Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.

Features
Polyglass Cone: The FOCAL Polyglass
27V1 features an 11" polyglass cone woofer for a wide, dynamic frequency response
of 35-500Hz that offers great bass and mid-bass 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.
Aluminum Dust-Cap: The Polyglass 27V1 features an aluminum dust-cap
with an engraved FOCAL logo for a more esthetic look.
NBR Surround: The FOCAL Polyglass 27V1 features a NBR
(Nitrile Butyl Rubber) surround for long excursion, deep bass, and added
durability to promote long life.
Aluminum Voice-Coil Former: The Polyglass 27V1 woofer features
a 4
layer, 2.0"
diameter, 4-ohm, aluminum voice-coil former for higher power handling capabilities up to
250 watt (RMS) and 500
watt (Peak).
Louvered Cooling System: The Polyglass 27V1's
Louvered Cooling System is self-regulated ventilation system which increases air
cooling, prevents heat build-up, and provides optimized reliability with
performance consistency.
Ferrite Magnet: The Polyglass 27V1 woofer features a120mm (4.75"),
25mm (1") thick
ferrite magnet
for higher sensitivity up to 90dB (2.83V/1m).
Die Cast Chassis: The FOCAL
Polyglass 27V1 features a die-cast Zamak chassis which is a rigid, non-magnetic,
and non-resonant frame that provides a strong, reliable structure for the
woofer.
Spring-Posts: The FOCAL 11" woofer is equipped with a pair of
nickel-plated spring-post speaker terminals for easy connection up to 10AWG wire.
Foam Gasket: The Polyglass 27V1 comes supplied with a
self-adhesive foam gasket mounting-ring for better chassis damping and to
prevent air leakage.
Rubber Magnet Boot: The Polyglass 27V1 features a
rubber magnet boot to protect the woofer's magnet from shocks and corrosion. The
rubber boot is removable.
Enclosure Compatibility
Recommended Ported Box Volume: The FOCAL Polyglass 27V1 is
