plaCement of tHe front CHannel SpeaKerS
A home theatre system includes three loudspeak-
ers placed across the front of the listening room.
The distance between the left and right speakers
determines the width of the stereo image. If
the speakers are placed too close together, the
image will be too narrow; too far apart and the
blend will suffer, creating a hole in the middle.
When properly placed, your speakers will create
a continuous “virtual image” from left to right,
with an illusion of sound outside, in front of, and
behind the speaker systems.
We recommend an angular separation between
45 degrees and 60 degrees (when viewed from
above). At the minimum 45° separation the
distance between the speakers is 75% of the
distance from the speakers to the listener. At the
maximum 60° separation the distance between
the speakers is equal to the distance from the
speakers to the listener.
Creating a seamless sound image across the front of the speakers requires careful placement.
The distance from the left, right, and center channel speakers to the listener location should be
as close to equal as possible.
The front channel speakers should be installed so the height of the midrange/tweeter module
is as close as possible to the height of a seated listener’s ears. Try to keep the front channel
tweeters within two vertical feet of that height.
tIp: Our ears use high frequencies to locate the
source of a sound. When the IC-B7S or IC-C7S
are used for the front left and right speakers
in a system, the orientation of the midrange/
tweeter array significantly effects the width
of the stereo image. Changing the orientation
of the speakers changes the separation of the
midrange/tweeter module by 18 inches. Use
this if necessary to get the ideal separation and
stereo image.
