Features
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 longevity.
Inverted Dome Tweeter: The tweeter is an inverted Aluminum/Magnesium dome, producing a broad sound stage. A switch on the tweeter allows adjustment of the tweeter output; choose flat or +3 dB.
4/2 Hole Compatibility: Most 4″ factory speakers use four mounting screws, however, in some vehicles, only two are used. The ICU 100’s mounting tabs can be removed, allowing installation in 4-hole or 2-hole applications. Care should be taken handling the speaker after any tabs are removed because the broken edges may be sharp. Please enter your vehicle information to confirm fit.
