As the other reviews say, loud sub that makes decent bass for the money. Low end signs off (makes weird noise) so a subsonic filter would be handy with these subs. Bass drum kick hits hard for two twelves though. Quality leaves a bit to be desired as the terminal post on one was not attached right out of the box. Surround let go of the basket on one sub as well after about 10 hours. Nothing a zip tie and some cyanoacrylate glue didn't take care of. As said, for the price I guess you can't go wrong considering I've had similiar issues with high end subs before.
