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 Woofer: Polk db
Series speakers are built to withstand exposure to moisture and UV rays, so they
work well in boats and cars. They also include stainless mounting hardware for
corrosion and rust resistance.
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.

Crossovers
2-Way Crossovers:
Each Butterworth outboard crossover features a 12dB/octave, 4000Hz high-pass network for the tweeter
and a 12dB/octave, 4000Hz 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.
Crossover Connections:
The crossover inputs and outputs are screw terminals. The crossover housing is
vented, giving you a choice of hidden wire channels for easier, more
professional-looking installs.
Mounting:
There are two mounting holes in the base of each crossover.

L=5.029", W=3.072", H=1.075"
