SPEAKER PLACEMENT
SUBWOOFER
SURROUND SPEAKERS
FRONT
SPEAKERS
0–2 ft
0–0.6m
The front speakers should be
placed the same distance
from each other as they are
from the listening position.
They should be placed at
about the same height from
the floor as the listeners’
ears will be, or they may be
angled toward the listeners.
The center channel speaker
should be placed slightly
behind the front left and right
speakers, and no more than
2 feet (0.6m) above or below
the tweeters of the left and
right speakers. It is often
convenient to set the center
speaker on top of the televi-
sion set, as shown in the
drawing.
The JBL Cinema Sound
speaker system may be used
in 5.1-,
6.1- or 7.1-channel
applications. In 5.1-channel
applications, two
of the sur-
round speakers should be
placed slightly behind the lis-
tening position and, ideally,
should face each other and
be at a
level higher than the
listeners’
ears. If that is not
possible, they may be placed
against a wall behind the
listening position,
facing for-
ward. In 6.1-channel
applica-
tions, two of the surround
speakers should be placed in
the side positions, and a sin-
gle surround back speaker
should be placed against the
wall behind the listening
position. In 7.1-channel
applications, place
two of the
surround speakers
in the side
positions, and place the two
surround back speakers
against the rear wall.
In Dolby
®
Digital and DTS
®
systems, it is best to aim all
of the speakers (except the
subwoofer) toward the lis-
tening position at or slightly
above about ear-level height.
In systems where only ana-
log surround processing
(such as Dolby Pro Logic
®
II)
is available, it may be prefer-
able to aim the speakers
straight out from the wall to
obtain a more diffuse sound.
The low-frequency material
reproduced by the subwoofer
is mostly omnidirectional,
and this speaker may be
placed in a convenient loca-
tion in the room. However,
bass reproduction will be
maximized when the sub-
woofer is placed in a corner
along the same wall as the
front speakers. Experiment
with subwoofer placement
by temporarily placing the
subwoofer in the listening
position and moving around
the room until the bass
reproduction is best. Place the
subwoofer in that location.
CENTER CHANNEL
SPEAKER
Single surround back speaker
may be used with 6.1 receivers
and processors.
Alternate placement for surround speakers when only 5.1 channels are used; required placement for surround back
speakers in 7.1-channel systems.
