e PD743i Precision Directivity™ 2-way mid-high,
horn-loaded loudspeaker provides high-impact sound
reinforcement at throw distances that are beyond the
reach of single-driver designs. A single module produces
greater than 104 dB SPL (continuous) at distances of
50 m (165 ).
e PD743i may be used in clusters with other PD
family modules or singly as part of a distributed system.
e PD743i has the same mid-high features as the
PD743i-215 so they can work seamlessly together.
