Congratulations on purchasing SpeakerCraft’s AccuFit CRS7 Series of architectural loudspeakers. The AccuFit CRS7 Series
features a shallow 2 3⁄4" sealed steel enclosure. Speakercraft offers the AccuFit Series to address space limitations, building
codes, sound transfer to adjoining walls and living environment concerns. The AccuFit CRS7 Series of shallow depth, fully
enclosed speakers ensure that the drivers have the proper amount of air space to deliver the best performance regardless
of the installation environment. This new line of technical advanced speakers was designed to fit just about any installation
When following the below recommendations, please keep in mind that placement is always in the ceiling. AccuFit CRS7
speakers can be used as a pair for stereo listening, or for all five channels of a home theater system: front left and right,
center, and rear left and right.
SpeakerCraft recommends the use of a qualified custom installation specialist when installing your AccuFit CRS7 speakers. If
you need assistance in locating an installer, please contact SpeakerCraft at 1-800-448-0976.
1. Determine Your Primary Listening Area
The area where you will most likely be sitting when listening to your speakers is your primary listening area.
2. Placement of Stereo Pair / Front Channels for Home Theater
Consider how far apart the speakers should be. To do this, think of your listening area as one tip of a triangle with each
leg of the triangle being equal. See speakers FL (front left) and FR (front right) in Figure 1. Place the speakers as close as
possible to the two points they represent on the triangle.
If the speakers are to be part of a home theater speaker system, they should be placed as close as possible to the area
above the screen. However, in some cases it may be better to place the speakers farther away from the screen in order
to maximize speaker separation. An example of a case when this would be desirable is when the television is positioned
directly in a corner (See Figure 2).

3. Placement of Center Channel for Home Theater
Place the center channel speaker in line between the front left and right speaker directly above the screen. See C (center) in Figure 1.
4. Placement of Rear Channels for Home Theater
Rear channels should be placed behind the listening area. See RL (rear left) and RR (rear right) in Figure 1.
5. Checking for Obstructions
Before confirming the placement of the speakers, you should carefully consider the location of ceiling joists, electrical,
plumbing and other fixtures that may get in the way. If you are installing the speakers into an existing ceiling, you can
locate obstructions by noting the placement of fixtures and, if possible, gaining access to an attic or crawl space for further analysis. A good stud-finder, found at any building supply store, will help you determine where the joists are located
in the ceiling.
Prior to the actual installation of the speakers, it will be necessary to run cables to the speaker location. See your Authorized
SpeakerCraft dealer for more information on cable installation. After the cable has been installed, you are ready to mount
the speakers.
Preparation for and mounting of the speakers can happen at two different stages. If you are building a new ceiling, follow
the section titled INSTALLATION PREPARATION - NEW CONSTRUCTION. If you are placing the speakers into an existing ceiling,
follow INSTALLATION PREPARATION - FINISHED CEILING. There are different considerations for each application. Please carefully follow the recommendations for your application.
When installing the speakers into a newly built ceiling, please follow these instructions carefully:
1. Determine Placement
Determine where in the ceiling the speakers will be placed using the recommendations under SPEAKER PLACEMENT. Pay careful attention to the section on avoiding obstructions.
2. Mount InstaLLock Bracket
For best results, mount the SpeakerCraft InstaLLock New Construction Brackets for the AccuFit CRS7 Series
(Part No. BKT90611) following the instructions included with the bracket.
3. The Location is Ready for Drywall
The bracket provides a stable opening around which the drywall installer can cut out an opening, providing a perfect
location for installation of the AccuFit CRS7 Series speaker.
When the speakers will be installed into a finished ceiling, please follow these instructions carefully:
1. Determine Placement
Determine where in the ceiling the speakers will be placed using the recommendations under SPEAKER PLACEMENT. Pay careful attention to the section on avoiding obstructions.
2. Locate Obstructions
Find the joists nearest the desired speaker mounting location. The use of a good stud-finder tool is highly recommended
for this procedure. Make sure that there are no joists or obstructions where you plan to install the speaker. Read “Checking
for Obstructions” under the section SPEAKER PLACEMENT.
3. Trace Template
Place the cut-out template at the location you have decided to place the speaker. Use a few pieces of tape or small
tacks to hold the template in place. Trace an outline on the ceiling with a pencil.
4. Cut the Hole
CAUTION: This is the most important part of the entire installation. If you are not certain whether or not an obstruction exists
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 45˚ angle towards the inside of the hole (See 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 are no obstructions in your desired mounting location, start cutting the finished hole at a 90˚ angle to
the ceiling surface.

The unique integral four foot mounting system incorporated into each speaker
allows for quick installation following these easy steps:
Figure 4
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.
CAUTION: Over tightening may warp the baffle, crack the ceiling, cause the flange to distort, and make the grille difficult to install.
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.
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).
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
