MOUNTING & RIGGING OPTIONS
Rigging Hardware & Accessories
The EMS-81 and EMS-121 loudspeakers have a range of integral rigging hardware and optional accessories to
enable usage in a wide variety of ways.
The EMS-81 contains ten M10 threaded fixing points around the enclosure, to enable suspension using forged
shoulder eyebolts (minimum thread length 20mm) or the optional FC-81v vertical or FC-81h horizontal flying
cradles. These fixings allow suspension in any orientation, with the rear point being used for pull-back to obtain
the desired rigging angle. The EMS-81 also includes four M6 threaded fixings on the rear of the enclosure for use
with Omnimount
TM Series 30 or Powerdrive TM Series 75 mounting products.
The EMS-121 contains twelve M10 threaded fixings around the enclosure, to enable similar suspension techniques
as for the EMS-81. The optional FC-121v vertical and FC-121h horizontal flying cradles can also be used for
enclosure suspension. Also included are four M8 threaded fixings on the rear of the enclosure for use with
Omnimount TM Series 60 or Powerdrive TM Series 100 mounting products.
For array assembly, the DFB-81 and DFB-121 dual flybars are available from your EM Acoustics representative.
These steel plates allow two enclosures to be bolted together, with an angle variable from 0 degrees to 40 degrees
splay between the two enclosures.
The EMS-152 has a pair of M10 threaded fixings on the top and bottom of the enclosure for a variety of different
suspension methods, primarily aimed at flexible touring solutions. See the section on page 13 for more details.
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-81 and EMS-121
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.
