Effortless Bass On The Go
Audio enthusiasts love Polk’s DB+ Series Subwoofers for the rich, clean, and deep low-frequency response they provide to 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.

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

Marine Certified
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, providing protection against the elements.
