SPEAKER INSTALLATION
The unique integral four foot mounting system incorporated into each speaker
allows for quick installation following these easy steps:
1. If the grille is on the speaker, remove it. 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: +
(red speaker input) to + and – (black speaker input) 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 surface. Tighten the 4 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 (See Figure 4),
clamping the drywall between the feet and the flange.

PAINTING THE SPEAKERS
If you plan to paint your speakers, we recommend that it be done prior to installation. If you decide to paint your speakers
sometime in the future, it is best to remove them by simply reversing the steps for SPEAKER INSTALLATION listed above. When
painting the speakers, the paint masks provided in the carton must be installed in place of the grille. 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. Before painting the grilles, remove the material under grille. Place this material back in place once the grille has
been painted. 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 material under the grille, follow the same
procedure used to paint the grilles.

ADJUSTING THE FREQUENCY RESPONSE
The output of the tweeter on the AccuFit CRS7 Three can be adjusted to suit any environment. In general, we recommend
leaving all of the adjustments at the flat (0dB) setting. To determine which settings will be appropriate for your speakers, you
may need to experiment until the desired sound is achieved.
Selecting the Treble Setting on AccuFit CRS7
To select a setting, simply use a finger to move the switch mounted on the inner side of the speaker to the desired setting
(See Figure 5).
CAUTION: Over tightening may warp the baffle, crack the ceiling, cause the flange to distort, and make the grille difficult to install.
Frequency Settings
When selected, the settings will have the following result:
-3dB: Reduces the loudness of the selected frequency
0dB: The selected frequency remains at neutral level
+3dB: Increases the loudness of the selected frequency
