Tater, if you don't go with the SVS or Axiom, consider the Paradigm DSP series of subs, they offer decent bang per $$(about $500-$750 depending size). That Future Shop deal on the Velodyne also looks tempting ($499), I don't know a whole lot about Velo subs however, I take it they are more "box" store.

Half of communication is listening. You can't listen with your mouth.
