It's gonna be 2 Fi BL 12's fully loaded. The box is gonna be built by a local shop and I requested a pretty big port to move some air so they asked me for the size of port i wanted. Its gonna be 5 ft3 and tuned to 33 hz.

i would use about 80 inches of port area

calculator says 65 but from personal experience with the BL they perform better with a little more

so if i made the port 16x5 how deep would it need to be or is there other dimensions you would use?

heres a calculator for that Port calc

if your net internal volume is 5 cubes and 16x5 port then it needs to be 32 inches long

Just be sure that you end up with your desired net volume after taking all displacements into consideration.
