SPEAKER PLACEMENT (ALX2PS / ALX3PS / ALX5.25IC / ALX6.5IC / ALX6.5IC DM / ALX8.0IC)

These speakers are designed to operate in a standard drywall or suspended acoustical panel ceiling.
The speaker enclosure allows for different mounting depths that may be encountered in different ceiling
applications.
Although the speakers sound best when the back section of the speaker is left in tact.
The back section of the speaker can be removed to lessen the over all mounting height if needed.
Some building codes may require that the back enclosure half be removed so please check with your
local building codes.
When mounting to a drywall ceiling, be sure the drywall is at least 3/8” thick.
If you are mounting the speakers to typical acoustical suspended ceiling panels, you will need to
reinforce the acoustical panel with ½” plywood to ensure the speaker does not cause the acoustical
panel to sag over time.

1. Choose mounting locations that are an equal distance left and right of the listening area as shown
in DIAGRAM 1.

2. Use the speaker cut-out template supplied to mark your speaker hole locations.
(Be sure there is clearance behind the area you have chosen for the speaker. Avoid electrical wiring,
plumbing, moving parts, air ducts and Fire Stops.

3. Use a drywall saw or other appropriate tool to carefully cut out the speaker holes. The cut-out is the
exact size required for the speaker. You also can go as much as 1/4” over this size as “Mistake Room”.

4. Connect the speaker wires (18 gauge wire not supplied) to the speakers as shown in DIAGRAM 2.
(Be sure to get the + and - polarity correct)

5. Place the speaker into the speaker opening and using a # 2 phillips screw driver, turn the Dog-Ear
fastening screws clockwise (be sure to support the weight of the speaker until all Doq-Ear screws
are securely tightened).
The Dog-Ear Clamps will rotate away from the speaker enclosure and begin to tighten against the
mounting surface to secure the speaker as shown in DIAGRAM 3.

6. Carefully route the speaker wires to the amplifier or other power source. Be sure to avoid moving parts,
heat producing items and water exposure.
