In-Wall at Ear Level

The AT8500 and AT8700 speakers will per- form their best when installed at ear level and spaced within the “good placement zone for music” (See “Speaker Placement” on page 5). Position the Midrange/Tweeter Array in the vertical position with the tweeter on the outside and pivot the Array in or out to obtain a believable soundstage

(See Figure 20).

In-Wall at Above Ear Level

When the speakers are located up high in the walls, installing the speakers upside down with the Midrange/Tweeter Array as close to ear level as possible will yield the best results. Depending on the distance between the speakers, position the Midrange/Tweeter Array and pivot the dri- vers so that the sweet spot is focused on the listening position (See Figure 21).

Coverage for Large Listening Areas When installing your AT8500 or AT8700 speakers in large rooms with varying listen- ing positions, best results will be achieved by widening the dispersion pattern of the Midrange/Tweeter Array. Installing the speakers up high in the wall and spacing them appropriately will provide even cov- erage over a larger area. Position the Array at a 45 degree angle to achieve maximum coverage. Some critical listeners may notice that positioning the Array in this manner may blur the stereo image slightly, but the size of the listening area will be dramatical- ly increased so other listeners may enjoy the music (See Figure 22).

AT Speakers for Home Theater

The AT8500 and AT8700 speaker models are designed to perform as well for movies as they do for music. Position the Midrange/ Tweeter Array for the main left and right speakers as you would for music listening. If you are using an AT8500 or AT8700 for your center channel speaker, it may be installed horizontally or vertically above a TV, above or below a standard projection screen, or behind a perforated screen at ear level. Position the Midrange/Tweeter Array verti- cally for maximum coverage and pivot the drivers approximately 15 degrees off axis for the flattest phase and frequency response. Because the AT8500 and AT8700 speakers are not magnetically shielded, be sure to maintain a distance of at least 24 inches from a direct view TV to avoid discoloring the pic- ture (See Figures 3 and 4 on pages 6 and 7).
