Looking for some sub box design advice. I just picked up an Alpine Type S 10" sub and am looking to build a 1ft³ sealed box. In the following image I have drawn up 4 different designs and was wondering if any of the designs would be better then the other. It others words, which design would be the best design?

The one that fits in the car the best is the best design.

Thanks. All four will fit fine as it is going in a trunk, I am just curious if there were advantages with either a slanted face of flat face.

not really. a box is a box, long as the airspace is the same, it'll work well.

i disagree, a box isnt just a box, non braced boxes of the same volume will have definite different sound characterists, boxes with the woofer mounted off center can help to reduce cancellation and standing waves in the box, as will a box with a slightly slanted baffle.

How do you get a standing wave if a parallel wall is only 15 inches away at most, yet the wavelength is well over 5 feet?

u glue random peices of wood (small peices) to the parallel wall or even all the walls inside the box.
