FEATURES

• Heavy-Duty Loudspeaker with Optimum Voice and Signal Intelligibility

for Industrial, Marine, Military and Vehicular Applications

• Impact and Environment-Resistant Construction for Dependable

Indoor/Outdoor Use

• U.S.-Made Compression Driver Assures High Reliability

• Specifically Designed for Surface or Concealed Mounting

APPLICATIONS

Utilize loudspeaker Model MO-2 for signal transmission in inter-
com/talkback, electro-acoustic warning, CB, transceiver and public ad-
dress systems in marine, vehicular, military, service and processing fa-
cilities. Unit is ideal for concealed mounting or where minimum aero-
dynamic obstruction is desired. Model MO-2 is engineered to with-
stand demanding environmental elements as produced in mining,
steel and chemical processing, oil exploration, power generation and
railroad facilities. Note: for explosion-proof loudspeakers refer to
HLE/MLE Series, SL2-1421.

GENERAL DESCRIPTION

Compact, double re-entrant unit with platform base is constructed of
heavy-gauge, die cast aluminum to minimize potential damage caused
by vibration, shock, impact, dust, wide temperature variations, high hu-
midity, salt water and other rigorous conditions. Its integral compres-
sion driver provides optimum efficiency and signal intelligibility. Model
MO-2 also assures superior sensitivity when used as a microphone for
two-way intercommunication. All exposed parts are finished in grey
epoxy. Dimensions: 6
