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
K2 Composite Sandwich Membrane/Cone: The FOCAL K2 Power 27KX
features a composite sandwich membrane/cone comprising of Kevlar, foam, and a
Kevlar material structure that is rigid, yet light weight, and allows fast bass
response without distortion. This cone structure features a thermoformed,
structural foam central core, coated with an Aramid fiber layer on the front
side and a glass layer on the back side. This hybrid technology significantly
improves membrane rigidity without raising the weight and allows long coil,
distortion free bass even at high levels. This composite sandwich membrane/cone
design offers an extremely rigid structure, improves power handling (300 watts
RMS/600 watts Peak), and has low distortion characteristics.
NBR Surround: The FOCAL K2 Power 27KX features a
long-throw NBR
(Nitrile Butyl Rubber) surround for long excursion, deep bass (35-1500Hz), and added
durability to promote long life.
Copper Voice Coil: The FOCAL K2 Power 27KX features an edge-wound
copper 1 layer/2.55" voice coil on a Kapton former (aluminum).
High-Performance Spider: The K2 Power 27KX features a high-performance
spider with integrated braids to form one complete layer. This spider
configuration eliminates wire fatigue, as well as wear-and-tear on the wire.
Multi-Ferrite Magnets: The K2 Power 27KX woofer
utilizes six dual-stacked Ferrite magnets (12 total) to create a powerful
magnetic field to help suppress compression and give better power handling. This
Multi-Ferrite motor assembly allows for greater efficiency (88db), higher power
handling capabilities, and natural cooling of the woofer's voice coil.
Die Cast (Zamak) Vented Basket: The FOCAL
K2 Power 27KX features a vented die-cast Zamak basket which is a rigid, non-magnetic,
and non-resonant frame that provides a strong, reliable structure for the
woofer. The vented basket provides a self-regulated coil cooling
system which allows air to flow freely preventing heat build-up and optimized
reliability and performance consistency.
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 K2 Power 27KX comes supplied with a
self-adhesive foam gasket mounting-ring for better chassis damping and to
prevent air leakage.
Removable Cloth Cover: The K2 Power 27KX woofer comes with a cloth
cover to protect the magnet from scratches or smudging during transport,
handling, and installation. The cloth cover should be removed once the woofer is
installed. The cloth cover is not designed to be placed on the woofer after it
has been installed.
Enclosure Compatibility
Recommended Sealed Box Volume: The FOCAL K2 Power 27KX is
designed to be installed in a sealed box with a volume between 0.71 cu/ft to
1.41 cu/ft. FOCAL recommends a sealed enclosure made out of 3/4" MDF with an
internal volume of 1.06 cu/ft.
