Use the appropriate mounting screws. The screw heads must not protrude more than .074" (1.9 mm)
above the screw holes in the mounting plate (see the fi gure below left). If the screw head protrudes too far above the
mounting plate surface, damage to the speaker may occur when the speaker is attached (see the fi gure below right).

location now with the mounting plate positioned on the wall while ensuring that the wall stud does not
interfere with the wire routing and that the mounting plate hides the access hole.
ATTENTION:
Use the appropriate mounting screws (see the above ATTENTION).
Drill the mounting plate pilot holes and cut the speaker wire access hole, as previously marked.
