In-Wall Left, Center, Right
Congratulations on your purchase of SpeakerCraft’s AIM LCR Speakers. The AIM LCRs have been timbre
matched to SpeakerCraft’s MT and CRS series Speakers, providing an outstanding home theater experience.
AIM LCR speakers can be used in any position of a home theater speaker system. A single AIM LCR can be used for the front
center channel, or a pair can be used for front or rear left and
right. Because the AIM LCR speakers are magnetically shielded,
it is perfectly safe to place them close to the television.
Use as a Center Channel Speaker
The AIM LCR has been designed to blend seamlessly with all
SpeakerCraft architectural in-wall and in-ceiling speakers. With
the cabinet positioned horizontally, install the AIM LCR into the
wall as close to the screen as possible. This most often means
it will need to be installed just above or below the television.
Vertically lining up the cabinet with the left and right speakers
while not necessary, will improve the performance. (Figure 1)
Use as Front Left and Right Speakers
When using AIM LCRs for front left and right speakers, the cabinets should be positioned vertically with the tweeter towards the
screen. (Figure 1)
Figure 1
Best results are achieved when the left, right and center channel speakers are all the same distance away from the listener.
The front left and right speakers should be placed so that they
form an equilateral triangle, with the listener at one point and
each speaker at the other two. (Figure 2) Ideal sound will be
achieved when the tweeters are placed at ear level or slightly
higher. If the speakers are positioned far away from the primary
listening area, adjust the pivoting tweeters so they are pointed
toward the primary listening area. NOTE: To avoid possible
damage to the pivoting tweeters, read the section entitled
“SPEAKER ADJUSTMENTS” in this manual prior to performing
the tweeter adjustment.

Before installing your speakers into the wall, you should consider the placement carefully, taking into account the location of electrical, plumbing and other fixtures. Contact your dealer for assistance if you are not sure of the best location
in your particular room environment.

New Construction – Unfinished Walls
A New Construction Bracket (available from your dealer), may be installed prior to drywall application across studs (up to 24" on-center) where
a speaker will be located. Insulation material should be in place prior to installing drywall. After the hole is cut and the drywall is installed, the
speakers are then easily installed following the instructions for mounting in “Finished Walls” below.
Finished Walls
Prior to the actual installation of the speakers, it will be necessary to run cables to the speaker locations. See your dealer for more information
about cable installation. After the cable has been properly installed, you are ready to mount the speakers. Following the simple steps listed
below will result in a professional looking installation:
1. Determine the best area to mount your speakers. This area of the wall should be free of obstructions such as electrical conduit, HVAC ducts,
or water lines. This can best be determined by noting the placement of fixtures and gaining access to an attic or crawl space for further
analysis of the location of such obstacles.
2. Find the studs nearest the desired speaker mounting location. We highly recommend using a good stud-finder tool for this procedure. If
you are lining up the speakers to some other object or molding in the room, make sure you consider the size of the baffle flange which
extends beyond the mounting hole on all four sides.
3. Mark the hole. A template for setting the hole is provided in the box (along with two paint mask inserts for use when painting). Position the
template in the desired position and pencil an outline on the wall.
4. Cutting the hole. CAUTION: This is the most important part of the entire installation. If you
are not certain whether any obstructions exist behind the desired mounting area, you should
start by cutting a small hole in the center of your penciled mounting hole with a drywall saw.
Cut at a 45º angle towards the inside of the hole (Figure 3). Cutting the small hole at this
angle will make drywall repair much easier as the piece cut out can be installed neatly back
into the hole. Once you have determined there aren’t any obstructions in your desired mounting location, start cutting the finished hole at a 90º angle to the wall surface.
5. Add insulation. If the area in the wall is not already insulated, add an adequate amount of
insulation material to fill the wall cavity. If the insulation material used is faced with foil or paper,
position the foil or paper away from the speaker.
Figure 3
The unique integral six foot mounting system incorporated into each AIM LCR speaker allows for a
quick installation by following these easy steps:
1. Remove the grille. It may be necessary to push one or two of the mounting screws and its
attached foot towards the baffle and against the inside surface of the grille to force the grille out
of its retaining groove.
2. Attach the speaker cable (observing the proper polarity with your amplifier, + to + and – to –).
Make sure the left channel of the amplifier is connected to the left speaker, and the right channel is connected to the right speaker.
3. Make sure the mounting feet are turned inward to clear the opening, and insert the speaker
into the ceiling. Position the speaker into the hole. NOTE: The flange of the speaker is designed
to flex and conform to any small imperfections in the ceiling’s surface. Tighten the six screws on
the front of the baffle only enough to make the flange become snug against the ceiling. As you
tighten the screws, the feet will automatically flip into an outward position (Figure 4), thereby
clamping the drywall between the feet and the flange. CAUTION: Over tightening may warp
the baffle, crack the ceiling, cause flange to distort, and make the grille difficult to install.
4. Push the grille firmly into the slot in the speaker baffle.

Pivoting Inner Baffle Adjustment
Your AIM LCR Series speakers come from the factory with the inner baffles facing straight. This will result
in the overall smoothest response. However, depending on your particular primary area, room acoustics,
ceiling height, or personal preference, you may find the sound more pleasing by pointing the inner baffle
in a particular direction. If additional sound is desired in the primary listening area, pivot the inner baffle
towards that area; and if less sound is required, pivot the inner baffle away. Using both hands, push the
ridged triangle areas located at each corner of the baffle to point it in the desired direction. (Figure 5).
Pivoting Tweeter Adjustment
Your AIM LCR Series speakers come from the factory with the tweeter facing straight out from the baffle.
This will result in the overall smoothest response. However, depending on your particular primary area,
room acoustics, ceiling height, or personal preference, you may find the sound more pleasing by pointing
the tweeters in a particular direction. If additional treble is desired in the primary listening area, point the
tweeter towards that area; and if less treble is required, point the tweeter away. Push gently at the edge
of the tweeter to point it in the desired direction. (Figure 6) CAUTION: Avoid touching tweeter dome as
damage WILL occur on metal dome tweeters (AIM LCR 3 only).
For home theater use, we recommend the following tips:
Figure 5
• If the speakers are being used as main front channels, the AIM LCR should be angled towards the listener.
• If the speakers are being used for rear surround channels, you may wish to pivot the AIM LCR away
from the listener to achieve a more diffused sound.

Treble Adjustment (AIM LCR 3):
The switch labeled TREBLE allows for 6dB of tweeter adjustment. Your speakers were shipped with the
Treble switch in the ”+” position, providing +3dB of treble. If you want less treble, slide the switch to the
“–” position and the tweeter will play –3dB of treble. (Figure 7)
Bass Adjustment (AIM LCR 3):
The switch labeled BASS allows for 6dB of bass adjustment. Your speakers were shipped with the Bass
switch in the ”+” position, providing +3dB of bass and an impedance of 6 ohms. If you want less bass,
slide the switch to the “–” position and the woofer will play –3dB of bass and increase the impedance to
8 ohms. (Figure 8)
Figure 6
Remember that altering the impedance affects the number of speakers able to be driven by an amplifier. If
multiple pairs of speakers are to be driven by one amplifier, SpeakerCraft suggests using the lowest output
position (switch set to the “–” position) until it is determined that the amplifier will operate properly with
the speakers switched to a higher output mode. If you want to safely operate multiple pairs of speakers,
consider purchasing SpeakerCraft S4 or S8 Speaker Selectors.
Figure 7
If you plan to paint your speakers, we recommend that it be done prior to installation. If you plan to
paint your speakers sometime in the future, it is best to remove them by simply reversing the steps for
“SPEAKER INSTALLATION” on page 2. If it is necessary to paint the speakers while they are still in the ceiling, the paint masks provided in the carton must be installed in place of the grille while the flange is being
painted with the ceiling. The grilles can also be painted, however, great care should be taken not to clog
the holes, as this will greatly reduce the sound quality of the speakers. SpeakerCraft recommends only
light spray painting using 5 parts thinning agent to 1 part paint. Do not paint the grilles while they are
attached to the speaker. If it is necessary to paint the under grille material, follow the same procedure used
to paint the grilles.
