Massive Audio 2x 12" 3000 Watt Subwoofers 2.5" Dual 4 Ohm Voice Coil MGK124 W/ Massive Audio Monoblock 1 Channel Full Range Amplifier 1500 Watt Class D E3F

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 thats sewn through a UV treated non-pressed paper cone onto a Pressed Foam surround. Then its bonded to a heavy gauge steel basket thats 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.
