Have a few ??'s on BTL box design

[Casper97TA 0]

The box I'm building is for a single Fully loaded BTL 15. The design i came up with has the following specs: 4.5 cubes after displacement and bracing, tuned at 32hz with 64sq/in of port. My goal is just a loud ass daily ground pounder. My question is just does this box seem too big/small, and is 64sq/in too much port? thanks

sounds like your right with in the specs of 12-16sq inches per cube so you should be good on port area

same with box size, looks alright to me
