Introduction, BumpBack Woofer Magnet | Niles Audio AT8000, AT8200

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”.
