RIGGING AND MOUNTING WET II ENCLOSURES
One of the most important tasks the installer faces is the rigging and mounting of the loudspeaker system.
WET II loudspeakers have been designed with rigging and mounting in mind; thus, there are numerous ways
to safely and easily install these loudspeakers in optimal locations in a venue.
Safety First!
There is no way to overemphasize the importance of safety. But we’ll try. The kinetic energy of an 80 lb.
loudspeaker enclosure dropping from 30 feet and contacting a concrete floor is enormous. The loudspeaker
will be traveling at a speed of about 35 MPH at the time of impact. Imagine if you were seated under it. You
might have a better chance of surviving a dynamite blast.
If you do not have knowledge of safe rigging practices and experience in applying them, contact a qualified
rigging contractor to design and carry out the installation! Rigging that is improperly installed is like a time
bomb; sooner or later it will fail, with the potential to cause serious injury, paralysis, dismemberment, or
loss of life. Even if no one is directly in the line-of-fall of a failed suspension system, the panic that might
ensue could in itself cause multiple deaths. Do not take chances!
Rigging Guidelines
The following guidelines on rigging are
not
intended as a comprehensive rigging manual, nor are they meant
to replace the knowledge of safe rigging practices that might be obtained from receiving professional
training on the subject. These guidelines are intended
only
to provide basic safety information, and to call
your attention to some commonly made mistakes. Books, seminars, and hands-on courses are available
that teach safe rigging techniques; we highly recommend that you seek them out if you do not already
possess the requisite knowledge and experience to perform rigging work safely.
DISCLAIMER:
Community warrants that its loudspeaker systems and its optional mounting and rigging
hardware have been carefully designed and tested. Community loudspeakers may be safely mounted and
rigged when each loudspeaker model is installed with Community-manufactured optional mounting and
rigging brackets specifically designed for use with that particular model of loudspeaker. This warranty
applies only for use under normal environmental conditions,
3
and when all loudspeakers, component parts,
brackets and hardware are assembled and installed in strict accordance with Community’s installation
guidelines contained herein. Beyond this, Community assumes no further or extended responsibility or
liability, in any way or by any means whatsoever. It is the responsibility of the installer to insure that safe
installation practices are followed, and that such practices are in accordance with any and all local, state,
federal, or other, codes, conditions, and regulations that may apply to, or govern the practice of, rigging,
mounting, and construction work in the relevant geographic territory. Any modifications made to any parts
or materials manufactured or supplied by Community shall immediately void all pledges of warranty or
surety, related in any way to the safe use of those parts and materials.

Load Rated Components
All components of the rigging system such as wire rope, shackles, chain, eyebolts, etc., must be load rated.
This means that they are marked or rated with a
Safe Working Load
(
SWL
) or
Working Load Limit
(
WLL
). All
such items should be designed and manufactured by reputable companies that regularly supply the
theatrical and industrial rigging industries, such as The Crosby Group, or equivalent. It is strongly
recommended that you source your rigging items from an industrial supplier or specialty rigging house,
never from a hardware store. Items found in local hardware stores are often poor copies of the original
designs and may not be safe, as well as typically being more costly than items purchased from an industrial
supplier. By planning ahead, you will not be in the uncomfortable position of having to delay the work if you
can’t locate a shackle or eyebolt at the last minute.

Normal Environmental Conditions are defined as the following: -15 to 55º C, no excessive or unusual air-born contaminants or
pollutants present, no chemicals or contaminants coming in direct contact with the product, no excessive vibration or wind loads.
