About the Polk Audio MM 1242 SVC

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 1242 SVC 12" 4-ohm subwoofer handles up to 420 watts RMS, with a titanium-coated polymer cone that'll stand the test of time. 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.

To drive this single subwoofer, we recommend a mono amplifier rated between 315 and 625 watts RMS at 4 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

Product Research

Features

Terminals: The woofer has heavy duty spring terminals that will accept single banana plugs, pin connectors, and bare wire up to 10 gauge.

Ultra-Marine Certified: Polk MM Series speakers are built to withstand exposure to moisture and UV rays, so they work well in boats and cars (IP56 rated).

Dynamic Balance: Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials create the least amount of resonance. Eliminating resonance in speakers results in a wide, smooth response and low distortion.

Sealed Box Volume: Polk recommends a sealed enclosure between 1.25 ft³ and 3.5 ft³.

Ported Box Volume: Polk recommends a ported enclosure between 1.75 ft³ and 2.25 ft³.
