Our GTX124H Series subwoofers are rated at 800 watts RMS / 1600 watts MAX power with a 2.5" voice coil configured for Dual 4 ohm impedance. All GTX 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.
