IWCB-727 THX In-Wall Closed Box 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 front three speakers
should be at or just above ear height when seated, just as
with stereo speakers. Try to keep the vertical position of the
three front speakers within 18 inches of each other, as this
will maintain smooth, believable left-center-right pans.
Left Center Right
Subwoofer
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. Direct radiator or dipole/bipole
speakers 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 to 10 feet usually works well.
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
Close Box speakers as surround speakers, mount them
above the listeners’ ears, slightly behind the listening area
either on the side or rear walls. Make sure the DVC is in the
“off ” position.
NOTE: The IWCB-727 is not magnetically shielded. If
you are using them with an old CRT-type television,
be sure they are at least 12 inches away from the pic-
ture tube to prevent video interference.
