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.
Each speaker features a Dynamic Balance polymer/mica composite mineral-filled
cone. The cones are stiff and lightweight for big sound and low distortion.
Surrounds: For a
smoother response and improved durability, the woofers use butyl rubber
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
Pole Plate Heat Sinks:
The pole plate heat sinks promote better heat dissipation for superior power
handling and reliability.
Mounting Ring: The supplied
mounting ring has mounting holes for both 6-1/2" and 6-3/4" applications, including GM/Chrysler 6-3/4G,
allowing the speaker to fit more vehicles. In most cases, the ring should be
used to mount the speaker.
Tweeters: The 1" liquid-cooled,
silk/polymer composite tweeters provide clear, detailed highs.
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.
Each Butterworth outboard crossover features a 12dB/octave high-pass network for the tweeter
and a 12dB/octave low-pass network for the woofer.
Tweeter Attenuation Switch: You
can adjust the output of the tweeter to match a level appropriate to your
vehicle or your system. On the end of crossover (opposite the terminals), the
tweeter attenuation switch can be set to 0dB, -3dB, or +3dB.
Electronic Tweeter Protection
Circuits: Each crossover has a
built-in protection circuit that guards the tweeter against accidental damage
from high power.
The crossover inputs and outputs are screw terminals. The crossover housing is
vented, giving you a choice of hidden wire channels for easier, more
There are two mounting holes in the base of each crossover.
