Model 2200 SR Surround Speakers

The Model 2200 SR Dipole/Bipole Surround Speakers (Figure 3) are intendedforuseinmulti-channelaudio/videosoundsystemsasdedicated 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 explainedonpage8,“Dipole/BipoleOperationof theSRSpeakers.”

Becauseof theirsmallsize, boththemodel920LRand1200LRmakean 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 listeningarea.MounttheLR'sonthesidewalls,aboveandslightlybehind thelisteningposition(Seepage5).

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 Technology components and a wide variety of speakers from other manufacturers with excellent results.

You may chose to“toe” the LR speakers in,aiming them approximately at theprimelisteningposition.Thiscanbeparticularlyusefulif thefrontLR

speakersarefairlyfarapart.

IMPORTANT NOTE Try to keep the LR and C tweeters at approximately 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.”

Surround Effects and Speaker Locations

6.1 and 7.1 Channel Systems

For best performance in a 7.1 channel system, we recommend using anotherpairof 920,1200or2200LR'sonthebackwall,and2200SR'son thesidewalls.

If you are setting up a system that uses back surround speaker(s) as well as side surrounds (Dolby Digital EX,DTS ES,etc.) you can choose to use eitherSRmodelspeakersinDipoleorBipolemodeoranotherpairoffront LRspeakersinthebackof theroom.If the2200SR’sareusedasbacksurrounds in a 6.1 or 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; these back surrounds should be placedapproximately150degreesfromthescreenonthebackwall.About one-third of the way out from the corners in most rooms is a good startingpoint.
