Dynamic Balance Technology
Enjoy a rich, clean, full-range sound with our patented Dynamic Balance technology engineered into every DB+ 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.
Marine Certified
The DB+ Series is IP56 rated so it’s dirt- and water-resistant. It also has been tested for salt-fog, UV and humidity. A big part of that marine certification also means that each speaker has a non-corrosive plastic grille, a polypropylene UV tolerant cone, waterproof inner and outer surrounds, and stainless steel mounting hardware, ensuring that it’s fully protected against the elements.
Polypropylene UV Tolerant Cone
Enjoy the peace of mind knowing each speaker cone is built to last, whose clean and polished look won’t discolor or degrade over time while giving heavy low frequency sound the high-performance it deserves.
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.
