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.
Woofer Cones: Each speaker features a Dynamic Balance polymer/mica
composite mineral-filled cone. The cones are stiff and lightweight for big sound and
Butyl Rubber Surrounds: For a smoother response and improved
durability, the woofers use butyl rubber surrounds.
Silk/Polymer Composite Tweeters: The speakers feature 3/4"
liquid-cooled silk/polymer composite tweeters for clearer, more accurate highs.
2-way Crossover Network: The built-in 2-way crossover network
sends the appropriate frequencies to each driver for cleaner sound and better
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.
