Introduction

Congratulation on your purchase of LSR6300 Studio Monitors. All LSR6300 models incorporate proprietary and patented JBL transducer and network technologies., to provide ultra-accurate response, and exceptional SPL capability. Because production rooms are acousti- cally less-than-perfect, JBL has incoporated technologies in the LSR6300 Studio Monitors to overcome problems in the room. The result: clear accurate sound at the listening position in any room.

LSR6300 Features to Overcome the Problems in the Room

LSR - Linear Spatial Reference Technology

JBL developed Linear Spatial Reference Technology to improve mid and high frequency accuracy at the listening position where reflect- ed sound comes into play. By meeting frequency response criteria for seventy-two off-axis measurements, the LSR6300 Studio Monitors ensure that not just the direct sound, but the reflected sound that reaches you at the listening position is also smooth and accurate.

RMC™ - Room Mode Correction

The LSR6328P and LSR6312SP Subwoofer are equipped with RMC - JBL’s method of zeroing out bass problems at the listening posi- tion caused by room modes. The LSR6332 Studio Monitor and other speakers enjoy the benefits of RMC when used in a system with the LSR6312SP Subwoofer. The RMC Calibration Kit* gives you everything you need to tune your LSR system and compensate for the room modes in the listening environment.

Boundary Compensation

LSR6328P and LSR6312SP boundary compensation presets restore accurate bass response when the loudspeakers are wall mounted or positioned close to walls, corners and placed on work surfaces.

Mounting Options

LSR6300 enclosures are reinforced to make them safe for mounting and mounting points are provided for use with readily available, industry-standard mounting brackets.

THX® pm3™

All LSR6300 models are THX® pm3™ approved for use in the most demanding production applications and environments.

JBL Transducer Technologies

Differential Drive®

New voice coils and motor assemblies have two separate drive coils with twice the thermal surface area of traditional speakers. This enables LSR6300 systems to provide higher peak output with less power compression, greater heat dissipation and a flatter impedance curve at higher frequencies. By reducing the thermal related effects, the LSR6300 Studio Monitors sound the same at low, medium or high levels.

Linear Dynamics Aperture

Contoured ports virtually eliminate high-end turbulence found in traditional port designs. This provides more accurate low frequency performance at higher output levels.

Dynamic Braking

All LSR6300 low frequency transducers are equipped with an electromagnetic braking voice coil to reduce the effects of extreme excur- sion with high transient program materials.

Titanium Composite High-Frequency Device

Using patented technology, the high frequency device incorporates titanium and composite materials to improve transient response and reduce distortion. By reducing distortion in the lower operating range, where the ear is most sensitive, ear fatigue is radically reduced.

Elliptical Oblate Spheroidal (EOS) Waveguide

Designed for a targeted listening window of ±30º horizontally and ±15º vertically, the EOS waveguide provides a frequency response through the entire window of 1.5 dB from on-axis response. This allows listeners at a distance from the speakers and even far off-axis to hear an accurate representation of the on-axis response.

Neodymium Midrange with Kevlar™ Cone

A 2” neodymium motor structure is used in the LSR6332 for high excursion capability with an intentionally low crossover point of 250 Hz. This improves the spatial response of the system, which is crucial for accurate reproduction.

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.
