I heard that you should try to stay away from square boxes because the frequencies could just cancel out or something like that. Is there any truth to that at all, does anyone know what im talking about? I heard that you should try to get a slanted box.

From what I've read it doesn't make any difference unless the box is huge.

so a box with .88 cu. ft per chamber won't matter

Ok here is what it is, you don't want the peice the speakers are mounted on and the back of the box running the exact same way. You want to slant one of them so any sound waves aren't deflected directly back at the sub. (creating cancelation)

just add a bit of poly-fill.

Wouldn't cancellation only occur if the distance from the front baffle board to the rear and back again was 1/2 of a wavelength (or close) which would make the sound waves out of phase? If that's the case then it really doesn't matter for subs cause the wavelength of a 100Hz tone is 11.3 feet so the distance from the front to rear would have to be almost 3 feet. I think it's more relevant to smaller speakers.
