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
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
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
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
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.
