Congratulations on your purchase of the AudioSource

AC Dual Mono Ceiling Speaker System. 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

proper installation and performance of your AC

Series speakers.

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 AC6-8CD speaker

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 AC6-8CD speaker can be mounted in

walls, but are typically used in ceilings. The speaker

should be located so that it provides even coverage

at your 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 provides a template to cut the opening for the

AC6CD or AC8CD speaker.

AC6CD/AC8CD

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.

6.5”/8” 2-Way Ceiling Speakers

Existing Construction

In most modern buildings ceiling joists are positioned

on 16” centers, providing a space between the joists of

approximately 14 ”. The specifications chart shows 3/8

the appropriate cut out sizes (p. 4). Additionally, you

should allow an extra ” in all directions behind the 3/4

ceiling surface to allow room for the screw clamps that

mount the speaker to the ceiling to swing into position.

AC Summed Mono Speaker Operation

This AC series speaker is designed for use in areas where

even distribution of sound is desired but stereo imaging

is not practical because of space limitations, such as a

bathroom or long hallway.

With a dual voice coil woofer and dual tweeters, this

AC series speaker can sum stereo amplifier channels

into a mono audio signal. Two pairs of input terminals

allow connection of both channels from a stereo amplifier

to a single summed mono speaker. Set the switch on

the back of the speaker to 16 for summed monoΩ

operation.

Caution! Amplifier damage will occur if the AC6-8CD is

set to 8 with two amplifier channels connected!Ω

AC6-8CD Conventional Speaker Operation

This speaker can be used to reproduce a single channel

of audio by making connection to either set of input

terminals and setting the switch on the back of the

speaker to 8 . In this configuration, both woofer voiceΩ

coils and both tweeters are driven in parallel by the

connected amplifier channel.

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 1), cut a

square hole that you can use to locate any obstructions,

should they exist.

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 obstruc-

tions, 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 2). 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.

Next run your speaker wire to your speaker locations.

A speaker wire is recommended when UL rated CL3

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 Speaker

Installation Tip! To further enhance the performance

of your AC-CD speaker, the ceiling joist cavity where

you plan to place your speaker 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 speaker. The addition of this insulation

will help prevent unwanted transfer of sound into the

otherwise large and resonant cavity of the uninsulated

ceiling.

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

AC-CD speaker. Likewise, the negative terminal of the

amplifier’s speaker output should be connected to the

negative terminal of the AC-CD speaker (Figure 4).

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 3). 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.
