High-Density baffle for low enclosure
resonance and stable inertial ground.
Linear Dynamics Aperture port
design eliminates port turbulence
and reduces port compression.
252G Low Frequency Transducer
®
The neodymium 12" woofer is based on JBL patented Differential Drive
technology. With the neodymium structure and dual drive coils, power com-
pression is kept to a minimum to reduce spectral shift as power level increase.
An added third coil between the drive coils acts as a dynamic brake to limit
excess excursion and reduce audible distortion at the highest levels. The cone is
made of a graphite polypropylene composite forming a rigid piston supported
by a soft butyl rubber surround.

Midrange/high frequency sub-baffle
may be rotated by user for horizontal
or vertical orientation.
C500G Midrange Transducer
The 5" midrange transducer has a 2" neodymium magnetic structure with a
woven Kevlar cone. The powerful motor structure was chosen to support the
low crossover frequency to the woofer. In order to achieve the goal of accurate
spatial response the crossover points are placed at 250 Hz and 2.2 kHz. These
transition points match the directivity characteristics of the three transducers.

The LSR6332 studio monitor is
designed for use as a near or mid-field
reference monitor, or a soffit-mounted
main monitor in applications requiring
exceptional spectral accuracy and high
SPL capability. The LSR6332 combines
the latest in JBL’s renowned transducer
and system technology with psychoa-
coustically derived spatial response cri-
teria, resulting in a more accurate stu-
dio monitoring reference. In this design
process, the system’s frequency
053TiS High Frequency Transducer
The high frequency transducer has a composite diaphragm integrated with an
Elliptical Oblate Spheroidal (EOS) waveguide with wide uniform dispersion,
which is critical to the smooth spatial response required in today’s working
environments. The mid and high frequency devices are mounted within mil-
limeters of each other on a cast aluminum sub-baffle that can be rotated for
horizontal or vertical placement, giving maximum flexibility in placement to
reduce console and ceiling splash that interferes with stereo imaging and depth.
response over the forward listening
range ( 15° vertically and 30° hori-
zontally) is optimized, as opposed to
the conventional approach of optimiz-
ing the response directly on-axis. This
design approach involves careful com-
ponent design, selection of crossover
frequency, and precise baffle geometry
and detail. The result is a system that
can be used for the most critical judge-
ments of recording balance, image
placement, and equalization.

JBL continually engages in research related to performance improvements. New mate-
rials, production methods, and design refinements are introduced into existing prod-
ucts 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 specification unless otherwise stated.

Caution: Unsafe mounting or overhead suspension of any heavy load can result in serious injury and
equipment damage. Mounting of speakers should be done by qualified persons in accordance with all
applicable local safety and construction standards. Be certain to follow the instructions provided by
the manufacturer of the mounting bracket. Before selecting a mounting bracket, be certain that it is
capable of supporting the weight of the speaker to be mounted.
