The MSL-10A Loudspeaker cabinet is
fortified for long-term reliability in outdoor
installations, and is thoroughly inspected at
several stages during assembly. Con-
structed of high-grade Finnish birch
hardwood, the enclosure is resin-impreg-
nated in critical areas, bonded with
structural epoxy adhesive, and coated with
a finish that tolerates cabinet swelling
without cracking. Thermostatically-
controlled environmental heating and
cooling systems, which receive power from
the MSL-10A Rack, ventilate the cabinet
and stabilize its interior temperature.
The MSL-10A cabinet is internally
damped and braced for maximum energy
transfer and highly intelligible reproduc-
tion of voice and music — which is
especially important in acoustically difficult
environments. Internal and external steel
bracing and integral all-steel rigging points
ensure safe, efficient installation, and
integral forklift brackets ease handling.
Component Quality and Linearity
The MSL-10A Loudspeaker employs
driver components whose design, construc-
tion, and testing have been proven in over a
decade of demanding professional use. The
transducer magnetic circuits and suspen-
sions have been optimized for maximum
linearity, resulting in extremely low
harmonic distortion and consistent sonic
accuracy at all dynamic levels. Ferrofluid
cooling and back-vented gaps and pole
pieces maximize power handling, and
water-resistant treatment of all driver
elements ensures greatest reliability in
outdoor installations. Gold-plated contacts
and stainless steel mounting hardware
resist corrosion.
Rigorous Testing
The M-10A Control Electronics and
MSL-10A Loudspeaker components are
individually and fully tested at several
stages of manufacture to ensure maximum
reliability and minimum component
failure.
Each driver is subject to an eight-hour
dynamic burn-in to test for power handling
and peak excursion performance, and
thorough computer-based testing prior to
shipment ensures optimal system operation
upon installation.
Finally, the MSL-10A System has
undergone years of field testing in stadium
installations and touring reinforcement,
resulting in a mature, refined technology
that offers unmatched performance.
