INTRODUCTION
Congratulations on your purchase of SpeakerCraft’s AIM LCR3 Home Cinema Speakers. The AIM
LCR3s have been timbre matched to SpeakerCraft’s AIM8 , AIM7, MT and CRS Speakers, providing
an outstanding home theater experience.
FIGURE 1
SPEAKER PLACEMENT
AIM LCR3 speakers can be used in any position of a home theater speaker system. A single AIM LCR3
can be used for the front center channel, or a pair can be used for front or rear left and right.
Use as a Center Channel Speaker
The AIM LCR3 has been designed to blend seamlessly with all SpeakerCraft architectural in-wall and
in-ceiling speakers. With the cabinet positioned horizontally, install the AIM LCR3 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)
FIGURE 2
Use as Front Left and Right Speakers
When using AIM LCR3s for front left and right speakers, they should be positioned vertically with the
tweeter towards the screen. (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.
INSTALLATION CONSIDERATIONS
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.

MOUNTING SURFACE PREPARATION
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.
SPEAKER INSTALLATION
The unique integral six foot mounting system incorporated into each AIM LCR3 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.
SPEAKER ADJUSTMENTS
Pivoting Inner Baffle Adjustment
Your AIM LCR3 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 LCR3 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.
For home theater use, we recommend the following tips:
• If the speakers are being used as main front channels, the AIM LCR3 should be angled towards the
listener.
FIGURE 7
• If the speakers are being used for rear surround channels, you may wish to pivot the AIM LCR3 away
from the listener to achieve a more diffused sound.
Treble Adjustment (AIM LCR3 Five & AIM LCR3 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)
PAINTING THE SPEAKERS
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.
