ported calculations for ed15k?

[Mercureie]

this will be my first ported box build and i jus wanna make sure all my numbers line up before i start cuttin. im shootin for a net vol. of 3.5 cuft tuned to 33 hz. the outer dimensions are
W:30 in
H:17 in
D:16 in
driver displacement: .085 cu ft
Slot Port-
H:15.5
W: 2.5
L: 22.14
displacement : .496 cuft

could someone check me on this jus wanna make sure this will all work out. thnx for all the help.

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 tuned@33Hz
and it sounds great! Great SQ and pretty loud too!
