LSR6332 Studio Monitor System

The LSR6332 Linear Spatial Reference Studio Monitor combines JBL's latest in transducer and technology with recent breakthroughs in system design to provide a more accurate studio reference in a variety of pro- duction environments.

The neodymium 12" woofer is based on JBL's patented Neodymium Differential Drive NDD™ technology. With the Neodymium magnet structure and dual drive coils, power compression is kept to a minimum to reduce spectral shift as power levels 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 carbon fiber composite forming a rigid piston supported by a soft butyl rubber surround.

The midrange is a 2" neodymium magnet structure with a woven 5" Kevlar cone. The powerful

motor structure was chosen to support the low crossover point to the woofer. In order to achieve the goal of accurate spatial response, the crossover points are located at 250 Hz and 2.2 kHz. These transition points were chosen to match the directivity characteristics of the three transducers.

The high frequency device is a 1" composite diaphragm integrated with an Elliptical Oblate Spheroidal (EOS) Waveguide with 100° by 60° dispersion, which is critical to the smooth spatial response required in today's working environments. The mid and high frequency drivers are mounted within millimeters of each other on a cast aluminum sub-baffle that can be rotated for horizontal or vertical place- ment. This allows maximum flexibility in placement to reduce console and ceiling splash that interferes with imaging and depth.

The 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 compen- sation are implemented in the crossover network. The crossover network allows the user to adjust the high frequency level above 3 kHz. This allows the listener to compensate for effects of near-field or mid-field spectral balance or differing amounts of high frequency absorption. Components used in the crossover are exclusively low-loss metal film capacitors; low distortion electrolytic capacitors; high- Q, high saturation current inductors and high current sand cast power resistors. The mid and high frequency transducers are magneti- cally shielded to reduce interference when used in close proximity to CRT video and computer monitors.

Audio Connections

The LSR6332 is equipped with two pairs of 5-way binding posts. The lower pair feeds the woofer and the top pair feeds the mid and high frequency elements. The connectors are designed to accept up to 10 AWG bare wire. Spacing of the two input terminal pairs allows use of standard Dual Banana jacks. The two pairs are normally connected together with metal shorting bars. This allows either pair to be used in normal operation. Alternative cabling possibilities include passive bi-amping, or using both terminals to get more "copper" from the amplifier to the speaker. Positive voltage to the "Red" (+) terminal will produce a forward motion at the low frequency cone.

High Frequency Adjustments

The LSR6332 High Frequency level can be adjusted to compensate for placement or for "bright" rooms. The unit is shipped in the "flat" or 0 dB position. If the system sounds too bright in your room, or if you are working very close to the monitors (under 1-1.5 meters). the response above 2 kHz can be reduced by approximately 1 dB, as shown in Figure H:

LSR6300 specifications

The JBL LSR6300 series of studio monitors is renowned for its exceptional sound quality and precision, making it a preferred choice for both professional studios and passionate audiophiles. With advanced technologies and meticulous engineering, the LSR6300 series delivers a clear, accurate listening experience that is vital for mixing and mastering.

One of the standout features of the JBL LSR6300 is its Image Control Waveguide technology. This innovation ensures not only a wide sweet spot but also excellent off-axis performance. This means that no matter where you are positioned in relation to the speakers, you'll receive a balanced and consistent sound. This technology allows for an even distribution of sound across the audio spectrum, making it easier for engineers to make informed decisions about their mixes.

In terms of drivers, the LSR6300 series boasts high-performance woofers and tweeters that are specifically designed to provide an extended frequency response. The 8-inch woofers replicate low frequencies with impressive depth, while the 1-inch neodymium tweeters deliver crisp high frequencies without introducing distortion. The result is a full-range output that captures the nuances of any audio material.

Another notable characteristic is the room tuning controls on the back of the monitor. These controls enable users to optimize the sound output based on the acoustic environment of their studio. By adjusting the low-frequency and high-frequency settings, you can compensate for any acoustic anomalies in the room, ensuring your mixes translate well to other playback systems.

Furthermore, the LSR6300 is equipped with JBL's patented Slip Stream port design. This rear-firing port minimizes turbulence and enhances low-frequency response. The design ensures that bass notes are rendered with clarity and punch, allowing for a dynamic listening experience without excessive boominess.

The robustness of the LSR6300’s construction is also noteworthy. With a solid enclosure that reduces resonance, the monitors are built to withstand the rigors of daily use. The sleek, professional appearance adds to their appeal in any studio setting.

In conclusion, the JBL LSR6300 series integrates advanced technologies and thoughtful design elements, making it an exceptional tool for audio professionals. With its accurate sound reproduction, flexible room control options, and thoughtful engineering, the LSR6300 continues to set a high standard in the field of studio monitoring.
