Ma Audio HardKore 15" competition subwoofer

Impedance = 1.5 ohms Powered at 900 watts RMS 4 cubic foot sealed enclosure I have maxed out a 136.5 dB sound meter so I know it goes at least that loud. My camera only runs at 15 frames/sec so it doesn't really capture what the sub is doing very well. [ go to Youtube.com ]
