SPEAKER ADJUSTMENTS
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 baf-
fle. 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 touch-
ing tweeter dome as damage WILL occur on metal dome tweeters (AIM LCR 5 & AIM LCR 3).

For home theater use, we recommend the following tips:
• 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 Five & 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.

Bass Adjustment (AIM LCR Five & 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)

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)
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.

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.

AcoustaCell 8 SYSTEM
The AcoustaCell 8 System (P/N ASM87800), sold separately, is an option for retrofit installations.
AcoustaCell dampens the wall cavity and improves AIM LCR speaker performance. Installation can
be easily done at the time you are ready to mount the AIM LCR speakers. Please see the manual
included with AcoustaCell 8 for installation instructions.
