Go listen to a JL W7, RE XXX, Fi Q, IDQ, or something along those lines and then tell me how loud or great they sounded. I'm not a brand *****, and I even know better to never even try to play off Volfenhags, Audiobahn, Dual or (insert craptastic cheap walmart brand sub here) as being loud as hell or having good sound quality. I will have to say though that if you haven't heard anything good like the ones listed before, then you really don't have anything to compare to. Shit, the people in my area think my 15" Rockford T1 is one of the loudest systems around. Only if they knew.... lol
