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 they are fully protected against the elements.

Designed To Go The Extra Mile

DB+ Series, in addition to their IP56 waterproof rating and Marine Certification feature waterproof surrounds that completely block dirt, liquid, and grime from entering the speaker housing—all designed to maximize longevity of the speaker.
