SR1530 3-Way Active Sound Reinforcement Speaker System
 The SR1530 is a high-output, horn-loaded, 3-
way, wide dispersion, active sound reinforcement
speaker system. The combination of active on-board
electronics and high-precision transducers allows the

SR1530
SR1530 to generate high output levels with complete
clarity and high resolution.
 The transducers developed for the SR1530 fea-
ture several innovations specifically designed for
this speaker system. The SR1530 is the first speaker
in its class to feature a horn-loaded mid-frequency
transducer. By designing a one piece 90° x 40° horn,
which includes both the mid and high-frequency sec-
tions, the SR1530 takes advantage of several perfor-
mance benefits. First the 6-inch mid-range’s basket

LF driver shall be mounted in a vented combination of

multi-ply wood and high-pressure injected wood enclo-
sure tuned for optimum low-frequency response. The MF
and HF transducers shall be loaded on a one piece, com-
bination HF/MF horn assembly with optimized wavefront
characteristics. The system shall have a nominal cover- MAIN INPUT
