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 ****** 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!

How much are those Duals?

Like $60 CDN a piece haha. Not looking for good numbers clearly haha. There isn't even a comp in my province that I know of. Just a fun building project moreless.

Wow I totallly missed that. I guess i'll decide when the time comes.

Do you know the answer to the box question?

Do you know the answer to the box question?Well, if you get the PG's then the box you want will be a bit big for those. Also you didn't list your maximum dimensions. That's rule #1 when fishing for a box design.

For volume related to tuning you need to subtract bracing, sub displacement, and the space the port takes up.
