Default how many ports. confused.

Ok, i built a 9.2 cuft box for my 4 12" jl w1v2's... i am wanting to use 4" ports, but i am lost on how to figure how many ports i need to get close to my "requires sq of port". I am looking to get the box ported to 35hz.

According to tthis site a 4" port has 12.566 sq. in. of area. That's a bit less than the recommended 16 sq. in. port per cubic foot but if you use aero's that'll make up for the lack in size. You'd need around one 4" aero per cu ft of displacement so 9 ports.

Running four 6" Aero's would make each Aeroport 23" long, thats a lot of space taken up inside the box for those ports. Why not just run four 4" Aero's, they'd only need to be 10.09" long. This is going off your 9.2 cu ft, not sure if this included your sub and bracing displacements or not.
