Cerwin-Vega CVXL-115 Instruction Manual page 16

Use only eye bolts that are professionally certified for the proper 10x load requirements. Suspending loudspeakers is
serious business! Injury or death can occur if loudspeaker systems are not suspended correctly! Read and follow these
instructions carefully! Speaker suspension must take place in accordance with instructions provided by Cerwin-Vega and
under the supervision of a licensed, professional sound/rigging engineer or structural engineer. Only use attachments,
mounts, accessories, or brackets specified by Cerwin-Vega or only specified products rated for overhead suspension. Refer
all servicing to qualified personnel. Servicing is required when the apparatus has been damaged in any way.
SUSPENSION DE-RATING
Using the mounting points at an angle will de-rate the WLL (Working Load Limit) for each mounting point. Each point
mounted at an angle should be de-rated according to the following formula:
CAUTION: When using suspension installation, be sure to observe the following:
 Loudspeaker suspension requires qualified persons who are familiar with rigging standards and practices. Any
unsafe mounting of any heavy load can result in serious injury and equipment damage.
 Consult a licensed, professional engineer regarding equipment installation and ensure that all local, state and
national regulations regarding the safety and operation of loudspeakers and related equipment are understood
and adhered to.
 Do not attempt to suspend the loudspeakers by the handles.
 Before loudspeaker suspension, be sure to inspect all critical points for any cracks, deformations, corrosion
and/or missing parts that may affect the strength and safety of the installation.
 Only use commercially-available M10 load-rated shoulder eyebolts along with rigging hardware appropriate for
the actual load.
 Fittings and rigging hardware may deteriorate over extended periods of time due to wear and/or corrosion, be
sure the installation is checked thoroughly by qualified personal at regular intervals.
 Cerwin-Vega cannot be held responsible for damage or injury caused by insufficient strength of the support
structure or improper installation.
Do not use the pull-back point as the suspension point for a majority of the load. The pull-back points are intended
for angling the loudspeaker downwards only. Note that the loudspeaker suspension points are intended for one
loudspeaker only.

WLL = cosine (angle) x 500
Where:
Angle = degrees from vertical pull
500 = WLL for each CVXL mounting point @ vertical pull
