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 extremely clear highs, mids and lows no matter what you’re listening to.
MM1 Series has earned an Ultra-Marine Certified IP56 rating with non-corrosive fiberglass reinforced ABS baskets, epoxy coated crossovers, waterproof inner and outer surrounds, weep holes for proper drainage, and titanium-plated cones—that’s all been salt fog, UV, and humidity tested. With MM1 Series, you get extra, long-lasting protection against virtually anything mother nature can dish out.
Our newly designed Terylene dome tweeter features curvilinear formers that extend response and lower resonance for better dispersion in the critical midrange, delivering clear and detailed high-frequency response for realistic reproduction of vocals and instruments.
The ultra-flexible high-performance material maximizes throw with its ultra-durable, dirt- & water-resistant design, and prevents the resonant distortions of less-damped rubber surrounds. Plus, it resists the harsh effects of direct cleaning agents.
Every element of the MM1 Series is meticulously engineered for high-performance sound—Dynamic Balance technology, lightweight neodymium motor structures, glass fiber formers, oversized voice coils and high-temp Conex spiders for increased power handling.
