Everything you love about Polk’s Dynamic Balance technology—that rich, clean, full-range sound—is built into the marine-tough, yet ruggedly sophisticated, DB+ series. And with its universal fit, it can be installed in any vehicle: Automobiles, motorcycles, boats, ATVs—you name it. 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. 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.
