Polk Audio DB522 DB+ Series 5.25 Coaxial Speakers with Marine Certification

Dynamic Balance: Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials create the least amount of resonance. Eliminating resonance in speakers results in a wide, smooth response and low distortion.

Marine Certification: Polk speakers are marine certified, making them a good choice for boats in fresh water, convertibles, motorcycles, ATVs, and other applications where the speaker might get wet. Because they have coated steel baskets and the terminals and crossover components are not covered, we do not recommend using them in salt water environments.
