The Premium Upgrade—tuned to provide the unparalleled sonic accuracy you’ll find in studio monitor speakers, but in a durable, ultra-marine certified design, Polk’s MM1 Series mobilizes high-quality sound for an on-the-go audio upgrade that’s way beyond anything you’ll experience from the stock factory set up in your car, boat, motorcycle or ATV.
Every element of the MM1 Series is meticulously engineered for high-performance sound. Dynamic Balance technology, a proprietary 3-layer cone material, lightweight neodymium motor structure, high-temp Conex spiders and oversized voice coils for increased power handling are designed together with MM1 and offer truly a low pass crossover for optimum system blending — and what your vehicle might just become your favorite listening environment.
MM1 Series has earned an Ultra-Marine Certified IP56 rating with their non-corrosive aluminum grilles and fiberglass-reinforced ABS baskets, epoxy-coated crossovers, water-proof inner and outer surrounds, weep holes for proper drainage and humidity resistance. Salt-fog tested, UV and dirt, long-lasting protection against virtually anything mother nature can dish out.
All Polk loudspeakers rely on our patented process to eliminate electro-acoustic and mechanical issues before they become a part of the finished speaker and are also rigorously tested through Polk’s Klippel distortion analyzers. MM1 Series, in addition to the features mentioned earlier, offer IP56 waterproof rating and Ultra-Marine Certification. Features waterproof Santoprene surrounds that keep the elements out and protect the speaker housing, maximize throw, and withstand abuse from marine cleaning agents.
Provide lighter, clearer, more accurate sonic dispersion—and won’t discolor or degrade with time and heavy use.
