1Safety
1.1Suspensions
Warning!
Suspending any object is potentially dangerous and should only be attempted by individuals
who have a thorough knowledge of the techniques and regulations of suspending objects
overhead. Electro-Voice strongly recommends all loudspeakers be suspended taking into
account all current national, federal, state, and local laws and regulations. It is the
responsibility of the installer to ensure all loudspeakers are safely installed in accordance
with all such requirements. When loudspeakers are suspended, Electro-Voice strongly
recommends the system be inspected at least once per year or as laws and regulations
require. If any sign of weakness or damage is detected, remedial action should be taken
immediately. The user is responsible for making sure the wall, ceiling, or structure is capable
of supporting all objects suspended overhead. Any hardware used to suspend a loudspeaker
not associated with Electro-Voice is the responsibility of others.
Caution!
It is the installer's responsibility to determine and use the proper mounting hardware for
the wall construction type.
Disregarding this caution could result in damage to the product and personal injuries may
occur.

4Installation
For safety, ensure the mounting surface supports more than the weight of the speaker. Use
only industry-accepted fasteners and mounting methods when mounting the loudspeaker.
Consult an expert if you are unsure.

It is the installer's responsibility to determine and use the proper mounting hardware for the
wall construction type.
Disregarding this caution could result in damage to the product and personal injuries may
