Features and Benefits

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). Additionally, the AT8700 features a Sub- Bass Boost control which adds 3dB at 60Hz to enhance the speaker’s low frequency performance if desired, and two Linear Track™ Filters. These controls can be used to fine tune the speakers performance or to compensate for less than ideal room acoustics. (For more information, see Setting the Tone Controls on page 20).

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”.

6 mm Polycarbonate X-Matrix™

Reinforced Baffle

The AT8500 and AT8700 models feature an extra thick (6mm) polycarbonate, X-Matrix baffle design which uses specially molded ribs to add rigidity to the baffle assembly. The end result is better bass and improved midrange detail.

Weather Resistant Construction

The AT8500 and AT8700 loudspeakers fea- ture drivers which are impervious to mois- ture; the grille (sold separately as part of the AT8000 Series Frame and Grille kit) is made of aluminum, and all exposed hard- ware is constructed of stainless steel.

Absolutely Flush to the Wall

Appearance

The unique mounting system of the AT loud- speakers securely clamps the frame to the bracket, sandwiching the wall material between them. Because the clamping action is totally uniform around the frame, there are no shadows or gaps between the wall and the frame. Additionally, the Niles mounting sys- tem is carefully optimized to stiffen the sur- rounding drywall and prevent it from resonat- ing. You hear only the music, not the drywall.

Easy Retrofit Installation in your Existing Home

Designed for ease of installation, the Niles mounting system makes retrofit installa- tions simple and fast. A supplied template assures fast and accurate hole cutting. The bracket slips behind the drywall and the screws secure the bracket to the frame, sandwiching the drywall between them. The speaker baffle attaches to the frame, and the grille mounts over the speaker.

Three Stage Installation System for Remodels or New Construction

You install only the parts you need for a par- ticular stage of construction. When the fram- ing and wiring are finished, you install the bracket. After the drywall is up, but before the painter begins to paint, you install the frame and provide the painter with the alu- minum grilles so that they can be painted to match the surroundings. Only when con- struction is completely finished do you put the valuable speaker in the wall. You don’t have to mask or prep the speaker for paint- ing, and worries about theft during the final phases of construction are never an issue!

Eight Ohm Impedance

The AT8500 and AT8700 speakers are designed to be compatible with most ampli- fiers. Their eight ohm impedance is an easy electrical load for most amplifiers to drive.

Low Diffraction, Paintable

Aluminum Grilles

AT speakers are available with aluminum grilles. The powder-coated aluminum grille has hundreds of precisely sized perforations, creating an acoustically transparent grille.

Infrared Sensor Mount

The speaker baffle has a locator designed for the Niles MS-1 MicroSensor,™ a miniature infrared sensor. The MS-1 installs discretely behind the aluminum grille and therefore minimizes wall clutter in your home. When you want to control your equipment, you simply point your remote control at the speaker from up to 15 feet away.
