Box Specs for Havoc or Q15

[mattd0344 2]

I'm thinking about either getting an AA Havoc 15" or a Fi Q 15" with all the options. The box that I'm planning on getting is a 4 cubic foot vented box with a port tune of 32 hertz. Would this be a good box for either of the two subs??? Heres the site of the box too.
