Polyglass Cone: The woofer cone has a cellulose pulp base
and is coated with a uniform deposit of hollow glass microballs. The addition of
the Polyglass layer significantly increases the cone's rigidity without adding
much weight. This combination takes advantage of the accuracy and neutrality of
the hard outer surface, but maintains the superior damping characteristics of
the cellulose pulp.
Surround: The butyl rubber surround is resistant to ultraviolet
rays, temperature extremes, and humidity to add to the speaker's reliability and
Voice Coil: The voice coil is wound around a 1" diameter
low-mass Kapton former, ensuring no coil deformation.
Inverted Dome Tweeter: The tweeter is an inverted
aluminum dome, producing a broad sound stage. The tweeter is angled and rotates
on its post, so it can be pointed toward the listener.
Size Classification Note: Crutchfield has traditionally referred
to this size speaker as a 6-3/4", while some manufacturers, including Focal, call
it a 6-1/2". Please refer to the Crutchfield Vehicle Selector to confirm fit in
