Posted January 20, 201312 yr Hey all. Im looking for a design for 2 12 Sa's in my PT. My max dimensions are 39 W x 15 D x 20 H.i will be running them off of a saz 3500. Im looking for a cross between daily and burp if there is such a thing.Ive been told in the PT to run port up subs up with slot port inbetween the subs. I had someone making a design with cut sheets flake on me and I have to have a design by Monday when i have a shop to build in. I know this is asking a lot but if anyone can help me out it would be appreciated.the design can be basic as i dont have much room to work with. I just need cut sheet list and I should be set.Tuning should be right around 33-35 hz. and box should be right around 3.7 cubes after disp. (overpowering subs) .18 disp per sub.I appreciate any help i can get. If im out of line asking for something lie this I apologize.Thanks in advance!
January 20, 201312 yr Are you running the amp at 1 ohm? If so you will have to be very conservative with the gain or the subs won't last very long. I'm sure that you have heard that they are underrated and can take a lot of power, but 3X RMS is far too much.

January 20, 201312 yr Author Yes, i am being very conservative with the subs. And thanks for catching my mistake on the disp.
January 20, 201312 yr It wasn't me who dropped the ball I hope. There's always a possibility that you'll run into trouble with a center port. The port area or tuning may have to be far from optimal to fit the port length inside 20" of height.
January 22, 201312 yr Subs up port back worked well in my PT. Got me a 154.x with a single 18" that way.
January 23, 201312 yr Author Bassahaulic, I would love to pick your brain a bit on PT builds. Do you have any pics? Build logs?
