As above lol
Messing here with BBP but not sure about the things here
So box is 16.1 cubic feet when subs in box ...
Box height is internal 31.89 inch so that should be a port height as well ....
I know about the suggested port area, 10-20 sq inch per 1 cft
BBP suggest me 6.31 inch wide port so it should be tuned on 70hz ... is that correct ?
Just a bit confused here as ive seen lots wider ports ...
tnx for your attention

Cganged my mind, wanna tune it to 68 hz
Thats for the SPL
I can always go lower with that port, i mean its LOTS easier ... so thats the start point
