Since the working load limits vary with the loading angle, two
important restrictions exist. The angle, with respect to the
vertical axis, of the slings that link the structure that supports
the cluster to the first rows of speakers should not be larger
than 10º as viewed from the front, nor larger than 45º as
viewed from the side. This is important, as heavy tightening of
the tilting strap may result in exceeding the 45º.
