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.

Individual Component Descriptions

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.
