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 Try to keep the LR and C tweeters at approxi-

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 ele-

ments of the sound. This alignment of the drivers provides enhanced

horizontal spread of the sound making for a much better sound expe-

rience for a group of listeners and reducing the need to sit in a pre-

cise "sweet spot."

Surround Effects and Speaker Locations

The 2200 SR's shape allows great ﬂexibility in placement.Due to the switch-

able 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 speak-

ers.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 sur-

round experience.

There are dedicated LEFT and RIGHT model 2200 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.

6.1 and 7.1 Channel Systems

For best performance in a 7.1 channel system, we recommend using

another pair of 920, 1200 or 2200 LR's on the back wall, and 2200 SR's on

the side walls.

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

either SR model speakers in Dipole or Bipole mode or another pair of front

LR speakers in the back of the room.If the 2200 SR's are used as back sur-

rounds 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

placed approximately 150 degrees from the screen on the back wall.About

one-third of the way out from the corners in most rooms is a good start-

ing 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.
