YOKE INSTALLATION
After selecting the speaker location, securely attach the yoke to the surface. An
Adjustable Tilt-Mount Adapter (TMA812) is available to provide various tilt an-
gles. The TMA812 allows attachment to walls and posts.
WARNING: Mounting brackets must be secured in accordance with local
codes. If in doubt, consult a professional contractor to determine the integrity
of the structure to which the bracket will be attached. When required, a safety
cable can be secured to the back of the speaker using the threaded brass insert
on the back of the speaker housing and the forged steel safety bolt (included).
MOUNTING THE SPEAKER ON THE YOKE
The A12 yoke allows the speaker to be
slipped onto it with the locking knobs at-
tached. First, both knobs need to be removed
and the supplied rubber friction disks applied
to the speaker enclosure
where the knobs
clamp. Do not apply the friction disks directly
to the mounting knobs. Next, screw the
knobs back onto the enclosure about two
turns and simply slide the knob shafts down
the slots in the yoke. Now tighten the knobs
making sure that the shoulder of the knob
seats properly through the large hole at the
end of the yoke.
SOME FACTORS TO CONSIDER
Distance is not the only factor affecting sound intensity. Also consider what ad-
jacent surfaces may affect the sound (including but not limited to buildings,
walls, and overhangs). These structures may provide positive effects (low fre-
quency reinforcement) or negative effects (high-frequency reflections that will
degrade intelligibility).
