The PD743i-215 Precision Directivity™ loudspeaker provides high-impact sound reinforcement at throw distances that are beyond the reach of traditional single-driver designs. A single module produces greater than 104 dB SPL (continuous) at distances of 50 m (165 ft). The PD764i-215 may be used in clusters with other PD family modules or singly as part of a distributed system.
To improve reliability in weather conditions and reduce water ingress, cabinet dimensions of WRC & WRX models may be different than standard model dimensions. Contact CustomAudio@harman.com for drawings and/or dimension information of WRC & WRX models.
