The Ceiling Series speakers come from the factory with the
tweeter facing straight out from the baffle. This will result in the
overall smoothest response. However, depending on your par
-
ticular primary listening 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. (See Diagram 2)
CAUTION: Avoid
touching metal dome tweeters, as damage may occur
(C640 and C800)
.
Tweeter Adjustment (C640 & C800)
:
The switch labeled TREBLE allows for 3dB of treble adjust
-
ment. Your speakers were shipped with the treble switch in
the “-” position, providing the most linear frequency response.
If you desire more treble, move the switch to the “+” position,
and the tweeter will play 3dB higher. To return to the neutral
setting, push the switch back to the “-” position. (See Diagram 3)
Woofer Adjustment (C640 & C800)
:
The switch labeled BASS allows for 3dB of bass adjustment.
Your speakers were shipped with the bass set to “-”. This
setting provides the flattest bass frequency response. If you
desire more bass, push the switch to the “+” position and the
bass will play 3dB higher. To return to the neutral setting, push
the switch back to the “-” position. (See Diagram 3)
The unique integral four-foot mounting system incorporated
into each Ceiling Series 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, + to + and - 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’s sur
-
face. 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 (See Diagram 4), thereby 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.
4. Push the
grille firmly
into the
slot in the
speaker
baffle.

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” above.
If it is necessary to paint the speakers when they are in
the ceiling, the paint masks provided in the carton must be
installed between the grille and flange while they are being
painted with the ceiling.
Before painting your speakers, remove the material under
the grilles. Once the speakers have been painted, return the
material back into place.
Great care should be taken not to clog the holes of the grille,
as this will reduce the sound quality of the speakers.
Proficient Audio Systems recommends only light spray painting
using 5 parts thinning agent to 1 part paint.
