4.3.2 Suspending the Loudspeaker
A minimum of three suspension points must be used per speaker to safely
suspend the ULT-series full-range loudspeakers. Two wires fixed symmetrically
to the front of the cabinet to hold the weight and one wire attached to the back
for tilt will satisfy this requirement. Select the strongest overhead structure
available for the two front points and, if possible, two independent points to
allow one to act as a backup. Attach the two front points first and then adjust
tilt angle to ensure the load is safely suspended during installation. If additional
pan or height adjustments are needed, make sure to follow this rule as well.
SUPPORTED: Two front rigging points plus a pull-back
Do not suspend any other items from PreSonus ULT-series loudspeakers.
NOT SUPPORTED: One Loudspeaker attached to another
