So I'm "shrinking" the hole down to accommodate a 10" subwoofer. Still .82 cubes. So here's what I'm left with: SSA DCON 10D4 - wants .75 to .9 cubic feet Image Dynamics ID10 - wants .6 to .8 cubic feet RE SR 12 - wants .5 to .75 cubic feet, but it's a 12" subwoofer, which is a plus. AA Assassin 10 - wants .6 - 1.0 cubic feet Help me choose one. They're all between $100 and $160 and they do between 250 and 350 watts RMS.
