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.

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.

With its second order high/low pass system, you’re ensured the right frequencies reach the right speakers in your setup for optimal system blending regardless of the vehicle you’re in or the elements you encounter.
