Future box, Check this info please.

Hey, I was just looking at some subs and playing with the numbers to see what kinda box I should build. The subs are:

Hifonics Goliath XX3215

3200W RMS

Fs 31.5hz

Vas 57.8

QTS .38

Xmax 25mm

Now they say 3cu. ft per sub and a (1 X 15) X 6 port

The port made no sense to me so I ran it through a port calculator and this is what I got.

For 2 subs: (minimum 171sq. " port area.)

6 cu. Ft

Port = (9 X 20) X 58.75

Tuning = 33hz

What do you guys think, (without suggesting other subs please,) for a box with these?
