Surround Speakers
Front Speakers
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
The center channel speaker
should be placed slightly
behind the front left and right
speakers, and no more than
two feet above or below the
tweeters of the left and right
speakers. It is often convenient
to set the center speaker on top
of the television set, as shown
in the drawing. 
The two surround speakers
should be placed slightly
behind the listening 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 on a wall behind the
listening position, facing for-
ward. The surround back
speaker (in SCS 188 only)
should be placed behind the
listening position, facing the
center speaker. The surround
speakers should not call
attention to themselves.
Experiment with their
placement until you hear a
diffuse, ambient sound
accompanying the main
program material heard in the
front speakers.
The low-frequency material
reproduced by the subwoofer is
mostly omnidirectional, and this
speaker may be placed in a
convenient location in the
room. However, the best
reproduction of bass will be
heard when the subwoofer 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.

The customer is responsible for
proper selection and use of
mounting hardware, available
through hardware stores, to
properly and safely wall-mount
the speakers.
On the wall. Wall brackets
are included.
On optional stands.
Separate and strip the ends of
the speaker wire as shown.
Speakers and electronics
terminals have corresponding
(+) and (–) terminals. Most
manufacturers of speakers and
electronics, including JBL, use
red to denote the (+) terminal
and black for the (–) terminal.
The (+) lead of the speaker wire
is noted with a stripe. It is
important to connect all
speakers identically: (+) on the
speaker to (+) on the amplifier
and (–) on the speaker to (–) on
the amplifier. Wiring “out of
phase” results in thin sound,
weak bass and a poor stereo
With the advent of multichannel
surround-sound systems,
connecting all of the speakers
in your system with the correct
polarity remains equally
important in order to preserve
the proper ambience and
directionality of the program
