LCR Ceiling Speakers
C870 • C840 • C660 • C650
SPEAKER PLACEMENT
Before installing your LCR Ceiling Speakers, you should
consider their placement carefully, taking into account the
location of electrical, plumbing and other xtures. Contact
your Dealer for assistance if you are unsure of the best
location for your particular listening environment.
Placement In Ceiling: When placing your speakers into the
ceiling, they should be located so that the xed 15˚ angle
woofer is pointed towards the primary listening area.
If the speakers are positioned far away from the primary
listening area, simply adjust the pivoting tweeters so they are
pointed towards it.
Note: To avoid possible damage to the pivoting tweeters, read the
section entitled “SPEAKER ADJUSTMENTS” in this manual prior to
performing the tweeter adjustment.
In a very large room with low ceilings, it may be necessary to
place additional speakers throughout the room. Contact your
Procient Audio Systems Dealer for assistance.
MOUNTING SURFACE PREPARATION
New Construction - Unnished Ceilings
A Pre-Construction Bracket, available from your Dealer, may
be installed prior to drywall application across joists (up to
24" on-center) where a speaker will be located. After the hole
is cut and the drywall is installed, the speakers are then easily
installed following the instructions for mounting in “Finished
Ceilings” below. Note: If the speakers are to be mounted more
than 24" on-center, a special “Extra Long Wing” is available from
your Dealer.
Finished Ceilings
Prior to the actual installation of the speakers, it will be necessary to run cables to the speaker locations. See your Dealer for
more information about cable installation. After the cable has
been properly installed, you are ready to mount the speakers.
Following the simple steps listed below will result in a professional looking installation:
1. Determine the best area to mount your speakers. 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 xtures 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-nder tool
for this procedure. If you are lining up the speakers to some
other object or molding in the room, make sure you consider the size of the bae ange which extends beyond the
mounting hole.
3. Mark the hole. A template for setting the hole is provided
in the box (along with two paint mask inserts for use when
painting). 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 45°
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 nished hole at a 90° angle to the
ceiling surface.

5. Add insulation. If the area in the ceiling is not already insulated, add an adequate amount insulation material to loosely
cover the back of the speaker. If the insulation material used
is faced with foil or paper, position the foil or paper away
from the speaker.

SPEAKER INSTALLATION
The unique integral four-foot mounting system incorporated
into each LCR Ceiling 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
bae 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 amplier, + to + and – to –). Make sure the left channel
of the amplier is connected to the left speaker, the right
channel is connected to the right speaker, etc.
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 ange of the speaker is designed to ex and conform
to any small imperfections in the ceiling’s surface. Tighten the
four screws on the front of the bae only enough to make the
ange become snug against the ceiling. As you tighten the
screws, the feet will automatically ip into an outward position
(See Diagram 2), thereby clamping the drywall between the feet
and the ange. CAUTION: Over-tightening may warp the
bae, crack the ceiling, cause the ange to distort, and
make the grille dicult to install.
4. Push the grille rmly into the slot in the speaker bae.

SPEAKER ADJUSTMENTS
The LCR Ceiling Speakers come from the factory with the
tweeter facing straight out from the bae. This will result
in the overall smoothest response. However, depending on
your particular primary listening area, room acoustics, ceiling
height, or personal preference, you may nd 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 3) CAUTION:
Avoid touching metal dome tweeters, as damage may occur
(C870 & C660).
Tweeter Adjustment (C870 & C840 Only):
The switch labeled TREBLE allows for ±3dB of treble adjustment. Your speakers were shipped with the treble switch in the
middle 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. If you desire less treble,
move the switch to the “–” position, and the tweeter will play
3dB lower. To return to the neutral setting, push the switch
back to the middle position. (See Diagram 4)
Woofer Adjustment (C870 & C840 Only):
The switch labeled BASS allows for ±3dB of bass adjustment.
Your speakers were shipped with the bass set to the middle
position. This setting provides the attest bass frequency
response. If you desire more bass, push the switch to the “+”
position and the bass will play 3dB higher. If you desire less
bass, push the switch to the “–” position and the bass will play
3dB lower. This setting provides a more linear bass frequency
response. To return to the neutral setting, push the switch back
to the middle position. (See Diagram 4)

PAINTING THE SPEAKERS
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.
Before painting your speakers, install the included paint mask
in place of the grille.
Before painting the grilles, remove the white acoustic
blanket under the grille.

Once the speakers have been painted, return the acoustic
blanket 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.
Procient recommends only light spray painting using 5 parts
thinning agent to 1 part paint.
