As above lol

Messing here with BBP but not sure about the things here :crying:

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 :)
