MOUNTING & RIGGING OPTIONS
Rigging Hardware & Accessories
The MSE-159 and MSE-156 have three options for mounting and suspension, both for temporary use and
permanent fixed installation.
The MSE-159 and MSE-156 are fitted with bespoke flying plates top & bottom of the enclosure to enable
suspension in a variety of ways. Simple suspension is available using M10 forged shoulder eyebolts (minimum
thread length 20mm) in the M10 threaded holes in the flying plates. These M10 points can also be used as
secondary safety points with M10 eyebolts.
The most common method for suspension uses the keyhole cutouts in the top & bottom flying plates. Machined
bosses on the optional flying hardware mate with these keyhole plates, allowing extremely swift attachment of
flying hardware in a touring environment. ¼” ball-lock pins secure the optional flying hardware into the flying
plates.
The MSE-159 and MSE-156 also has an M8 threaded fixing on the rear for use as a pull-back point or for
attachment of 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 MSE-159/MSE-156
enclosure 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.
