After selection of 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 speaker is 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 Fig. 2) 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 Fig. 3). This will prevent the back pressure of the speaker from blowing loose gypsum dust out and on to 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 AC6CD will cover and hide the tape.

Next you will want to run your speaker wire to your speaker locations. A UL rated CL3 speaker wire is recommended when running wire inside your walls. For proper wire gauge see page four.
When running your speaker wire you should avoid having the speaker wire run parallel to the 110V power lines to avoid picking up hum and interference from the power service. If the speaker wire needs to cross a 110V power line at a right angle this is acceptable and should 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 AC6CD speaker, the ceiling joist cavity where you plan to place your speaker can be stuffed with a generous quantity of fiberglass insulation. If uninsulated, 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 of and 1 foot behind the speaker opening. If the insulation is foil or paper backed, face the backing away from the AC6CD speaker. The addition of this insulation will help to prevent the 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 AC6CD. 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 AC6CD speaker. Likewise, the negative terminal of the amplifier’s speaker output should be connected to the negative terminal of the AC6CD speaker.

Next make sure that the doglegs are positioned inside the 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 music.
Next, one at a time, turn each of the four screws that operate the doglegs counter clockwise a few turns until you feel the dogleg is loose from its resting position. Now turn the screw clockwise until you feel the dogleg
