Ported box opinions

[Diablo6699]

I want a ported box for my 2 mach 5 audio 15's, i like sq, but i am more than willing to give some up if it will be louder with less sq. I was thinking somewhere around 5 cuft at 38 hz. I really need some opinions though

if you have room do 6 cu. ft.
I wouldnt tune any higher than 35. I think theyll be plently loud even tuned to 32.
