Long-Throw Arrays

To increase the effective throw of

the system, MSL-10A cabinets may be
arrayed one atop another with high
horns together, as shown in the
illustration at the right. Spacer/

hanger bars are used to couple the
cabinets both horizontally and
vertically, as illustrated at the left. A
second set of spacer/hanger bars at
the top provides convenient points for
hoisting and hanging the array.

In this configuration, coupling

between the adjacent horns narrows
the vertical dispersion of the array to

±

10 degrees, moving the focal point

(or virtual source) farther behind the
array. Since inverse-square propaga-
tion losses depend upon the distance
from the focal point (rather than from
the array surface), this configuration
maintains high sound pressures over
very long distances.

The effect is analogous to the

difference between a floodlight and a
searchlight. The floodlight distributes
energy very widely, as though from a
proximate point source, and its
intensity decreases relatively quickly
with increased distance. The search-
light, on the other hand, projects a
narrow, focused beam which is the
equivalent of colimated light from a
distant, very powerful point source.
Its intensity therefore decreases much
more slowly with increased distance.

Ring Configuration

As shown at left, twelve MSL-10A

cabinets arrayed horizontally form a
complete ring providing 360-degree
horizontal coverage.

This system produces prodigious

sound pressures in a reasonably
compact package (80.25" radius), and
is effective for large scale concerts in-
the-round or sporting events in very
large stadiums. Where required,
additional cabinets may be added
vertically, as shown above, to increase
the throw for any portion(s) of the
total arc.
