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 opt imum safety, make sure to carefully follow the

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.

Remove all fixing screws on the grille, and remove the

grille from the speaker.

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.
