Attaching the loudspeaker bracket pieces to allow tilting

1.  Select the appropriate attachment location for the bracket on the enclosure 

rear panel. Note that because of the wall or mounting surface, in most cases 
the lowest attachment location offers the widest range of tilt options, while 
the highest offers few, if any, tilt options.

2.  Use two M6×20 screws and their washers to secure the bracket to the 

enclosure. Note that the bracket has four mounting holes; some attachment 
locations use the long-spaced holes and some use the shorter ones.

NOTE: For convenience reasons we recommend configuring the tilt angle 
(Figure 9) before the loudspeaker and bracket are attached to the wall piece. 
However, you can adjust the tilt later, even after the loudspeaker has been 
installed.

Attaching the loudspeaker bracket pieces for no-tilt 

mounting

If the application does not require tilting the loudspeaker, you can either 
configure it for 0 degrees or you can simplify the mounting bracket.
To simplify the mounting bracket, follow these steps
1.  Omit these parts of the bracket kit, shown in Figure 10.
2.  Attach this remaining part of the bracket directly to the loudspeaker enclosure 

(see below left), using the two M6 × 20 screws (Figure 11).

Attaching the loudspeaker to the wall piece

1.  The wall piece has a stud on the top and the loudspeaker bracket piece has a stud on the bottom. 

Set the hole in the loudspeaker bracket piece over the wall piece's stud and guide the loudspeaker 
bracket's stud through the hole in the wall piece (Figure 12).

2.  Set the loudspeaker onto the wall piece.
3.  Install a washer and cap nut on each stud and tighten them finger tight.
4.  Adjust the horizontal pan of the loudspeaker as needed.
5.  If the loudspeaker's desired horizontal angle is perpendicular to the wall, you may install the zero-

pan locking screw to keep it from moving out of position. Make sure that the threaded hole in the 
loudspeaker bracket piece lines up with the hole in the wall piece, then insert and tighten the screw.

6.  Tighten the cap nuts securely.
