Our DB+ Series Subwoofers utilize our patented Dynamic Balance Technology to combine Polypropylene woofers, non-resonant materials, and exceptional power handling for crystal clear sound with deep, effortless bass. Their slimmed down form factor reduces the need for oversized subwoofer enclosures. You get a look that goes virtually unnoticed—but a sound that doesn’t.
DB+ Series Subwoofers are IP56 rated so they are dirt- and water-resistant. They also have been tested for salt-fog, UV and humidity. A big part of that marine certification also means that each subwoofer has a UV tolerant cone, waterproof surrounds, and stainless steel mounting hardware, ensuring that they are fully protected against the elements
All Polk loudspeakers rely on our patented process to eliminate electro-acoustic and mechanical issues before they become a part of the finished speaker and are also rigorously tested through Polk’s Klippel distortion analyzers. DB+ Series Subwoofers, in addition to offering IP56 waterproof rating and Marine Certification, have waterproof surrounds that completely block dirt, liquid and grime from entering the speaker housing, all designed to maximize longevity of the speaker.
50 years, hundreds of thousands of speakers, and countless awards later, we are still focused on our mission of giving you the absolute best sound for your money. Great Sound for All.
