SPEAKER PLACEMENT

Before installing your 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.

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 pivot-

ing tweeters, read the section entitled “SPEAKER ADJUSTMENTS”
in this manual prior to performing the tweeter adjustment.

Placement In Ceiling: When placing your speakers into the
ceiling, they should ideally be located above the primary
listening area.

MOUNTING SURFACE PREPARATION

New Construction - Unnished 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 bae, which extends beyond the
mounting hole.

3. Mark the hole. A template for setting the hole is provided in
the box. Position the template in the desired position and
pencil an outline on the ceiling.

In a very large room with high ceilings, it may be necessary to
place additional speakers throughout the room. Contact your
Procient Audio Systems Dealer for assistance.

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 of 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.

CAUTION: Speaker components can get hot while playing
music at moderate to high volume levels. There should be
nothing at all touching the speaker. Material in proximity to
the back of the speaker must have at a minimum 1" or 26mm
clearance for non-ammable materials and more for am­mable materials like plastic vapor barriers.

SPEAKER INSTALLATION

The unique integral four-foot mounting system incorporated
into each Ceiling Speaker allows for a quick installation by
following these easy steps:

1. Remove the grille from the speaker baffle.

2. Attach the speaker cable (observing the proper polarity with
your amplier, + to + and – to –). Make sure the left channel
of the amplier is connected to the left speaker, the right
channel is connected to the right speaker, etc.

Tighten the four screws on the front of the bae only

enough to make the speaker 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 speaker.

CAUTION: Over-tightening may warp the bae, crack the

ceiling or cause diculty in aligning the grille.

4. Reattach the grille onto the speaker bae.

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 speaker is designed to ex

and conform to any small imperfections in the ceiling’s surface.

SPEAKER ADJUSTMENTS

The Ceiling Speakers come from the factory with the tweeter
facing straight out from the bae. 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)

NOTE: The tweeters on the C606 do not pivot.

CAUTION: Avoid touching metal dome tweeters, as damage
may occur (C851, C801, C646 & C641).

Tweeter Adjustment (C851, C801, C646 & C641):

The switch labeled TREBLE allows for 3dB of treble adjustment.
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 4)

Woofer Adjustment (C851, C801, C646 & C641):

The switch labeled BASS allows for 3dB of bass adjustment.
Your speakers were shipped with the bass set to “–”. 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. To return to the neutral setting, push the
switch back to the “–” position. (See Diagram 4)

PAINTING THE GRILLES

We recommend painting your grilles prior to installation. If
you decide to paint them in the future, it's best to remove the
grilles by simply detaching them from the speakers. Do not
paint the grilles while they are installed on the speakers.

Before painting, be sure to remove the cloth material from
beneath the grille. Once painted, place the cloth back to its
position beneath the grille.

When painting, be careful not to clog the holes of the grille.
The sound of the speaker will be dramatically reduced if the
perforations in the grille are covered in paint.

Procient recommends only light spray painting using ve
parts thinning agent to one part paint.
