O alto-falante PD743i Precision Directivity™ oferece reforço sonoro de alto impacto em distâncias que ultrapassam o alcance de designs tradicionais de driver único. Um único módulo produz mais de 104 dB SPL (contínuo) a distâncias de 50 m (165 pés). O PD764i-215 pode ser utilizado em clusters com outros módulos da família PD ou individualmente como parte de um sistema distribuído.
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.
