SVS is currently running a closeout special on their PB12-NSD. It's $499 shipped, 5 year warranty and 45 day in home trial period. It goes down to 18Hz +/-3db. 400W continuous, 800W peak. It's gotten stellar reviews over they years. I ordered one for my bar area to complement the M5HPs. I'll be receiving it this week and will try it out on Friday.
