SPEAKER PLACEMENT
Front Speakers
Surround 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
listeners.
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.
Center Channel Speaker
0 – 0.6m (0 – 2 ft.)
150-180 cm
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 forward. 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.
Subwoofer
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.
