11.4 Enclosure Finish
The enclosures are finished with a water-based acrylic paint (trade-named Polene™). If desired, this
finish can be painted over with a custom color using any standard, water-based, DTM acrylic paint
without the need for any special surface preparation.
FE models are finished in black, hand-laminated fiberglass. If it is desired to paint these enclosures
with a custom color, they must be sanded and then washed with a solvent (such as turpentine or
denatured alcohol) prior to painting. A spray-on acrylic paint will yield the best results but even then,
results may be unpredictable in terms of the quality, durability and longevity of the new finish.
11.5 Mounting and Rigging
WARNING:
Mounting or rigging loudspeakers is a serious endeavor and requires an experienced
professional. Improper installations may result in damage, injury or death. For this reason, no
loudspeaker should be mounted or suspended overhead unless the method has been approved
by a registered Professional Structural Engineer.
WARNING:
NEVER USE THE HANDLES FOR SUSPENDING THE LOUDSPEAKER. They are neither designed nor
rated for this purpose.
CAUTION:
All fixed hardware used for overhead mounting or suspension should be designed, tested, and
certified for its intended use with a minimum design factor or 5:1. A minimum design factor or
8:1 should be employed for any component which may be subject to continuous wear or
friction, such as moving wire rope. A design factor is the ratio between the structural failure
point and the loading to be applied to the component.
CAUTION:
Routine inspections and maintenance should be performed on any mounting or rigging system.
Any parts found to have deterioration, excessive fatigue, or excessive wear should be removed
from service immediately.
11.5.1 Design Factor for Working Load Limits (WLL)
)
The WLL limits listed for SLS and SBS mounting/rigging points and pull-back points have a design
factor of 20:1.
11.5.2 Mounting/Rigging Points
All SLS and SBS loudspeakers have internal, captive 3/8”-16 threaded nuts for suspending or
permanent mounting. Four are located on the enclosure top and four on the bottom. Each of the 8
mounting/rigging points has a Working Load Limit (WLL rated for 300 lb. (136.1 kg) vertical pull and
75 lb. (34 kg) horizontal pull. Refer to FIGURE 9 for pull directions. Community’s WLL ratings include
a 20:1 safety factor.
