Premium Upgrade Tuned for the total sonic accuracy you get in a studio subwoofer, the MM1 Series reconfigures this kind of high-quality deep bass impact for an on-the-go listening experience that totally outperforms your OEM factory setup.

Advanced High Performance Bass Every element of the MM1 Series is meticulously engineered for thunderous bass, enhanced sonic detail and ultra-durable construction-Dynamic Balance technology, a high excursion bump stack motor structure, glass fiber formers, multilayered and oversized voice coils, high-temp Conex spiders, a vented pole and basket structure, and integrated fuses.

Dynamic Balance Technology Enjoy a rich, clean, full-range sound with our patented Dynamic Balance technology engineered into every MM1 speaker. Rigorously tested and developed by our talented Polk Audio engineers, whose passion rests in the principles of great sound, Dynamic Balance technology features non-resonant materials so you get clean, core-pounding lows no matter what you're listening to.

High Excursion Bump Stack Motor Enjoy more audible throw for a deep bass experience that's bound to excite your senses.

Multilayered Voice Coil Provides increased motor strength for tighter, more accurate sound.

Glass Fiber Formers, Oversized Voice Coils and High Temperature Conex Spiders All three combine to create a high efficiency driver, for clean, clear bass, increased power handling, better linearity, lower distortion and greater durability.

Vented Pole and Basket Structure Offers increased cooling, power handling-and minimized air chuffing.

Integrated Fuses Protects the subwoofer against overpowered amplifiers.

Ultra-Marine Certified Featuring an IP56 rating that's dirt- and water-resistant it includes a non-corrosive fiberglass reinforced ABS basket, a water-proof surround, weep holes for proper drainage and a composite cone for extra, long-lasting protection against the elements-all of it salt-fog and UV tested.

Waterproof Santoprene Surround This attractive high performance material maximizes throw with its ultra-flexible, ultra-durable properties-and prevents the elements from entering the speaker unit. Plus, it combats the harsh effects of boat cleaning agents.

Non-corrosive Fiberglass Reinforced Baskets Offers heavy-duty protection for back half of the speaker, which helps prevent corrosion and general wear and tear.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
