INSTALLATION
MOUNTING THE BRACKET (IF ATTACHING THE
LOUDSPEAKER TO A WALL, CEILING, BEAM, OR OTHER
SOLID STRUCTURE)
1. Loosen the bracket knobs and remove the bracket from the loudspeaker.
2. Hold the bracket up to the mounting surface horizontally, so that the loudspeaker wire
fits through the large, circular wire hole in the middle of the bracket. Align the bracket
so it is square with the surroundings (use a level for accuracy).
3. Mark the locations of the three oval-shaped screw holes (see Figure 10). Be sure to
use all of the holes.
4. Drill pilot holes into the mounting surface.
5. Pull the loudspeaker wire through the wire hole in the center of the mounting bracket.
Align the bracket so that the holes all line up.
6. Use your hardware to attach the bracket to the mounting surface.
