Using 3/4" material
With the outer dimensions I come up with
an internal volume of 3.71 cu ft.

Port displacement for a straight port that comes
out on the right side or left side of the box = .15 cu ft.

3.71 - .15 - .085 = 3.475cu ft.

3.47cu ft. with the port size 15.5 x 2.5 x 22.14
should be tuned between 32Hz-33Hz

BTW: I have an e15k in a 3.5cu ft. box [email protected]
and it sounds great! Great SQ and pretty loud too!
