DB842 SVC

Audio enthusiasts love Polk’s DB+ Series Subwoofers for the rich, clean, and deep low frequency response they provide cars, boats, and ATVs. Built marine tough with a space saving design, DB+ Series Subwoofers add thunderous bass to your ride—wherever life takes you: the road, the trail, the waves—you name it.

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. Plus, our dual voice coil (DVC) subwoofers offer multiple impedance connections, allowing you to better match the performance of your amplifier for higher potential power. 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
