Im helping a friend with a build for a DD 9515g
Box is 4 cubes and the slot port would be 30" x 2" for a total of 60 square inches of port"
My question is is the 2" of port sufficient in height or will air have trouble escaping the port? Do i need to do like 20x3" or 15" x4"?
It would be much easier to do the 30"x2"
