Suspended Installation
CAUTION
• The strength of the suspension points on the speaker is
per point (maximum).
• Before doing any installation or construction work, consult with an
installation expert.
• When choosing the installation location, suspension wire and
mounting hardware, make sure all are strong enough to support
the weight of the speaker.
• Some fittings may deteriorate over extended periods of time due
to wear and or corrosion. For optimum safety, the installation
should be checked thoroughly at regular intervals.
Yamaha cannot be held responsible for damage or injury
caused by insufficient strength of the support structure
or improper installation.
■ Using eye bolts for suspension
For optimum safety, make sure to carefully follow the
precautions below.
CAUTION
• Use only the supplied eye bolts.
• Use three or more eye bolts for suspended installations.
• Use the optional array frame if you intend to suspend a speaker
from another suspended speaker.
• Install the eye bolts to multiple surfaces of the speaker, not just
one surface.

■ Eye bolt strength
Keep in mind that the strength of the eye bolt differs
depending on the suspension angle of the speaker. Make
sure that the load for each eye bolt is less than 740 kg when
suspending at an angle of 0 degrees, and less than 185 kg
at an angle of 45 degrees.
CAUTION
When using the eye bolts,
make sure that the suspension
angle is within the range of 0
to 45 degrees, as shown
below.
CAUTION
Do not suspend the eye bolts as shown
in the diagram below.
Rotatable horn
NOTE
The horn directivity of the speaker is set at the factory so
that the upward spread is narrow and the downward
spread is wide.
1.
Remove all fixing screws on the grille, and remove the
grille from the speaker.
2.
Remove all screws installed on the horn, pull out the horn
from the speaker, rotate the horn 90 degrees, and
re-install the horn to the speaker.
CAUTION
Be careful when rotating the horn so that you do not accidentally cut
the connection wires connected to the horn driver.
