here's the frequency response, and cone displacement graphs... you'll well within the X-max, so distortion should be low. QTC of a 1cuft box per sub is .691, fairly low for a sealed setup.

Red line = 2cuft sealed (1cuft each) looks like usuable range down to 30hz.
Blue line = 10cuft sealed (to simulate what an IB setup might look like)
The IB can safely play about 5hz lower than the Sealed can, I don't know what the x-mech is on that sub, so its possible it could safely play much lower, but with added distortion.

That is my subwoofer an IDQ 12v3 D4 in a sealed box of 1 cu feet. and I can only say good things.
