Overview

The Polk DB5252 5.25" Component Speaker System with Marine Certification delivers legendary sound quality that transforms your vehicle's audio experience. Engineered and designed in Baltimore, Maryland, these speakers feature an IP56 waterproof rating and are tested for salt-fog, UV and humidity. The DB+ Series are Marine Certified to push the limits of durability, so you can take them anywhere.

Superior Sound Engineering

Polk's exclusive lightweight Dynamic Balance® Polypropylene Cones deliver spectacular midrange clarity, punchy bass and high efficiency. The system includes separate 5.25" woofers and 0.75" silk dome tweeters with external crossovers that direct frequencies to the proper drivers for seamless performance. Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials create the least amount of resonance.

Universal Installation Compatibility

Built marine tough and designed for a universal fit, DB+ series power the soundtrack of your ride wherever life takes you, on the road, the trail, the waves—you name it. The zero-tweeter protrusion design ensures that your factory grilles reinstall seamlessly, while the included mounting options accommodate both flush and surface tweeter installations.

Marine-Grade Durability

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 they are fully protected against the elements. Waterproof surrounds completely block dirt, liquid, and grime from entering the speaker housing—all designed to maximize longevity of the speaker.
