Polyglass Cone: The FOCAL Polyglass
27V2 features an 11" polyglass cone woofer for a wide, dynamic frequency response
of 35-500Hz that offers neutral, coloration free sound. The uniform deposit of
hollow-glass microballs over the entire cellulose pulp cone greatly increases
its rigidity without adding significant weight, so you get a woofer that is
durable, yet efficient, and sounds great.
NBR Surround: The FOCAL Polyglass 27V2 features a NBR
(Nitrile Butyl Rubber) surround for long excursion, deep bass, and added
durability to promote long life.

Dual 4-ohm Voice Coils: This woofer features dual 4-ohm
voice coils that offer flexibility in wiring. When the voice coils are wired in
parallel with each other, the woofer presents a 2-ohm mono load. When the voice
coils are wired in series with each other, the woofer presents an 8-ohm mono
load. In addition, each coil may be connected to a different amplifier channel
and each channel will see a 4-ohm load.
Louvered Cooling System: The Polyglass 27V2's
Louvered Cooling System is self-regulated ventilation system which increases air
cooling, prevents heat build-up, and provides optimized reliability with
