Dual 4Ω Voice Coils: This woofer features dual 4Ω voice coils, for wiring flexibility. When the voice coils are wired in parallel, the woofer presents a 2Ω load. When wired in series, the woofer presents an 8Ω load.
Marine Certification: Polk DB+ series speakers are marine certified (IP56 rated), 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 are not covered, we do not recommend using them in salt water environments.
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.
Sealed Box Volume: Polk recommends a sealed enclosure between 0.5 ft³ and 1.2 ft³.
Ported Box Volume: Polk recommends a ported enclosure between 0.66 ft³ and 1.2 ft³.
