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 low distortion.
a smoother response and improved durability, the woofers use butyl rubber

low-mass two-layer 25mm Kapton Voice Coil former is lightweight for high sound output. Kapton's
high melting temperature (725°F)
ensures high power handling and longer reliability.
Silk/Polymer Composite Tweeters:
The 3/4" liquid-cooled, silk/polymer composite tweeters provide clear,
detailed highs. The tweeters use neodymium magnets.
Pivoting Tweeter: The tweeter
pivots, allowing you to aim it toward your listening position for better
2-way Crossover Network: The
built-in 2-way crossover network sends the appropriate frequencies to each
driver for cleaner sound and better imaging.

utilizes a flat spider for faster, longer excursion linear motion.
Pole Plate Heat Sink: The
speaker's pole plate heat sink promotes better heat dissipation for superior
power handling and reliability.
Woven Leads: The speaker
features flexible woven leads sewn directly into the spider for greater
Basket: The speaker is housed
in a solid, acoustically inert stamped steel basket finished in rustproof gun
Grilles: Strong ABS plastic
grilles are included. These computer optimized grilles are based on exclusive
