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 MM1040UM 10" 4-ohm subwoofer handles up to 350 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 solidly without distorting.
Polk designed this sub specifically for marine use. It passes rigorous salt-fog and UV testing, and sports corrosion-resistant stainless steel input terminals. The sub is suitable for free air use, so you can mount it in a bulkhead or another suitable location without the need for an enclosure. Stainless steel mounting hardware is also included.
