Massive Audio 12" 1500 Watt Subwoofer 2.5" Dual 4 Ohm Voice Coil MGK124

Our MGK Series subwoofers are rated at 750 Watts RMS / 1500 Watts MAX power with a 2.5" voice coil configured for dual 4 ohm impedance. All MGK subs use tight Red stitching that?s sewn through a UV treated non-pressed paper cone onto a Pressed Foam surround. Then it?s bonded to a heavy gauge steel basket that?s bolted to double stacked High Flux Y30 120oz Strontium ferrite magnets with a 10mm top plate. Then everything dances on a springy poly cotton spider with high powered woven tinsel leads that connect to spring loaded 5-way binding nickel plated speaker connectors. These woofers scream sound quality and truly represent Massive Audio's commitment to value and performance.
