Suspension
The ETX-10P, ETX-12P, ETX-15P, and ETX-35P enclosures have eight (8) M10 threaded points;
six (6) points on top of the enclosure and two (2) points on the bottom. Forged shoulder
eyebolts rated for overhead suspension may be used to suspend an individual loudspeaker,
such as the EBK-M10 accessory.
!
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 regulations. It is the responsibility of the
installer to ensure all loudspeakers are safely installed in accordance with all such
regulations. When loudspeakers are suspended, Electro-Voice strongly recommends the
system be inspected at least once a year. If any sign of weakness or damage is detected,
remedial action should be taken immediately. The user is responsible for making sure the wall
or ceiling is capable of supporting the loudspeaker. Any hardware used to suspend a
loudspeaker not associated with Electro-Voice is the responsibility of others.

Prior to use, inspect the suspension points and associated hardware for any cracks,
deformations, broken welds, corrosion, missing or damaged components which could reduce
the suspension points strength. Replace any damaged hardware. Never exceed the limitations
or maximum recommended load intended for the suspension points. As an added safety
measure, it is suggested the user install an extra suspension point back to the building
structural supports. This redundant safety point should have as little slack as possible (less
than one (1) inch is preferable). Prior to each use, inspect the loudspeaker enclosures for any
cracks, deformations, missing or damaged components, which could reduce enclosure
strength. Replace any loudspeaker systems damaged or missing hardware.
