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.
Rich, Deep Bass - Delivers thunderous sonic output and powerful low frequency response wherever you go.
Space-Saving Design - Slimmed down form factor reduces the need for oversized subwoofer enclosures for a look that goes virtually unnoticed—but a sound that doesn’t. Fits in any enclosure or application.
Dynamic Balance Technology - Enjoy a rich, clean, full-range sound with patented Dynamic Balance technology engineered into every DB speaker. Rigorously tested and developed by 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.
