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,
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).
