I would like to buy a sealed sub for ~ $400. Im looking for something more music oriented than HT. One consideration is the JBL 8400. I have read only a little about it as it doesnt seem very popular like the Id brands. And yes, I understand the ID thing and would probably buy the Epic Valor if I could afford it. Or, if I had the space I'd go with the csx-15 and forget the music focus and go for the rumble, wow, fun factor! Anyway, if you know of a better or alternative sealed sub in that price range I would appreciate the suggestions. Also, if you have owned or listened to the JBL 8400 please share your experience.
