Hmm, I was hoping to get at least one response. The plan for now is to build a box that will take up pretty much the entire floor under the shelf on the first level. It would be about 7 inches high, 20 inches deep and 40 inches across (pretty rough estimates, interior volume will be less). With those dimensions you get about 1.6 cubic feet per sub (2 tens). This should be plenty even after you account about 20% of the interior gone because of the unit itself (1.3 cubic feet then). Obviously the speakers will have to face up and I won't keep the shelf on top of the box when I'm using it.

Anyone have any advice, corrections, suggestions, etc?

Thanks,
Ryman
