Installing the Speaker, Dsfg The Basics

Installation of the Speaker and Grille in New or Existing Construction

Installing the Speaker

If the grille is already installed, remove it by using a bent paper clip or the tip of a corkscrew and pulling it away from the frame (See Figure 18).

1.Separate the speaker wire so that at least two inches of each conductor are free.

2.Strip one half inch of insulation from the end of each conductor of the speaker wire.

3.If you have gold pin connectors which you wish to use, affix them to the stripped wire ends now.

4.Connect one stripped wire end (or con- nector) to the black and one to the red terminal. Pay attention to the markings on the wire. Each speaker must be con- nected to the amplifier in the same way.

5.Place the speaker baffle in the frame and secure it with the supplied #8 x 1/2” screws. If you find that the baffle does not smoothly fit the frame, slightly loosen the mounting screws that hold the frame to the bracket.

6.Carefully fit the grille into its recess so that it is barely in place. Starting with one corner, go around the speaker, pushing the grille in a little bit each time. You should be gentle, the aluminum grille can be easily bent out of shape. The speaker will have an absolutely flush appearance when it is fully in place.

DSFG - The Basics

As explained in the Features and Benefits segment of this manual, the acoustic inter- action between the two midrange drivers and the offset tweeter results in the flattest frequency and phase response approximate- ly 15 degrees off-axis from the tweeter. This unique driver configuration is combined with the rotating and pivoting design of the Midrange/Tweeter Array to enable the installer to “steer” the sweet spot towards the listening position (See Figure 19).

Positioning the

Midrange/Tweeter Array

Proper adjustment of the Midrange/Tweeter Array is essential to getting the best sound from your AT8500 and AT8700 speakers. Just as freestanding speakers sound their best when angled inward (or “toed in”), position- ing your AT speaker’s Midrange/Tweeter Array with the offset tweeter furthest from the listener will steer the sweet spot in towards the listening position at approxi- mately 15 degrees off axis. Pivoting the Midrange/Tweeter Array on it’s own axis will enable you to accurately focus the sweet spot on the listener relative to their distance from the speakers. “Toeing” in the Array too tightly will cause the image to focus in front of the listener, while toeing them too far out will cause the middle of the sound stage to disappear or sound unbelievably wide and unrealistic. Experiment with your favorite recordings until you find what works best in your installation.

AT8500, AT8700 specifications

Niles Audio, a renowned name in the audio industry, has introduced its AT series amplifiers, notably the AT8700 and AT8500 models. These amplifiers are designed to deliver high-performance audio for residential and commercial installations, ensuring an enhanced listening experience for users.
