Will This Work Good?

This box is for 2x 15" Fi SSD's i want it to slam. Going to be pushing atleast 800watts to each sub.

Box is as follows:

9.15 cu ft after sub displacement but before port.

Wedge box 48" wide, 26" tall, 20" bottom depth, 12" top depth.

4x 3" diameter pvc tubing cut to tune to 35 hz. which will be mounted at the top of the box coming to 130 cu inches of port area.

Heres my first google sketchup attempt. This is how i plan for it to look.

(4) 3" ports is only 28" of port area. Going to get a lot of port noise. (4) 3" ports is no where near enough for two of those 15" drivers.

(4) 4" aero ports will work in that box. They would need to be 12" long.

I would even double the front baffle (side the subs mount to) making it 1.5" thick.

Box with 1.5" thick front would be 8.25 ft^3 tuned to 35 Hz.

edit - If you don't use aero ports, then use (5) 4" pieces of PVC, each 14" long.

Still is 8.1 ft^3 tuned to 35 Hz using a 1.5" thick front wall.

Vent isn't even close.

I'd use 80sq"

Lol note the 130 CU inch... you want square inches or port, not cubic inches
