Just a comment on Bacardi's comment re: SVS subs w/EQ-1 being superior to JL. I'm sure that he's right. I also suspect that any half-decent sub mated to an EQ-1 (or Velodyne SMS-1) PEq unit will outperform a superior sub with no PEq - particularly for music. (As to HT performance, the JL and SVS subs both appear to be stellar performers. Again my opinion on the SVS must be qualified by my comments re: no first hand experience in my previous post.)The SMS or EQ-1 can be used with any sub, including the JL. Note that the EQ-1 requires a x-over unit ahead of it in the chain, as it was presumably designed for use with HT receivers or pre-pros. The SMS-1 includes a built in crossover but -IMHO- it kinda sucks, so you'd probably want a separate x-over for high pass anyway. I use an NHT x-2 for this purpose.
Good Luck.
