Aiming the Tweeter

easily done by rotating the speaker until the optimum angle is achieved- typically a direct line of sight with the listener (Fig. 8).

Next, one at a time, turn each of the four screws (Fig. 9) 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 contact the ceiling surface.

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

Using your ﬁ ngertips, place them carefully at the edges of the tweeter housing. Apply gentle pressure to swivel the tweeter to aim the axis 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 for the listening area you will hear a coherent and stable center image from your listening position.

Figure 8	Painting the Speaker
	A paint shield is included in the ATCLCR6 speaker package.
	Place the paint shield inside the frame to protect the speaker.
	You can now safely paint the speaker frame to match your
	ceiling surface if you desire.
	When painting the grill caution should be taken to ensure that
	paint does not clog or block the perforated openings in the grill.
	This would prevent full operation from the speaker. We suggest
	spray paint only for this application.

	Removing the ATCLCR6 Speaker
1	Should it ever become necessary to remove the ATCLCR6
	speaker from the ceiling, simply remove the grill and turn the
	four mounting screws counter-clockwise until the doglegs lock
	out of position in their resting seats.

Recommended Speaker Wire Gauges

The resistance of the speaker wire in your installation can cause your speaker to perform at less than an optimum quality level. Excess resistance, caused by using an undersized speaker wire, can result in loss of detail and deﬁ nition in the low frequency region of your audio program, as well as a loss of

dynamic range.

To prevent this effect in your installation, we have recommended speaker wire gauges that should not exceed 0.5 Ohms

resistance over the recommended length of wire run.

For the ATCLCR6 speaker, we suggest the following

minimum speaker wire gauge be used:

50’ or less – 16 Gauge 2-Cond. CL3 (PG model M1650W) 50’ – 100’ – 16 Gauge 2-Cond. CL3 (PG model M16100W)
