Focal Polyglass 100 CVX
4" 2-way speakers
Our take on the Focal Polyglass 100 CVX by Crutchfield's Buck Pomerantz
Focal's Polyglass CVX speakers use precision craftmanship and advanced materials to make a strong sonic impression. These sturdy 2-way speakers bring superb sound quality to the factory speaker locations in your vehicle.
2-layer woofer cone
The 100 CVX 4" speakers feature a Polyglass cone that's created by depositing a layer of hollow glass microbeads over a layer of cellulose pulp. This unique material combines the warm sound of cellulose with the incredible strength of glass, for a cone that responds rapidly with extremely low resonance. A butyl rubber surround helps control cone movement and promotes high power handling. The ABS plastic basket provides a strong, non-resonant housing for accurate, uncolored sound.
Unique tweeter design
Focal designed the aluminum inverted dome tweeter to disperse high frequencies evenly for a big, open soundstage. You can rotate the tweeter to improve definition in your listening area. The built-in 2-way crossover ensures a smooth transition from lows to highs, so vocals and instruments sound natural. Grilles are included.
Priced per pair
Very nice midrange. High quality construction and design, even if made in China. Great punch even though it is only a 4"speaker.

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.
Basket: The woofer features a basket made of 20% fiberglass filled ABS.
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 rotates on its post, so it can be pointed toward the listener.
Crossover: The 12 dB/octave crossovers built onto the back of the speaker use audiophile grade polypropylene capacitors and air core inductors to ensure high definition and a dynamic sound quality.
