The PD764 Precision Directivity 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 ft). The PD764 may be used in clusters with other PD family modules or singly as part of a distributed system. PD100 series low-frequency elements may be added to the array to extend bandwidth and pattern control to the lowest octaves.
