IWTS-155 LCR In-Wall THX Ultra2 Theater System Speakers
Home Theater Placement
Home Theater Systems
Today’s home theater systems require you to place six or
more speakers in your room. For the most convincing
theater effects, speaker placement must be very carefully
thought out. This is especially true with in-wall speakers,
since their installation is permanent!
Left/Center/Right Locations The tweeter in the front three
speakers should be at or just above ear height when seated,
just as with stereo speakers. Try to keep the vertical posi-
tion of the three front speakers within 18 inches of each
other, as this will maintain smooth, believable left-center-
right pans.

Front Speaker Array should be
placed as close to ear level as
possible.
Optional Dipole/Bipole
Speakers should be
placed directly to the
sides of the seating area
and approximately
1-2 feet (.3-.6 meter)
above the listener’s ear
level.
Optional Surround Back Speakers
should be placed approximately 1-2
feet (.3-.6 meter) above the listener’s
ear level. Dipole or direct radiators
may be used here.
Optional Direct Radiator Speakers
should be placed slightly behind the
listening position, above ear level.
The spacing of the left-right speakers can be a little wider
than with 2-channel stereo speakers, since in a theater sys-
tem, the center channel speaker reproduces the on-screen
effects and anchors the center image. Left-right spacing of
about 8 to10 feet usually works well.
NOTE:
The IWTS-155 LCR is not magnetically
shielded. If you are using it with an old-styled CRT-
type television, be sure the speakers are located at
least 12 inches away from the picture tube to prevent
video interference.
Surround Speakers In order to achieve optimum perfor-
mance we strongly recommend Atlantic Technology Dipole
or TriVector™ surround speakers. If you are using our dedi-
cated surround speakers please follow the placement recom-
mendations included in their installation instructions.
Non-Dipole Surrounds The most realistic surround effects
occur when the listener can’t localize the actual location of
the surround speaker. If you decide to use the In-Wall The-
ater System speakers as surround speakers, mount them
above the listeners’ ears, slightly behind the listening area
either on the side or rear walls.
