Introduction
The AT or Advanced Technology group of
In-Wall Loudspeakers are designed to
deliver truly stunning performance with
optimum installation flexibility. All models
in the AT series are constructed using the
highest quality components and utilize
advanced materials technology to create
speakers capable of reproducing both
music and movie soundtracks with stun-
ning realism and sonic impact. They are
perfect anywhere that quality of sound is
the most important consideration.
An AT8000 Series Speaker Kit;
AT8000 Series Bracket Kit; and an
AT8000 Series Frame/Grille Kit are
required to install one AT8000 Series
In-Wall Loudspeaker in either new
or existing construction.
Features and Benefits
High Performance Woofer and
Tweeter Designs
Both the AT8000 and AT8200 incorporate
woofer designs which feature inverted
dust caps, butyl rubber surrounds, and
Niles exclusive BumpBack™ magnet
structure to provide powerful and accu-
rate bass response. Additionally, both
models feature tweeters housed in a zero-
diffraction swiveling enclosure which can
be positioned up to 15 degrees off axis to
deliver optimum clarity regardless of
speaker placement or listening position.
AT8000
Interlaced Carbon/Glass Fiber Woofer
The AT8000’s 8” woofer is constructed of
carbon and glass fibers which are not only
lighter and more rigid than polypropy-
lene, but are interlaced in a pattern that
reduces cone breakup and effectively
lowers distortion.
Hyperbolic Tri-Laminate Dome
Midrange and Zero-Diffraction
Swiveling Tweeter*
The AT8000’s 1-1/2” midrange driver and
1” tweeter both share a tri-laminate design
consisting of an inner textile layer which
forms the dome, a high damping layer to
kill unwanted resonances, and an outside
layer of urethane to add stiffness and pre-
vent breakup modes.
AT8200
Aluminum/Urethane Composite Woofer
The AT8200’s 8” woofer is constructed of a
composite of aluminum and urethane
which is extremely light, highly efficient,
and offers superior damping characteristics.
Hyperbolic Aluminum/Urethane Dome
Midrange and Zero-Diffraction
Swiveling Tweeter*
The AT8200’s 1-1/2” midrange and 1”
tweeter incorporate the same aluminum/
urethane composite used in the construc-
tion of the AT8200’s woofer. The result is a
very natural sounding speaker capable of
reproducing mids and highs with superb
detail and accuracy.
Computer Optimized Crossover with
Acoustical Configuration Controls
The second order Linkwitz-Riley crossover
is computer optimized and constructed of
premium components for unparalleled
sonic performance. The baffle-mounted
Tone Controls provide installers with Bass,
Midrange and Treble adjustment in four
increments (-2dB, Flat, +2dB, +4dB). These
controls can be used to fine tune the speak-
ers performance or to compensate for less
than ideal room acoustics. (For more infor-
mation, see Setting the Tone on page 15.)
BumpBack™ Woofer Magnet
Niles engineers have utilized a unique mag-
net construction allowing far greater “throw”
or voice coil excursion. This enables Niles
AT loudspeakers to play louder without
mechanical distortion or “bottoming”.
