Placement
Acoustic Controls
System 8200e LR speakers include unique acoustic controls to help maxi-
mize their performance in your room. These controls are explained in
greater detail on page 9.
Model 800e C Center Channel Speaker
It is vital to the accurate reproduction of a multi-channel soundtrack that
the three front speakers have the same sonic signature. Therefore, the 8200e
C Channel Speaker contains the same driver complement as its respec-
tive matching LR speakers (see Figure 2). It is designed for use only with
a dedicated subwoofer and includes the same unique acoustic controls
mentioned above.
The 8200e C is designed to be placed horizontally, as opposed to the vertical
positioning intended for the 8200e LRs.
NOTE: The 1" tweeter on the 8200e is mounted in a brushed alumi-
num plate that is visible through the metal mesh grilles. If you prefer
not to see this cosmetic addition, a black diecut foam trim piece is
included for each tweeter plate. Simply peel the paper backing and
carefully align the foam to the tweeter and press on to the alumi-
num plate. Please be aware that the foam piece is not intended to be
removed after attachment.
Models 800e SR Surround Speakers
The Model 8200e SR Dipole/Bipole Surround Speakers (Figure 3) are
intended for use in multi-channel audio/video sound systems only as dedi-
cated side or back surround channel speakers. The 8200e SR utilizes dual
5¼-inch GLH drivers and two of the same tweeters as described above.
The surround speakers can be switched between Dipole and Bipole opera-
tion. These settings are explained on page 10, "Dipole/Bipole Operation of
the SR Speakers. "
NOTE: Although the speakers in the Atlantic Technology Systems
8200e are acoustically and cosmetically matched to each other for
ideal results, they may also be used with other Atlantic Technology
components with extremely satisfying results.
Placement
Speaker/room interactions have a huge impact on the sound of the system.
Moving the speakers just a little can make a dramatic difference in what you
hear. Remember that the best acoustic placement of the speakers will vary
from room to room. Use the following placement guidelines (see page 5) as
a starting point. But also feel free to experiment. In fact, it may be beneficial
to hook up the front LR and surround speakers with some extra wire and
to simply drape the wire across the floor before installing the speakers per-
manently. This will allow you the opportunity to move the speakers around
easily so you can find the best sonic and visual locations.
Home Theater
Remember that the primary goal of a good home theater is not to make you
believe that you are in a movie theater. It's to make you believe you're in the
movie. For a home theater system, place the LR speakers on either side of
the television. The left and right front speakers should be far enough apart
(6 to 10 feet is usually best) that you get a good stereo "image" when they are
playing alone, but not so far apart that the sound seems to be disembodied
from the TV, distracting you from the picture. When using a center channel
speaker, a wider separation of the left and right front speakers is usually pos-
sible. You may chose to "toe" the LR speakers in, aiming them approximately
at the prime listening position. This can be particularly useful if the front LR
speakers are fairly far apart.
IMPORTANT NOTE Try to keep the LR and C tweeters approximately
centered at or aimed at ear level when seated. This is because the align-
ment of the drivers on the front panel results in limited vertical spread of
the mid and high frequency sounds to reduce unwanted floor and ceiling
reflections. If the speakers are too high or too low however, you will miss
a significant portion of the upper middle and high range elements of the
sound. This alignment of the drivers provides enhanced horizontal spread
of the sound making for a much better sound experience for a group of
listeners and reducing the need to sit in a precise "sweet spot."
The center channel speaker should be placed directly above or below your
television. It is important that the speaker is centered on the screen, not off to
the side. The pivoting design of the 8200 C allows you to tilt it up or down so
that the speaker points most directly at the listening position.
Surround Effects and Speaker Locations
The 8200e SR's shape allows great flexibility in placement. Due to their
switchable Dipole/Bipole design, it's possible to place the speakers almost
anywhere within the rear third of the room and get good results. However,
the best location for surround speakers is straight out to the sides of, or
slightly behind the primary listening area, approximately 1-2 feet above
seated ear level to no less than 2 feet down from the ceiling.
As noted above, the surround speakers (as opposed to the back speaker(s)
in a 5.1, 6.1 or 7.1 channel system, see below) are primarily intended to
re-create the ambient sounds taking place in the movie scene. Therefore,
throughout most of a movie or TV program you may not be consciously
aware of output from these speakers. In other words, don't worry if you aren't
hearing the surround speakers. Please try to avoid the trap of turning the
surrounds up and up so that you hear them most of the time. The result will
be a much less believable surround experience.
There are dedicated LEFT and RIGHT model 8200e SR speakers. This is
clearly marked on the back of each speaker. Be sure that the Left side sur-
round speaker is placed directly to the left side of the prime listening area
(facing the screen) and the Right speaker is directly to the right side. As an
easy reference, the Dipole/Bipole switch should always be facing the back of
the room. Should you wish to hang them on the wall, closer than 24 inches
to the ceiling, you should remove and re-install the keyhole hangers upside
down. Then turn the speakers over, hanging them upside down, and swap
them side to side for proper operation.
