Yeah, Get the Energy - I doubt you'll be disappointed. Looks like your local Craigslist has some scores on it - Nice! I just picked up a Def Tech Pro Sub 1000 this morning for $95 (10" woofer, 10" passive radiator, 300 watts RMS). Best Buy still sells this sub for $499. The guy was nice enough to hold it for me for a day and a half until I could make it over to pick it up.
