Of those, the I'm guessing the SVS PB10 will hit the hardest for movies. It will also be the largest. Second to that would be the Hsu. I think, in your budget and for your purposes, you might take a look at the Epik Legend. Also give the Emotiva Ultra Sub 12 a look, and the Elemental Designs A5s-300, A3-250, and A2-300. You might also consider the Outlaw Audio LFM-1 Plus, which has a nice sale right now, it's not a small subwoofer but it will have the most output, and comes with a free wireless adapter while on the current sale.
