Just remember that you are buying an 8" subwoofer and you shoud not expect the performance level of a 10" or 12" sub from such a small beast, and you'll love the sound this thing creates. Doesn't go quite as low as I'd like it to, but is amazing for its size.

The build quality on this sub is exceptional. It handles 375w rms no problem. That being said it lacks on lower frequencies even compared to other 8" subs. I installed this in a .3cf sealed box. Sounds decent, but would be much better ported. All-in-all a well built woofer for the money.
