Arraying and Rigging
The MSL-10A loudspeaker is
designed to function as a modular
building block capable of being
arrayed in multiples to satisfy a wide
range of acoustical power and
coverage requirements.
Configured as a tightly controlled
30-degree section, the MSL-10A
cabinet features a trapezoidal con-
struction which forms curved arrays.
MSL-10A’s in an array combine
acoustically in a seamless fashion to
form a radiating arc, producing
uniform, coherent wavefronts over
the angle subtended by the array.
The propagation characteristic of
an MSL-10A array thereby closely
approximates that of a theoretically
perfect pulsating gas sphere — but
rather than being omnidirectional,
the radiation is confined to an area
that is controlled by the array con-
figuration. This yields exceptional
intelligibility in reverberant environ-
ments, with substantially the same
sonic character in both the near and
far field – a critical advantage in large-
scale sound reinforcement.
To expedite arraying and installa-
tion, the MSL-10A is fitted with an
integral rigging system. Comprising
steel braces on the cabinet sides and
convenient fork lift feet on top and
bottom, the rigging system eases
handling and provides secure points
from which to suspend the cabinet. In

conjunction with an accessory spacer/

Wide Horizontal Arrays
The minimum MSL-10A configura-
tion is two cabinets (as shown below).
Coupled side-by-side, this configu-
ration delivers 60 degrees horizontal
coverage. Spacer/hanger bars and
case-hardened steel bolts join the
cabinets together and provide rigging
points for hoisting.
To increase the horizontal cover-
age of the array, one or more cabinets
may be added as shown in the
illustration above. Each cabinet added
to the array extends its horizontal
coverage by 30 degrees while main-
taining a consistent 40 degrees of
vertical coverage.
