I talked to Nick at Incriminator Audio (Subwoofer Maker) I believe, he said go with 2.5 Cubic Ft per sub and a 70 inchs port in a 6 Cubic ft Box.

2x Incriminator Audio Lethal Injection 12 Inch Subwoofers.

I did some further refinements. This is what I came up with

Subwoofer Volume - 2.5 Cubic Ft

Port Hz - 32

Box Specs:

Width - 36"

Depth - 26"

Height - 14"

Net Volume - 6.36

Gross Volume - 5.08 Cubic Ft

Volume Per Woofer - 2.54 Cubic Ft

Volume Displacement:

0.22 Cubic ft - Woofers

.056 Cubic ft - Bracing 4x 45 Degree Corner Braces

1 Cubic ft - Port Volume

Port Specs:

Port Volume - 1 Cubic ft

Port Area - 91.05" Squared

Port Diameter - 10.77"

Port Width 2"

Port Height 12.5"

Port Length - 70"

Tuned - 31.75Hz

Nope not enough port area. Your calculations are off

Sorry Port area is 91.05" Squared

Also should I remove the brace closest to the port? How far is the opening of the port suppose to be from the wall/any object. Its only 10.25 inchs away from the 45 Degree Brace.
