[QUOTE="Slappin709, post: 6581660, member: 618097"] I'm thinking about how to design my next box. It will be for 4 12's. I know the sub choice is disappointing but I'm a high school student with little money, just trying to have fun. I've had a single 10" before but it wasn't enough. The subs will be Dual DS12's, just shitty single 4 ohm standard drivers. I was thinking about 7 cubes(1.75 per sub) at 34hz. The plan is subs up, port back, using a 12" sonotube(~113" port area). It will be going in a late 90's Escort wagon. They will be ran off of a Hifonics Brutus BXI1210D @ 1ohm. I'm having problems trying to calculate the box volume/tuning. I don't understand how to tune regarding including or not including the displacements of the bracing, subs and the port. If I'm looking for 7cubes with a final tuning of 34hz how would I go about getting that? Thanks! [/QUOTE]
