speaker allows for a quick installation by following these easy steps.
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: +
(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 auto-
matically flip into an outward position thereby clamping the drywall between the
feet and the flange. (See 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 environ-
ment. 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.

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.
