Polk Audio MM1240D

Polk Audio's Mobile Monitor Series subwoofers bring out superior performance from lighter materials, so you'll get the impact you want without the extra weight of a conventional system. Advanced engineering and optimized components reproduce your sound with uncompromising accuracy, for low end that is rich and clear. The MM1240D 12" dual voice coil subwoofer handles up to 425 watts RMS. A copper voice coil and neodymium magnet motor drives the polymer cone with exceptional efficiency. The carbon composite basket features a "wagon wheel" design that resists flexing during heavy excursion, so your sub hits sub hits solidly without distorting. The dual 4-ohm voice coils offer options for wiring a multi-sub system or drawing maximum power from your mono amplifier. This sub is certified for marine use, and Polk includes corrosion-resistant stainless steel mounting hardware.
