ACLCR6C
6.5” Ceiling LCR Cinema Speaker
Congratulations on your purchase of the AudioSource
AC Ceiling LCR Cinema Speaker. This product is
designed to reproduce the audio portion of your home
entertainment environment with accuracy and detail
that will satisfy the most discriminating listener.
Please read this Installation Manual to ensure the
pr oper in stallat i on and perform ance of your
ACLCR6C speaker.
Preparing for your Installation
Gather the necessary tools for your installation.
You will need the following tools:
1) A Keyhole or Drywall Saw
2) A Phillips Screwdriver
3) Masking Tape
4) A Pencil
5) A Tape Measure
6) A Stud Finder (recommended)
7) Your AC Series speakers
Placement
Plan your speaker placement carefully. Make certain
that electrical, plumbing and any other services will
not interfere within the ceiling where you plan to install
your speakers. The speakers should be located so
that they provide even coverage at your listening
position. The distance between the speakers should
not be greater than the distance from the speakers
to the listening position (See Figure 1). If the room’s
dimensions or furniture placement prevent adhering
to this requirement, the tweeters in the ACLCR6C
speakers can be swiveled to aim them at the desired
listening position.
New Construction
If you are installing your speakers in new construction
before the finished walls go up, AudioSource offers
New Construction Brackets, which provide a stable
frame that can be fastened to the wall studs or ceiling
joists on 16” or 24” centers. This allows the sheet
rock or other surface covering to be installed and
pro v i d es a template t o c ut the opening f o r the
ACLCR6C speakers.
ACLCR6C Design
The ACLCR6C speakers are specifically designed to
be mounted in the ceiling as front channel Left, Center,
and Right home theater speakers (Figure 1). The
ACLCR6C can also be installed for Rear channel
sound where conventional in-wall or floor speakers
cannot be used (Figure 2). The ACLCR6C can also
be used as a single center channel speaker, or in
conventional stereo pairs.
TV
Existing Construction
In most modern buildings ceiling joists are positioned
on 16” centers, providing a space between the joists of
approximately 14 3/8”. The ACLCR6C requires a hole
diameter of 8-1/8” (206mm). Additionally, you should
allow an extra 1” in all directions behind the ceiling
surface to allow room for the screw clamps that mount
the speaker to the ceiling to swing into position.
Use a stud finder to locate the joists behind the ceiling
surface. Also, you should now check for obstructions
like cross bracing in front of and behind the desired
speaker location.
Figure 2Figure 1
After selecting the mounting location, mark the hole to
be cut out. A template is provided in the speaker box.
Locate and align the template, then mark with pencil on
the ceiling surface. If you are unsure whether there are
obstructions behind the ceiling surface where the
speakers are to be mounted, cut a small hole in the
center of your marked mounting location. Holding your
drywall saw at a 45 degree angle (See Figure 3), cut a
square hole that you can use to locate any obstructions,
should they exist.

Figure 3
The 45 degree wedge shape of the removed surfacing
material will make replacement, if necessary, a much
easier task and yield a better finish when patching the
work.
Once it has been determined that there are no obstructions, cut the hole to mount the speaker using the drywall
saw at a 90 degree angle to the ceiling surface. Cover
the raw edges of the wallboard with masking tape
(See Figure 4). This will prevent the back pressure of the
speaker from blowing loose gypsum dust out and onto
the painted ceiling surface after installation. Do not allow
the tape to extend more than 1/4” beyond the edge of the
hole into the room. The frame of the speaker will cover
and hide the tape.
Grill Removal for Installation
CAUTION! The grill is held in place by contact pressure
around the edges where it attaches to the speaker frame.
To avoid difficulty reinstalling the grill, care should be
taken to not distort its shape while removing it.
While looking at the rear of the speaker assembly, rotate
two of the adjacent mounting clamps outward and then
evenly press them towards the grill. The clamp screws
contact the inner surface of the grill, pushing it gently
out of its mounting groove (Figure 5). Only lift the grill
1/4" (6mm) at this location. Next use the other mounting
clamps to further loosen the grill. Use care to not distort
the grill shape.

Next run your speaker wire to your speaker locations.
UL rated CL3 speaker wire is recommended when
running wire inside your walls. In many areas it may
be required by code. When running your speaker wire
you should avoid having the speaker wire run parallel
to the 120V power lines to avert picking up hum and
interference from the power service. If the speaker
wire needs to cross a 120V power line at a right angle
this is acceptable and will not create a problem.
If you are uncomfortable with running the speaker wire
yourself in existing construction, it is recommended that
you retain a qualified custom home installation specialist
or electrician.
Installing the Speakers
Installation Tip! To further enhance the performance of
your ACLCR6C speaker, the ceiling joist cavity where
you plan to place your speakers can be stuffed with a
generous quantity of fiberglass insulation. Stuff the area
in front of and behind the speaker opening with 6” thick
insulation to a depth of approximately 2 feet beginning
1 foot in front and 1 foot behind the speaker opening. If
the insulation is foil or paper backed, face the backing
away from the ACLCR6C speaker. The addition of this
insulation will help prevent unwanted transfer of sound
into the otherwise large and resonant cavity of the uninsulated ceiling.
Figure 5
It is now time to connect the speaker wire to the speaker.
Your speaker wire is usually coded to identify each
conductor as either positive or negative. This can be by
color coding, or one conductor may have a printed
marking or at least a rib along one edge that you will not
find on the other. Identify which type of polarity coding
that your wire is using. You must carefully observe that
the positive terminal of the speaker output on your
amplifier is connected to the positive terminal of the
ACLCR6C speaker. Likewise, the negative terminal of the
amplifier’s speaker output should be connected to the
negative terminal of the ACLCR6C speaker (Figure 6).

Next make sure that the clamps are positioned inside
frame of the speaker.

With the grill removed, place the speaker in the ceiling
opening. Make sure that the speaker wire is not hanging
against the speaker where it can vibrate and rattle as the
speaker reproduces your audio program.
Painting the Speaker
A pain t shield i s incl u d ed in e a ch ACL C R 6C
speaker package. Place the paint shield inside the
frame to protect the speaker. You can now safely
paint the speaker frame to match your wall surface
if you desire.
When painting the grill caution should be taken to
ensure that pai nt does n ot clog o r congest the
perforated openings in the grill. This would prevent
proper operation of the grill by restricting the airflow
from the individual drivers in the speaker.
Removing the ACLCR6C Speaker
Installation Tip! Note that the speaker is set in the frame
at an angle so that the cone can be directed toward
the listening position. Ensure the cone of the speaker is
angled toward the listening position before proceeding
to the next step. This is easily done by rotating the
speaker until the optimum angle is achieved, typically
a direct line of sight to

each of the four screws
that operate the clamps
counter clockwise a few
turns until you feel the
clamp is loose from its
resting position. Now turn
the screw clockwise until
you feel the clamp contact
the ceiling surface.

Tighten all four of the mounting screws in the same
manner until the speaker is properly aligned and held
tight to the ceiling surface.
Caution: Do not over tighten!

Should it ever become necessary to remove the
ACLCR6C speaker from the ceiling, simply remove the
grill and turn the four mounting screws counterclockwise until you feel the clamps lock out of position
in their resting flange. The speaker should easily come
out of the wall for service or replacement.

Grill Removal (if installed)
Locate a small hook tool
(available at most auto parts
stores or home improvement
shops, resembling a dentist’s
pick- a bent paper clip or
stiff wire will work as well),
hook the metal mesh of the

grill near a corner or edge
and gently pull it towards you.
Only lift the grill 1/4" (6mm) at
this location. Move the tool
1-2" (25-50mm) and repeat
until the grill can be removed

Recommended Speaker Wire Gauges
The resistance of the speaker wire in your installation
can cause your speakers to perform at less than their
optimum quality level. Excess resistance caused by
using undersized speaker wire can result in loss of
detail and definition in the bass region of your audio
program as well as loss of dynamic range. Over
extremely long wire runs you may even experience a
loss of high frequency content in the audio signal.
Using gentle pressure, swivel the tweeter to aim the axis
of the tweeter toward the listening area. You can use a
piece of music with a solid center-imaged vocalist to
assist in correctly aiming the tweeter. When the tweeters
are properly aligned, you will hear a coherent and stable
center image from your listening position.
To prevent sonic degradation in your ACLCR6C
speaker installation, total speaker wire resistance
should be kept below 0.5 ohms. The following table
lists recommended speaker wire gauge versus wire
run length.
