The external hardware must be designed to be
placed as close as possible to the loudspeaker. It
is strictly forbidden to use rigging hardware that is
at any distance from the loudspeaker at the rigging
points. Tightening the screw with hardware that is
not in contact with the enclosure may result in dam-
age to the rigging points or to the cabinet if excessive
torque is applied.
The connection of the external hardware to the
rigging points must be made using proper bolts (the
usual class is 8.8), following the above prescriptions
and applying a controlled torque value with the help
of a
torque wrench
(dynamometric key).
The tightening torque defines the axial force be
-
tween the bolt and the insert and depends on the
frictions with the washer and the thread of the insert.
As a result of this, in order to apply the same axial
force, smaller torque is required if the parts are lu-
bricated.
The torque to apply has been defined considering
the resistance of the insert, of the wood and the in-
teraction between the parts.
The maximum tighten-
ing torque is 15 Nm for lubricated parts.
Tightening the bolts with higher or not controlled
torque might result in damages and risk for the
safety.
