Just call it the "Killer Kilo" subwoofer. This Massive Audio MMA124 Subwoofer delivers big bass for a car audio system that can't be ignored. The CEA 2031 certified 12" dual 4 Ohm subwoofer boasts a powerful 1000 peak watts and in the properly tuned box plays as low as 35Hz. The high-impedance aluminum former with 2" EISV voice coil lets you take full advantage of the amplifier, so you can drop the bass and hit the road in style. Built tough with high-quality materials, the MMA Series woofer is bonded to a heavy-gauge steel basket with industrial textured painting that helps protect and lower resonance. It's bolted to double-stacked, high flux Y30 Strontium ferrite magnets with an 8mm top plate to produce impressive, long-lasting sound. The laminated paper cone with pressed foam surround, springy poly cotton spider with woven round tinsel leads and round shape PP vacuum dust cap of this subwoofer help ensure it won't crackle and blow out over time. Crank up the volume and experience clear, clean sound with deep bass. With its high-quality construction, great sound and long-lasting performance, the MMA subwoofer series delivers high-performance audio for true car-audio enthusiasts.
