They use Polk's Dynamic Balance technology to deliver full-range sound. They are meant as an upgrade from an OEM speaker system.
The DB+ series is IP55 rated, so it resists dirt and water. It has also been tested for salt fog, UV and humidity. The polypropylene cone is UV tolerant and is built not to discolor or degrade over time. Waterproof inner and outer surrounds keep dirt, liquid and grime out of the speaker housing.
The speakers have a universal fit and drop in to cars, trucks, motorcycles, boats and ATVs. The tweeter is shallow and does not protrude, so a factory speaker grille can be reinstalled for a flush look.
