Community R-Series Installation/Operation Manual for Models R.5 and R.25 — Page 24
Community does offer in its catalog forged, rated eyebolts intended for rigging loudspeakers. However, these
eyebolts are not rated for outdoor use and the shank is too long for the threaded inserts on R.25 and R.5
loudspeakers. Using an eyebolt with too long of a shank will not permit the eyebolt shoulder to properly seat
against the exterior of the cabinet. Installers will need to procure appropriate hardware made from the
appropriate material and shank length to meet the needs of each application.
In some cases, forged, overhead rated shoulder eyebolts may be used as attachment points on the cabinet for
safety cables with some restrictions. The eyebolt must be screwed in and firmly seated (do not over tighten) with
the shoulder of the eyebolt making contact with the rubber washer on the exterior of the cabinet. A rubber
washer shall be used between the eyebolt and the cabinet to maintain weather resistance. Shims may be used
between the eyebolt and the rubber washer to position the eye so that it is in the same plane as the suspension
cable or chain. Care must be taken to ensure that the safety cable will not induce a load off-axis from the
eyebolt’s threaded shank.
Hoist Rings provide a method of attachment which has advantages over eyebolts that permit more flexibility in
regard to the pull/load direction of the safety line, though at a higher cost. Hoist rings include a hinged “eye”
which allows the load applied to the cabinet threaded inserts to remain largely in shear, thus preserving the
integrity of the insert point. The same precautions should be taken to properly seat the hoist ring as when
seating an eye bolt.
As with all aspects of mounting and rigging loudspeakers, the use of eyebolts, hoist rings, and other safety
cabling hardware should be included in a rigging plan approved by a professional engineer.
IMPORTANT: The mounting bolts that come installed in each R-Series enclosure must either be used
to mount the Accessory Mounting Yoke or they must remain in place. If the rigging fittings are not sealed,
air leaks will occur in the enclosure that will compromise the loudspeaker’s weather-resistance and its
low frequency performance.
IMPORTANT: Eyebolts and other mounting hardware for outdoor usage with R-Series loudspeakers
must be corrosion resistant steel properly rated for the load weight.
Custom Mounting Brackets
Custom brackets may be used. When mounting the loudspeaker the bracket should pull directly either in tension
or shear on the mounting point (See Figure 5). It is recommended that any custom bracket be designed to utilize
two mounting points on the opposite sides or top and bottom of the enclosure.
Orienting an R-Series Loudspeaker
An R-Series loudspeaker has a definite top, bottom and sides. However, a 180 degree inversion will not affect
the coverage. When the top of the enclosure is up, the input cable gland nut will be down and to your right when
looking directly at the front of the loudspeaker. Also, the manufacturer's label is on the top of the enclosure.
Once the top is determined, you can properly orient the loudspeaker for your particular application according to
the specified coverage pattern.
