Complement® On-Wall LCR Loudspeaker
Instruction Manual
INTRODUCTION
Product Description
The Complement® LCR7 Loudspeaker is a wall-mounted
unit for home theater and stereo audio applications. Its
slender profi le is designed to complement the appearance of most fl at-panel video displays. The speaker
comes with two different-colored grilles to coordinate
easily with the room décor or other equipment.
In a home theater, the LCR7 is intended for use in the
front left, center, and right positions adjacent to the
video display. In stereo audio applications, a pair of LCR7
speakers can be used for the left and right channels.
Patent-pending Super Bessel Array™ technology in the
LCR7’s design improves sound dispersion. A special circuit in the speaker alters the response of certain drivers
at certain frequencies. This improves directivity at higher
frequencies, thus helping to broaden the listening area
when the speaker is mounted horizontally for use in the
center position.
The benefi t is that one speaker model can be used for
the three front channels in a home theater. This provides
identical voicing in all three positions, which improves
clarity and imaging.
Because the LCR7 is magnetically shielded, it can be
used next to CRT televisions without causing picture
distortion.
The LCR7 features an array of six mid/low-frequency
drivers coupled with a single high-frequency driver
to reproduce most of the audio spectrum. Its nominal
impedance is 6 ohms. A separate subwoofer is recommended to reproduce the lowest frequencies.
Surround speakers
Although intended primarily for use as front speakers,
the LCR7 can also be used as surround speakers in a
multichannel audio system. As an alternative, any Russound in-wall or in-ceiling speaker would work well for
the surround channels.
Subwoofer
Russound’s Complement Series subwoofers are ideal for
use with the LCR7 to extend the bass response of the
system. We recommend setting the subwoofer’s crossover frequency at 100 Hz.

INSTALLATION
Speaker Placement
With either multichannel or stereo audio, careful speaker 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 listeners’ 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.
