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 :)

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