JBL PD-743 Brochure
PD743
Very High Output Mid-High
Loudspeaker System
Key Features:
40° by 30° Coverage Pattern –
symmetrical frontal dimensions
allow horizontal or vertical
orientation within an array
IFS™ Interference Free Summation
dual HF driver module eliminates
destructive interference and
increases output by 6 dB
Dual 8" horn loaded cone midfrequency drivers provide 6 dB
greater output than traditional
designs
Pattern control maintained to
below 400 Hz
Co-axial mid/high-frequency
module layout improves midfrequency arrayability and
minimizes size
Integrated rigging system simplifies
array design and construction
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 JBL’s 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.

JBL continually engages in research related to product improvement. Some materials, production methods and design
refinements are introduced into existing products without notice as a routine expression of that philosophy. For this reason, any current JBL product may differ in some respect from its published description, but will always equal or exceed
the original design specifications unless otherwise stated.
