I bought this sub expecting great things, and overall I was disappointed. The sub does pack a lot of bass, but generally it's boomy, loose bass without real punch or control. The louder you turn it up the louder the boomy, hummy bass becomes, but it never transcends to the kick/thump you want. Also, and this is my biggest gripe with the unit, after a few months of use the amp started to die and now the sub makes a cracking noise any time it's in standby and sometimes even when it's on. It pops, snaps, and generally annoys me so much that I've replaced it with a Klipsch SUB-12 that goes MUCH lower and sounds much more controlled. It also has a lot more power for solid kicks. I think CerwinVega is just a name now, the quality is gone since the company was sold to the Stanton Group, a Chinese consortium that makes the subs at bottom dollar, slaps the CW name on them. Buyer beware.
