MOUNTING & RIGGING OPTIONS
Rigging Hardware & Accessories
The EMS-121X has a variety of options available for mounting and suspension.
The EMS-121X contains 12 M10 threaded fixing points around the enclosure, to enable suspension using forged
shoulder eyebolts (minimum thread length 25mm) or the optional FC-121v vertical or FC-121h horizontal flying
yokes. These fixings allow suspension in any orientation, with the unused points available for pull-back to obtain
the desired rigging angle or as a secondary safety point.
With any suspension method, a second anchor point should be used as a safety.
Under no circumstances should the mounting points of one enclosure be used to suspend another
enclosure below it. EM Acoustics are in no way responsible for the failure of incorrectly rigged
systems. This information relates specifically to the rigging techniques for the EMS-121X enclosures
only. If you are in any doubt about safe practices for rigging loudspeakers, please contact your local
EM Acoustics dealer who will be able to advise you.
Permanent Installations
Any installation (permanent or temporary) must be securely attached to the structure of the building using chain,
steel wire or web straps that are certified and load rated for the loudspeaker system. Consideration must be taken
when determining the loading on the structure to include loudspeakers and rigging hardware, and the appropriate
safety factor can then be decided upon. If you are in any doubt whatsoever, please contact your EM
Acoustics dealer who will be able to refer you to an experienced rigging company. A reputable rigging organisation
should also be able to advise on legislation regarding safety factors for suspended systems of this type.
Safety Considerations
When utilising any suspension method, a secondary safety must be used. For any suspension method, fit an M10
eyebolt to any of the unused rigging points. A safety steel can then be attached to this and connected to your
safety point. If you are in any doubt whatsoever about how to safely suspend your loudspeakers, do
not hesitate to contact your EM Acoustics representative who will be able to refer you to a qualified
rigging company for advice.
