INTRODUCTION
Congratulations on purchasing SpeakerCraft’s AccuFit DT7 Series of architectural loudspeakers. The AccuFit DT7 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 DT7 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 application.
SPEAKER PLACEMENT
Before installing your speaker, 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.
Ceiling Placement: When placing your speaker into the ceiling, it should ideally be located above the primary listening area. The
AccuFit DT7 is intended to be used as a single stereo speaker in small listening environments, walk-in closets, laundry rooms, bath
rooms etc. In a large area, it may be necessary to place additional speakers throughout the room to get the optimal effect.
MOUNTING SURFACE PREPARATION
New Construction - Unfinished Ceilings
A New Construction Bracket, SpeakerCraft part number BKT90611 (available from your dealer), may be installed prior to drywall
application across joists (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 speaker can then be easily installed following the instructions
for mounting under “Finished Ceilings” below.
Finished Ceilings
Prior to the actual installation of the speaker, it will be necessary to run cables to the speaker location. See your dealer for more
information on cable installation. After the cable has been properly installed, you are ready to mount the speaker. Following the
simple steps listed below will result in a professional looking installation:
1. Determine the best area to mount your speaker. This area of the ceiling 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 joists nearest the desired speaker mounting location. We highly recommend using a good stud-finder tool for this procedure. If you are lining up the speaker 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.
3. Mark the hole. A punch out template for setting the hole is provided in the box. Position the template in the desired position
and pencil an outline on the ceiling.
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, cutting at a 45º angle towards the inside of the hole. (See Diagram 1) Cutting the small hole at this
angle will make drywall repair much easier, using the piece cut out. Once you have determined that there aren’t any obstructions in your desired mounting location, start cutting the finished hole at a 90º angle to the ceiling’s surface.

SPEAKER INSTALLATION
The unique integral four foot mounting system incorporated into your AccuFit DT7
speaker allows for a quick installation by following these easy steps.
Diagram 2
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: +
(red speaker input) to + and – (black speaker input) to – . Either channel may be
attached to either terminal set, however, be sure that polarity (+ and -) is correct on
each channel or the performance of the speaker will be seriously affected, as one
channel will cancel out the other. (See Diagram 2)
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 four 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 thereby clamping the drywall between the
feet and the flange. (See Diagram 3)
Diagram 3
CAUTION: Over tightening may warp the baffle, crack the ceiling, cause the flange to
distort, and make the grille difficult to install.
4. Push the grille firmly into the slot in the speaker baffle.
ADJUSTING THE FREQUENCY RESPONSE (AccuFit DT7 Three)
The output of the tweeter on the AccuFit DT7 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. Use the chart to determine the result of
the setting you select.
Selecting the Treble Setting on AccuFit DT7 Three
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 Diagram 4).
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
Diagram 4
PAINTING THE SPEAKER
If you plan to paint your speaker, we recommend that it be done prior to installation. If you plan to paint your speaker sometime
in the future, it is best to remove it by simply reversing the steps for “Speaker Installation” listed above. If it is necessary to paint the
speaker while it is still in the ceiling, the paint mask provided in the carton must be installed in place of the grille while the flange
is being painted with the ceiling. The grille 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 speaker. SpeakerCraft recommends only light spray painting using 5 parts thinning
agent to 1 part paint. Do not paint the grille while it is attached to the speaker.
