IW-155 LCR THX Ultra2 In-Wall Thin Bezel LCR Speaker
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 verti-
cal position of the three front speakers within 18 inches
of each other, as this will maintain smooth, believable
left-center-right pans.
The spacing of the left-right speakers can be a little wider
than with 2-channel stereo speakers, since in a theater
system, 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 IW-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 per-
formance we strongly recommend Atlantic Technology
Dipole or TriVector™ surround speakers. If you are using
our dedicated surround speakers please follow the place-
ment recommendations 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 Theater System speakers as surround speakers,
mount them above the listeners’ ears, slightly behind the
listening area either on the side or rear walls.
