Before installing your speakers, you should consider their

placement carefully, taking into account the location of

electrical, plumbing and other ﬁxtures. 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 ideally be located above the primary

listening area. If the speakers are positioned far away from

the primary listening area, 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 high ceilings, it may be necessary to

place additional speakers throughout the room. Contact your

Proﬁcient Audio Systems Dealer for assistance.

New Construction - Unﬁnished 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. If the speakers are to be mounted more Note:

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 neces-

sary 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 electri-

cal 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 loca-

tion. We highly recommend using a good stud-ﬁnder tool

for this procedure. If you are lining up the speakers to some

other object or molding in the room, make sure you con-

sider the size of the bafﬂe ﬂange 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 deter-

mined that there aren’t any obstructions in your desired

mounting location, start cutting the ﬁnished hole at a 90°

angle to the ceiling surface.

5. Add insulation. If the area in the ceiling is not already insu-

lated, 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.

CEILING SERIES

C500 • C600TT • C610 • C620

C640 • C790 • C800

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.
