3. INSTALLATION

Unpacking and Inspection

Visually inspect the outside of the shipping carton and check for any damage. After 

unpacking, if you find concealed damage to the loudspeaker, save the packing materials for 

the carrier’s inspection, notify the carrier immediately, and file a shipping damage claim. 

Although EAW Commercial will help in any way possible, it is always the responsibility of 

the receiving party to file any shipping damage claim. The carrier will help prepare and file 

this claim.

Mounting Precautions

The loudspeaker is fitted with threaded 

mounting holes, suitable for attaching user-

supplied forged shoulder eyebolts and flying 

hardware, or an OmniMount 120.0 Series wall-

mount bracket. The details of the mounting 

points are shown in the drawings on page 11.

WARNING:

 Installation should only 

be done by an experienced technician. 

Improper installation may result in 

damage to the equipment, injury or 

death. Make sure that the loudspeaker is installed in a stable and secure way in 

order to avoid any conditions that may be dangerous for persons or structures: 

•  Check to make sure that the support surface (e.g., wall, etc.) has the necessary 

mechanical characteristics to support the weight of the loudspeaker without the 

danger of it falling.

•  Always use support elements suitable for the material of the wall that will support 

the loudspeaker (e.g., screw anchors for bricks, screw anchors for cement, etc.). 

Consult a building professional for the proper mounting hardware. 

•  Before suspending the loudspeaker, carefully check all the components to be used to 

make sure there is no damage, deformation, corrosion and/or missing or damaged 

parts that could reduce the safety of the installation.

 

Consult a professional rigger or structural engineer prior to suspending loudspeakers 

from a structure not intended for that use. Always know the working load limit of the 

structure supporting the loudspeaker. Always make sure that the rigging hardware 

minimum rating is at least five times the actual load.

•  Avoid installing the loudspeaker in places exposed to harsh weather conditions.
