   Big From Lebanon
Hooked it up to an Alpine F1 CDA-7990 with the big MRV-F1507 amplifier with +4dB at 40Hz and Q=1 in a 1.5 ft3 sealed enclosure. Although I have some of the best equipment on the market running it, I wasn't very impressed with sound quality. However, it has good response time and pretty loud and clean sound reproduction; top that with an excellent price-quality ratio => A great buy!

I'm running one of these in a sealed 1.3 ft3 box (with RF 550S amp) in a mid size sedan and I have no problem hitting 140dB at the dash (Epic 150). And that's with the sunroof open. Appears to be built to last. It does take a while to break in (I have 50+ hours on it and its still going). It also has the clarity and tightness of a 10 inch. Overall I am very happy with this sub.
