Woofers
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 Certified Woofers: Polk db
Series speakers are built to withstand exposure to moisture and UV rays, so they
work well in boats and cars.
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.
Butyl Rubber
Surrounds: For a
smoother response and improved durability, the woofers use butyl rubber surrounds.
Kapton Voice Coil Formers:
The low-mass 2-Layer 1" Kapton Voice Coil formers are lightweight for high
sound output. Kapton's high melting temperature ensures high power handling
and excellent reliability.
Pole Plate Heat Sinks:
The pole plate heat sinks promote better heat dissipation for superior power
handling and reliability.
Tweeters
Silk/Polymer Composite
Tweeters: The 1" liquid-cooled,
silk/polymer composite tweeters provide clear, detailed highs.
Marine Certified Tweeters: Polk db
Series speakers are built to withstand exposure to moisture and UV rays, so they
work well in boats and cars.
Mounting:
The supplied mounting cups allow you to surface- or flush-mount the tweeters. The tweeters swivel in the flush-mount housings, allowing you to adjust them for optimum imaging.
