Attaching the Grilles
The included metal grilles are held to the front of the enclosures with powerful neodymium magnets. There are depressions on the back of the grille
that the magnets fit into. Once the speakers are in their final position. Position the grille over the magnets on the baffle. (See Figure 1) Move them
together slowly and when you get close enough, the magnets will draw the
grille in and hold it tight. Be careful not to get your fingers caught between
the grille and the cabinet.
NOTE:
You will notice a threaded insert onthe back of the LR satellites and SR surrounds. This is for bolting the satellites to speaker
stands that utilize a slotted L-bracket. Use a ¼” x 20 bolt to secure
the speaker to the stand.

Model 1400 LR and 2400 LR
Front Channel Speakers
The Model 2400 LR Front Channel Speakers (Figure 1) are high-performance 2-way systems intended for use with a quality subwoofer, such as the
Atlantic Technology Model 224 SB, 334 SB or 444 SB box-type subwoofer.
Each speaker contains two GLH (Graphite Loaded Homopolymer) 4 ½”
(115mm) woofers and an advanced 1” (25mm) Low Resonanace Tweeter
(LRT™) 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 1400 LR speakers are very similar to the 2400 LR speakers, except
they employ one 4 ½" GLH woofer instead of two.
Model 1400 C and 2400 C Center Channel Speaker
For accurate reproduction of a multi-channel soundtrack, the three frontchannel speakers must have the same sonic signature. Therefore, the 1400 C
and 2400 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 1400 C and 2400 C includes unique acoustic controls to help maximize its performance in your room. These controls are explained in greater
detail on page 8.
Model 1400 SR-z and 2400 SR Surround Speakers
The Model 2400 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 2400 SR enclosure has two
4 ½” (115mm) GLH woofers and two of the same high performance soft
dome tweeters found in the 2400 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, the model 1400 LR makes an excellent surround speaker. When using it 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 1400
and 2400 are acoustically and cosmetically matched to each other for
ideal results, they may also be used with other Atlantic Technology
components and a wide variety of speakers from other manufacturers
with excellent results.

Placement
System 1400 and 2400 High Performance Loudspeakers
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 opposite
page) 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 permanently. 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 three front channel speakers (LR and C) are magnetically
shielded so they will not interfere with your television picture. The left and
right front speakers should be far enough apart (6 to 10 feet, 2-3 meters,
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 possible.
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
mately the same height and aimed at ear level when seated. This is
because we’ve designed the alignment of the drivers on the front
panel to limit the vertical spread of the mid and high frequencies,
thereby reducing the floor and ceiling reflections that adversely affect
sound quality. 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.”
Try to keep the LR and C tweeters at approxi-
Surround Effects and Speaker Locations
The 2400 SR’s shape allows great flexibility in placement. Due to the 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, or slightly
behind the primary listening area, approximately 1-2 feet (.3-.6m) above
seated ear level, but no closer than 2 feet (.6m) from the ceiling. As noted
above, the surround speakers (as opposed to the back speaker(s) in a 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 1400 SR-z and 2400 SR speakers. This is clearly marked on the back of each speaker. Be sure that the Left
side surround 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.
7.1 Channel Systems
For best performance in a 7.1 channel system, we recommend using
another pair of 1400 or 2400 LR's on the back wall, and 2400 SR's on the
side walls.
If you are setting up a system that uses back surround speaker as well as
side surrounds (Dolby Digital 7.1, DTS ES, etc.) you can choose to use either
SR model speakers in Dipole or Bipole mode or another pair of front LR
speakers in the back of the room. If the 2400 SR’s are used as back surrounds
in a 7.1 channel system, they should be installed with the Right speaker
placed over the listener's left shoulder and the Left speaker placed over the
listener's right shoulder. About one-third of the way out from the corners in
most rooms is a good starting point.
If you are using a THX Ultra 2 certified controller/receiver, you should place
the back surround speakers approximately 1 to 2 feet (.3-.6m) apart in the
center of the back wall. The special circuitry in the processor will help to
create a believable and effective surround field using this placement. Please
read the electronics manual to learn more about this placement option.
