6 cubic feet net per sub. 16 sq in of port per cube and tuned to 36hz. Thats what I was told by DJ at Audioque. Use Exos box builder program that on the site here somewhere to design a box that will comply to those specs and fit in the area you have available.

height - 25"

width - 40"

depth (top) - 14"

depth (bottom) - 19"

port width - 4.5"

port width 2 - 7"

internal volume - 6.3-ish cubic ft (before woofer displacement)

tuning frequency - 36-ish Hz

port area - 105.75-ish square inches

16.75-ish sq inches of port per cubic foot.

CLOSE ENOUGH!

I'm not an enclosure guru, so my numbers could be off. I highly suggest someone give them a look.

[Vinnyhimself]

so shoot for a port with 96 in²

so shoot for a port with 96 in²

That number changes with relation to your net volume. You always have to find your net volume and then calculate what the sq area of the port is. A little bigger or smaller wont be noticeable.
