INSTALLATION
Speaker Placement
With either multichannel or stereo audio, careful speak-
er placement is important for proper imaging. Imaging is
the ability of the speaker system to reproduce sounds so
they appear to come from between the speakers.
Following are some general placement guidelines for
home theater applications. Other factors to consider for
speaker placement include:
• Suitable wall surfaces for mounting the speakers
• Proximity to room corners
• Locations where speaker cables can be run, either
hidden in the wall or attached to its surface

Home theater

In a multichannel audio system for a home theater, one
LCR7 should be installed horizontally above or below the
video display for the center channel, and two should be
installed vertically to the left and right of the display for
the main front channels.
The center-channel speaker should be as close to ear
level as possible; thus, if the video display is mounted
high, the speaker should be below it. If the display is
low, the speaker should be above it. The speaker should
then be angled up or down as needed so that its axis
points toward the ear level of the listeners.
The left and right speakers can be installed next to the
display or farther apart as desired. They should be angled
inward so their axes point toward the center listener.
For best results, we recommend placing the left and
right speakers so their centers are level with the listen-
ers’ ear height. However, if the video display is centered
above or below ear height, it may be preferable to install
the left and right speakers level with the display for
aesthetic reasons.

Placement near corners

Placing a speaker near a corner of a room can cause
sonic refl ections off the side wall. This can result in a
loss of clarity and poor imaging. Accordingly, we do not
recommend placing the LCR7 near a corner unless the
side wall is covered with sound-absorptive material.
Generally, the best acoustic performance will result if
the left and right speakers are placed in similar positions
on the same type of wall surface.
