The PD743 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 65 m (215 ft). The PD743 may be used in arrays with other PD series 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. The PD743 transducer complement features JBLs most advanced technology. The 2250J NDD Neodymium Differential Drive® 8" midrange transducer features a high energy neodymium magnet based motor, dual voice coils and a large aluminum heatsink structure. The 2430H compression driver utilizes the latest in magnet and diaphragm technology to pack the performance of a traditional 10.5 kg (23 lb), 25 cm (10 in) diameter compression driver into one weighing 1 kg (2.2 lb) and measuring 10.8 cm (4.25 in) in diameter. For outdoor applications, several levels of weather resistance are available. Please contact your sales representative or JBL for further information.
