And I thought these were supposed to be good subs. Well, the CHEAP surround(foam) on the driver ripped out. I've had multimedia subs take more of a beating then that. And why did they use the foam junk. You would think they would be rubber. I was afraid of this when I first got it. Alls I have to say is i'm done with Hsu. The klipsch subs get shot down in here alot for some reason but from the ones i've heard i'm pretty amazed not to mention my vtf-2 doesn't put out near the bass as the klipsch subs do.
