JBL LSR 6332
Left and Right Reference Studio Monitor System

The JBL 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 psychoacoustically derived spatial response criteria, resulting in a more accurate studio monitoring reference. In this design process, the system's frequency response over the forward listening range (+/-15vertically and +/-30horizontally) is optimized, as opposed to the conventional approach of optimizing the response directly on-axis. This design approach involves careful component design, selection of crossover frequency, and precise baffle geometry and detail. The result is a system that can be used for the most critical judgements of recording balance, image placement, and equalization.

252G Low Frequency Transducer
The neodymium 12" woofer is based on JBL patented Neodymium Differential Drive NDD technology. With the neodymium structure and dual drive coils, power compression 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.

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.

053TiS High Frequency Transducer
The high frequency transducer has a 1" 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 millimeters 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.

Dividing Network
The impedance compensated crossover filters are optimized to yield 4th-order (24 dB/octave) Linkwitz-Riley electroacoustic responses from each transducer (in-phase, -6 dB at crossover). In order to achieve optimal symmetrical response in the vertical plane, both magnitude and phase compensation are implemented in the dividing network. The network allows the user to attenuate the high frequency level above 3 kHz by 1 dB. This adjusts for spectral balance when used in bright rooms. Components used in the network are exclusively low-loss metal film capacitors, low distortion electrolytic capacitors, high-Q high saturation current inductors and high current sandcast power resistors.
