hollywood93 Posted September 24, 2010 Report Posted September 24, 2010 Hey I am wanting to make a small (2 12's) bandpass box. Like 2 Rockford Fosgate P3's or something like that. But I have no idea how to calculate the port. Do I just use the 12-16 square inch per cu. ft like a regular ported box or something else? thanks for the input.

bassl0va Posted September 24, 2010 Report Posted September 24, 2010 yep, just go for 14sq"s per cube. Bandpasses are quite specific though, read up on it quite a bit first.

So if the sealed part is 14 H x 30 W x 20 D what would the front port section be roughly ?
