I'm in a similar position as Raider. I have some nice mains which produce some good sounding bass, I've never been thouroughly convinced that a sub could do more than offer the earth shaking boom heard on occasion during a movie, and I'm not sure how good of quality bass would come from it when listening to some greatly produced music. NOT that I'm against seeing (er em hearing) to believe, but the jury is still out. HMMM I could be an ideal beta tester though
