Any experience with the Sound Ordnance B-8PT?

I'm looking to add a bit of bass to my new system. I just put components in the front doors, now I'd like to add a bit more. I don't need something that shakes the neighbors. I listen to mostly rock music. Sound Ordnance™ B-8PT 120-watt compact powered subwoofer at Crutchfield.com

Reviews seem promising. Crutchfield is overpriced imo tho

$150 for a powered 8" sub doesn't seem out of line to me.

Hoping for some more experiences or recommendations.
