What do you mean by "2 3 or 4 6"?

If you mean 3" across, the ports would only be 2" long if you had two of them.

If you mean 2 ports that are 6x3 or 4 ports that are 6x6, neither of those are long enough. Four 6" ports would have to be 27" long each, two of them would be about 11.5" long each.

what i meant by 2 3 or 4 is how many would be necessary for 2 15s, i can do all calculations beyond that myself just dont know how many in^2 per ft^3 necessary when using aeros et cetera.

Oh! So you meant do you need 2, 3, or 4 six inch ports?

For seven cubic feet, two should be plenty. Doing the math I figure ONE sixer is good for a 4.5cu box, two should work just fine for seven.
