Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
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.
5x7/6x8 Speaker: This speaker
can be used in both 5x7 and 6x8 applications. The supplied mounting adapter ring
allows the speaker to adapt to a 5x7 cutout when top mounted, and should be used
to achieve a good seal when bottom mounted in both 5x7 and 6x8 applications.
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
Kapton Voice Coil Former: The
low-mass, 2-layer 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.
2-way Crossover Network: The
built-in 2-way crossover network sends the appropriate frequencies to each
driver for cleaner sound and better imaging.
