Next make sure that the clamps are positioned inside frame of the speaker.
Clamp
Frame
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.
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 the listener (Figures 1 and 2).
Painting the Speaker
A paint shield is included in each ACLCR6C 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 paint does not clog or 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
Should it ever become necessary to remove the ACLCR6C speaker from the ceiling, simply remove the grill and turn the four mounting screws counter- clockwise 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.
Next, one at a time, turn 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.

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.
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!
Aiming the Tweeter
Carefully place your fingertips at the plastic edges of the tweeter housing.

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.
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.
50’ or less - 16 Gauge
