port dimensions

[dropcivic]

Need to some help with port dimensions. I am running 2 dd 9515's off of two memphis mojo 4kw. The box is 20" deep, 17" high, and 56" long, good for about 9 cubic feet of airspace. I want to build the port tuned to 36 hz. Any help with the port dimensions?

If you build the port as the side of the box, and make it 15.5" tall by 7" wide, a 22" port leaves you with 36.17hz tuning and 7.64 cubic feet of airspace.

Doing the port at 15.5" tall and 6" wide, it only needs to be 17" long to give you a 36.12hz tuning, leaving you with 8.11 cubic feet of airspace.

This is with the whole box being single layered 3/4" by the way.
