asking because I am going to build a sealed enclosure for a 10" sub requiring 1.0 cubic ft. of air space, and would like to shape the box to best suit my needs of utilizing trunk space. Also, when the manufacturer gives you the recommended internal volume, does that factor in the displacement of the sub itself? Or should I add the extra volume to compensate? Thanks to anybody who can help with these retarded questions. This will be the first box I have attempted to build with exact specs. All the other ones I just threw together without any attention to allowances or detail. Thanks again, sorry for the long post.

mmm yes this i found out the hard way, i have a single cab hilux (tacoma) with 2 12inch s-type Alpine subs and what %$#@ it was to get them in.

and i agree that box shape does make a difference no matter what the specs are. And NEVER build a square box it just doesnt work.

OK, this has been covered already but box shape does matter.  You never want to have a cube box because as stated above, this creates standing waves.  When designing a box try to think of it this way, you want the sound waves that have come from the back of the sub to deflect off the enclosure walls and come back to the cone at different times.  You do not want a cube box, cause then the sound waves have the same distance to travel to get to the walls and back to the sub in every direction, so they all hit the back of the cone at the same time.  Where as a long rectangular box, with the sub placed away from the center, creates much larger differences in the distance sound waves must travel to and back from to hit the cone again, so they hit the cone at different times.  This will make the sub sound better.

And I can vouch for the anti-cube enclosure theory, a book at borders talks about it.  Oh and can anyone give me more specific information on why not to have your subwoofer too close to a wall of the enclosure, cause im in the middle of a fiberglass project where the enclosure is molded into the wheel well, and the sub would be very close to hitting the bottom of the enclosure.
