Clamp-Ring Mounting
Our rectangular in-wall models utilize a
clamp-ring mounting system which
maximizes clamping surface. By distributing
the clamping force over a larger surface area,
the pressure on your sheet rock is reduced
while the overall mounting strength is
increased. The mounting ring comes
pre-assembled to the loudspeaker frame
dramatically reducing installation time.
Kevlar® Woofers
The strength of Kevlar® helps the cone retain
its shape at very high energy levels and its low
mass assures quick, accurate response. The
cone's woven surface delivers smooth,
uncolored mids. The kapton voice coil former
and butyl rubber surround ensure that these
woofers will provide years of consistent,
reliable performance.
Phase Plug Technology
In any conventional loudspeaker, the highest
frequencies of audio emanate from the area
around the center of the cone and the lower
frequencies are produced by the area of the
cone that is farther from the center. In fact, the
distance from the center at which a sound
wave will come off a loudspeaker cone is
directly related to its frequency. This helps
explain why larger cone loudspeakers are
usually capable of producing more bass.
Due to the shape of the conventional
loudspeaker cone, the higher frequency sound
waves tend to collide at a focal point. This
causes phase distortion and a loss in clarity. As
a result, accuracy and transparency suffer. This
also has detrimental effects on the realism of
the sound environments created by today's
high fidelity digital audio and surround sound
systems.
The phase plug pole piece extension improves
driver performance and clarity by deflecting
delicate midrange audio out into the sound
space and minimizing distortion producing
collisions.
Tetoron® Soft Dome Pivoting Tweeters
Tetoron® soft dome tweeters deliver natural,
uncolored high frequency audio evenly over a
wide dispersion pattern. Ferro Fluid is used in
the voice coil gap to lubricate and cool it. This
significantly increases power handling and
improves transient response. The pivoting
feature allows the already wide dispersion
pattern to be aimed directly at the central
seating/listening area delivering a seamless,
transparent and coherent sound space.
Baffle Mounted MF & HF EQ switches
Numerous factors affect loudspeaker sonic
performance, such as placement and
proximity to corners. Midrange and high
frequency equalizer controls placed
conveniently on the front of the loudspeaker
baffle allow the user to adjust the high and
middle frequency response of each
loudspeaker to compensate for differences in
environment and placement.
Fine Mesh Grilles & Elegant Frames
The frames & grilles are factory finished in
satin white, which will stand as a finish on its
own or serve nicely as a primer base if painted
to match or complement wall finish or room
décor without the need for any additional
preparation.
Spun cellulose grille inserts provide sonic
transparency yet visual opacity so the
individual driver components are not visible
through the grille.
Every Preference model loudspeaker is "timbre-matched" ensuring sonic
uniformity throughout the line. This means all models have been carefully
engineered to have a family sound; this is also referred to as "voice matching".
As special effects from movie soundtracks move about the room,
timbre-matching ensures a consistent tonal balance throughout the sound
space. This creates that convincingly realistic three-dimensional spatial image,
which completely absorbs the viewers into the cinematic experience.
A home theater system may now consist of various loudspeaker sizes and
shapes as dictated by room décor and layout, all the while delivering a
seamless, transparent and coherent sound space.

IR Receiver Knockouts
The K-602, K-802 and K-5LCR rectangular
in-wall loudspeakers feature a mounting
provision for a remote control signal receiver
behind the loudspeaker grille. This allows
discrete integration with an infrared
receiver/repeater system. These systems work
with your standard IR remote controls to
allow command of your entire system from
any equipped room in your house.
