Advanced materials and engineering

Polk Audio rethinks their legendary Mobile Monitor Series subs. Their MM1 Series subwoofers offer superior performance from lighter materials, so you'll get the impact you want without the extra weight of a conventional sub. They use advanced engineering and optimized components to reproduce your sound with uncompromising accuracy, and Polk built these marine-certified subs to take some serious abuse.

Efficient power handling

The MM 842 DVC 8" 4-ohm subwoofer handles up to 300 watts RMS, with a titanium-coated polymer cone that'll stand the test of time. This sub's dual 4-ohm voice coils allow you to wire your system to draw max power from your mono amp or to safely hook up multiple subs. The fiberglass-reinforced ABS basket resists flexing during heavy excursion, so your sub hits hard without distorting. The sub's inner workings are designed to handle the stress of heavy bass, so go ahead and turn it up.

Marine-certified

This sub has earned Advanced Ultra-Marine certification and an IP56 rating, which means it'll deliver powerful bass in some challenging conditions. The composite cone, waterproof surrounds, stainless steel mounting hardware, and ABS basket all resist corrosion, and the sub even features weep holes for proper drainage.
