About the Focal Polyglass 170 V
Focal's Polyglass V component systems use precision craftmanship and advanced materials to make a strong sonic impression. Each system includes two tweeters, two woofers, two crossover networks, grilles, and assorted hardware.
2-layer woofer cone and ABS basket
The 170 V system features a 6-3/4" woofer with 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. The basket is made from a fiberglass/ABS mixture, providing a non-magnetic, non-resonant housing that won't color the sound. A butyl rubber surround helps control cone movement and promotes high power handling.
Aluminum/magnesium tweeter
Focal designed the aluminum/magnesium inverted dome tweeter to disperse high frequencies evenly for a big, open soundstage. The external 2-way crossover ensures a smooth transition from lows to highs, so vocals and instruments sound natural. Grilles are included.

Product Research
Woofer
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 rubber surround is resistant to ultraviolet rays, temperature extremes, and humidity to add to the speaker's reliability and longevity.
Phase Plug: The bullet-shaped aluminum phase plug in the center of the woofer ensures a smooth, flat off-axis frequency response by preventing the high frequency sound waves emanating from one side of the cone from interfering with sound waves from the other side of the cone.
Aluminum Basket: The woofer features a non-magnetic cast aluminum basket.
Tweeter
Inverted Dome Tweeter: The tweeter is an inverted aluminum dome, producing a broad sound stage. The tweeter has a Neodymium magnet to provide a powerful magnetic field for the voice coil, while still maintaining the tweeter's compact dimensions.
Mounting Options: The tweeter can be surface or flush mounted using the included adapters. Focal recommends flush mounting, but the included angled cup allows surface mounting at one of two angles; approximately 20° and approximately 40°.
Crossover: The included high-pass crossover is attached to the tweeter only; the woofer uses its natural mechanical roll off. The crossover slope is 12 dB/octave and the crossover point is 4,300 Hz.

These are great speakers, I bought and fitted a second pair int he back of my c300' (they fit crutchfield), they sound harsh at first, but warm up as eye broke in. Also, Hespe seem to do best with the crossover to a sub at around 80-90hz.
