Guy at work was bragging about this sub today. Read about it in S&V at the health club. Told me if I looked into it I would have "buyer's remorse" because of the dual Tempest sonosub I'm building. Here's the specs from the ad: 1200 watt powered subwoofer 22 Hz to 100 Hz at 107db 9x9x9 107db @ 22hz or 100hz??? Can this little thing really do 107db @ 20hz or is it media hype?? I'm still pretty sure my dual Tempest beast will kick it's butt when finished.
