IMPORTANT SAFETY INSTRUCTIONS

The PRX800W Series speakers covered by this manual are not intended for use in high
moisture environments. Moisture can damage the speaker cone and surround and cause
corrosion of electrical contacts and metal parts. Avoid exposing the speakers to direct
moisture. Keep speakers out of extended or intense direct sunlight. The driver suspension

energy. When placed on a slippery surface such as polished wood or linoleum, the
speaker may move due to its acoustical energy output. Precautions should be taken to
assure that the speaker does not fall off a stage or table on which it is placed.
Stand Mounting Safety Precautions
Some PRX800W Series models include a 36 mm receptacle cup to allow mounting on tripod stands or on a pole
over subwoofers. When using stands or poles, be sure to observe the following precautions:

sure to fully extend the legs of tripod type stands. Position the stand so that the legs do not present a
trip hazard.
• Route cables so that performers, production crew, and audience will not trip and topple the speakers over.

Are You New to Rigging?
If you are new to rigging, you should do the following:
• Read and study JBL Technical Note Volume 1, Number 14: Basic Principles for Suspending Loudspeaker
Systems (available at KWWSZZZMEOSURFRPFDWDORJVXSSRUWJHW¿OHDVS["GRFLG GRFW\SH 
• Know the rules for safe rigging.
• Attend a safe rigging seminar, such as that presented by professionals like Rigging Seminars™ or by Chain

• Meet and establish a relationship with a licensed mechanical or structural engineer. Get in the habit of asking
them questions instead of guessing about their answers. Learn from what they tell you.
• Meet and discuss this aspect of your business with your Insurance Agent.
• Research and understand the codes, practices, and requirements in the venues where you intend to operate
your sound system.
General Hardware Information
Any hardware used in an overhead suspension application must be load rated for the intended use. Generally,
this type of hardware is available from rigging supply houses, industrial supply catalogs and specialized rigging
distributors. Local hardware stores do not usually stock these products. Hardware that is intended for overhead
suspension will comply with ASME B30.20 and will be manufactured under product traceability controls.

Attachment to Structures
A licensed Professional Engineer must approve the placement and method of attachment to the structure prior
to the installation of any overhead object. The following performance standards should be provided to the
Professional Engineer for design purposes; Uniform Building Code as applicable, Municipal Building Code
as applicable, and Seismic Code as applicable.

Inspection & Maintenance
Suspension systems are comprised of mechanical devices and, as such, they require regular inspection and
routine maintenance to ensure proper function ability. JBL suspendable loudspeakers must be inspected for

shall include a visual survey of all corners and load bearing surfaces for signs of cracking, water damage,
de-lamination, or any other condition that may decrease the strength of the loudspeaker enclosure. Accessory
suspension hardware provided with or for the JBL loudspeakers must be inspected for fatigue at least annually.
The inspection shall include a visual survey of the material for signs of corrosion, bending or any other condition
that may decrease the strength of the fastener. Additionally, any eyebolts shall be checked for possible spin-out
of the enclosure.

JBL is not responsible for the application of its products for any purpose or the misuse of this information for
any purpose. Furthermore, JBL is not responsible for the abuse of its products caused by avoiding compliance
with inspection and maintenance procedures or any other abuse.
Prior to suspending the system, an expert, trained and experienced in suspending speaker systems should
inspect all rigging parts and components.

maintained with a safety factor of 5:1, provided no more than 470lbs/213kg from 2 points equally loaded, or no
more than 235lbs/106kg maximum from a single suspension point, is utilized in conjunction with industry
recognized safe rigging practices and the guidelines established within this manual.
For permanent installation applications utilizing the M10 suspension points order JBL 229-00009-01.
This kit includes three M10 x 35 mm forged shoulder steel eyebolts with washers.
WARNING
Suspension of JBL loudspeakers must employ a minimum of two attachment points. When “bridling” a JBL
loudspeaker system, two legs of equal length must be used. The rear attachment points are pull-back points and
are intended only for use in adjusting the down-angle of the speaker enclosure. Only the top and bottom
attachment points are intended for use as suspension points.
