Model 920,1200 and 2200 LR
Front Channel Speakers
The Model 2200 LR Front Channel Speakers (Figure 1) are high-perfor-
mance 2-way systems intended for use with a quality subwoofer, such as the
Atlantic Technology Model 920 SB, 212 SB or 422 SB box-type subwoofer.
Each speaker contains two GLH (Graphite Loaded Homopolymer) 4 ½”
(115mm) woofers and an advanced 1” (25mm) ferrofluid-cooled, damped
soft dome tweeter with a powerful neodymium magnet structure. The
drivers are configured in an M-T-M array (midrange-tweeter-midrange
alignment) This vertical arrangement of drivers provides wide left to right
coverage of sound while limiting the floor and ceiling reflections that may
color the sound. These components are mounted in an acoustically inert
MDF enclosure. The LR speakers are magnetically shielded so they may be
placed close to a TV set without concern.
Model 1200 LR speakers are very similar to the 2200 LR speakers, except
they employ one 4 ½" GLH woofer instead of two.
The Model 920 LR speakers are a scaled down verion of the 1200 LR speak-
ers and employ a single 4" driver but the same tweeter as both the 1200
and 2200 LR's.
Model 1200 C and 2200 C Center Channel Speaker
For accurate reproduction of a multi-channel soundtrack, the three front-
channel speakers must have the same sonic signature. Therefore, the 1200 C
and 2200 C Center Channel speaker utilize the same driver elements as
the respective matching LR speakers (see Figure 2). These speakers are
designed to be placed horizontally. They are also magnetically shielded and
can be placed directly adjacent to your TV set with no adverse effects on
the television’s picture. Both can be tilted on their dedicated base to provide
optimum sonic coverage of the listening area.
Acoustic Controls
System 1200 C and 2200 C includes unique acoustic controls to help maxi-
mize its performance in your room. These controls are explained in greater
detail on page 8.
Model 2200 SR Surround Speakers
The Model 2200 SR Dipole/Bipole Surround Speakers (Figure 3) are
intended for use in multi-channel audio/video sound systems as dedicated
side or back surround channel speakers. The 2200 SR enclosure has two
4 ½” (115mm) GLH woofers and two of the same high performance soft
dome tweeters found in the 2200 front speakers. The surround speakers
can be switched between Dipole and Bipole operation. These settings are
explained on page 8, “Dipole/Bipole Operation of the SR Speakers.”
Because of their small size, both the model 920 LR and 1200 LR make an
excellent surround speaker. When using either LR as a surround speaker,
the best results will be obtained if the speakers do not aim directly at the
listening area. Mount the LR's on the side walls, above and slightly behind
the listening position (See page 5).

NOTE:
Although the speakers in the Atlantic Technology Systems 920,
1200 and 2200 are acoustically and cosmetically matched to each
other for ideal results, they may also be used with other Atlantic Tech-
nology components and a wide variety of speakers from other manu-
facturers with excellent results.
