Before suspending any speaker system always inspect all components (enclosure, rigging frames, pins, etc.) for cracks,
deformations, corrosion, missing, lose or damaged parts that could reduce strength and safety of the array. Do not suspend the
speaker until the proper corrective action has been taken. Use only load- rated hardware when suspending Danley subwoofers.
Are You New to Rigging?
If you are new to rigging, you should do the following:
Know the Rules for Safe Rigging.
Attend a safe rigging seminar, such as that presented by professionals like Rigging Seminars or by Chain Motor Hoist
manufacturers like Columbus McKinnon Corp. (manufacturers of the C/M Lodestar).
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
All Danley subwoofers which are intended to be flown are provided with
⅜
inch - #16 hardware. Any hardware used in an
overhead suspension application must be load rated for the intended use. Generally, this type of hardware is available only from
rigging supply houses; industrial supply catalogs and specialized rigging distributors. Local hardware stores do not usually stock
these products.
Attachment to Structures
A licensed Professional Engineer must approve placement and method of attachment to structures prior to 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, Seismic Code as applicable. Installation of
hardware and method of attachment must be carried out in the manner specified by the Professional Engineer. Improper
installation may result in damage, injury or death.
Rigging Hardware Inspection & Maintenance
Suspension systems are comprised of mechanical devices and, as such, they require regular inspection and routine maintenance
to insure proper function ability. Danley subwoofers must be inspected for fatigue at least annually. The inspection 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 subwoofer enclosure. Accessory rigging hardware provided with or for Danley subwoofers
must be inspected for fatigue at least annually. The inspection shall include a visual material survey for signs of corrosion, bending
or any other condition that may decrease strength of the fastener. For other fittings used, refer to the manufacturer’s inspection
and maintenance guidelines for process.
Danley Sound Labs is not responsible for the application of its products for any purpose or the misuse of this information for any
purpose. Furthermore, Danley Sound Labs 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 flying subwoofer systems should inspect all rigging parts and components.

Operation
4.1
Acoustic Level Warning
Danley Sound Labs subwoofers can produce sound levels capable of causing permanent hearing damage from prolonged
exposure. The higher the sound level, the less exposure needed to cause such damage. Avoid prolonged exposure to the high
sound levels from the subwoofer. Some Tapped Horns are capable of levels in excess of 140 dBSPL! Levels this high can cause
permanent hearing loss! When operating at these high sound pressure levels the user is strongly encourages to use hearing
protection. Danley Sound Labs accepts no liability for hearing damage from using our subwoofers!
