The JBL LSR6300 and LSR4300 Series go “beyond accurate”all the way to “stunning”by incorporating features which reduce the effect of problems in the room. We start with JBL transducer and network technologies that provide ultra-flat response and exceptional dynamic range. Then we incorporate features that help to overcome the contributions of the room. So even if you work in a small home studio, you’ll have clear sound at the mix position. All LSR models are engineered for use in the most demanding production environments. With JBL’s LSR6300 Series and the new LSR4300 Series, mixing is a pleasure.

It takes more than an accurate speaker system to have accurate response at the mix position. Problems in the room dramatically color what you hear at the mix position. Walls and corners can affect response. And standing waves at the mix position can lead you to misjudge bass content. As a result, a speaker which measures flat in an anechoic chamber may “tell you a different story” in the room. The key to accu- racy is tackling the effect of boundaries, standing waves and reflections. In developing the LSR Series, JBL examined each problem in the environment and created the perfect solu- tion. Even if you work in a small control room, an LSR system will provide smooth accurate response at the mixer’s chair.

RMC™ (Room Mode Co rre ct i o n )

Room modes or standing waves can mislead you give you a false impression of low frequency content in the mix. JBL is first to supply a complete solution for identifying and overcoming the nega- tive effect of room modes. The LSR 6328P, 6312SP and all LSR4300 models are equipped with RMC™, JBL's ingenious Room Mode Correction System. The LSR6300 RMC Calibration kit includes every- thing needed to identify room modes and set the LSR6300 series on-board parametric equalizer. JBL engineers took the RMC solution one step further by equipping the LSR4300 Series speakers with an automated analyzer and corrective filter. Both systems dramatically improve low frequency performance at the mix position.

Built-in Boundary Co m pe n s ation

With the advent of multi-channel production, space limitations may compromise the positioning of the speakers. JBL’s powered LSR6300 models include boundary compensation switches and the LSR4300 RMC Systems includes filters to offset the increase in bass response, that occurs when the speaker is placed near a wall, in a corner or on a work surface.

Stunning Sound

Starting with application-designed and built transducers engineered for extremely accurate response and superb power handling, the stun- ning sound of the LSR Series Studio Monitors make long mix sessions a pleasure.The LSR6300 line* incorporates the single most significant

LSR (Linear Spatial Reference Technology )

Much of what you hear at the mix position is reflected—not direct sound. Linear Spatial Reference Technology ensures mid and high frequency response of our speakers is neutral at the mix position. The exact geometry of the wave- guide, the interaction of the woofer and tweeter, and the network are designed to provide an accu- rate listening window of ± 30 degree horizontal,

±15 degree vertical. As a result, the reflected sound that reaches the mix position

is smooth and accurate.

advance in monitor history: JBL’s patented Differential Drive Technology. Providing unparal- leled performance, the woofer permanently dispels the notion that better linearity, higher power handling and greater dynamic accuracy

are somehow unobtainable. JBL’s Differential Drive uses two drive coils with twice the thermal surface area of traditional speakers. As a result, LSR6300 systems provide higher peak output with less spectral shift that causes monitors to sound different when driven at different power levels. All LSR Series speakers withstand the JBL loudspeaker torture test driven at full rated power for over 100 hours. Meeting higher stan- dards than any other loudspeaker manufacturer,

Di f fe re ntial Drive® Technology

LSR6332

Elliptical Oblate Spheroidal (EOS) Waveguide

Designed for a targeted listening window of ± 30 degrees horizontally and ±15 degrees vertically, the EOS provides smooth response through the entire listening window within 1.5 dB of the on-axis response. The result:The listener, even far off-axis, can hear an accurate representation of the on-axis response.

Composite High Frequency Device

The 1" magnetically shielded dome high frequency device incorporates titanium and composite materials to improve transient response and reduce distortion. The result: By reducing distortion in the lower operating range where the human ear is most sensitive, listener fatigue is dramatically reduced.

500G Midrange Transducer

The midrange is a 2" neodymium motor with a 5-inch woven 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 match the directivity characteristics of the three transducers for optimum spatial response. The result: Absolute pinpoint accuracy.

Dynamic Braking

LSR6300 low frequency transducers are equipped with an electromagnetic braking coil that reduces the effects of extreme excursion with high transient material.This causes more linear compliance resulting in lower distortion, more accurate reproduction and increased reliability.

JBL’s demanding test ensures that the LSR Studio Monitors give you accurate mixes year after year.

Reinforced mounting points on LSR speakers allow convenient positioning and installation of multi-channel surround systems for any mixing application, in any studio environment.

Studio Monitors specifications

JBM electronic Studio Monitors have carved a niche for themselves in the competitive audio monitoring market, especially favored by musicians, producers, and sound engineers. These monitors are engineered to deliver accurate sound reproduction, ensuring that audio professionals can trust the source material they are working with.

One of the main features of JBM Studio Monitors is their impressive frequency response. They typically cover a wide range, often extending from 40 Hz to 20 kHz. This broad spectrum allows for a comprehensive listening experience, revealing nuances in recordings that might be missed with less accurate speakers. Additionally, many models incorporate advanced bass reflex designs, enhancing low-frequency performance without distortion.

The build quality of JBM monitors is another standout characteristic. Constructed from high-density MDF, they minimize resonance and provide a cleaner sound. The enclosure design works in tandem with the speaker's drivers to deliver clarity across different sound levels. The use of professionally tuned port systems ensures that low-end frequencies are reinforced, resulting in a punchy yet balanced bass response.

In terms of technology, JBM Studio Monitors often employ Class A/B amplifiers, which combine the strengths of both Class A and Class B to deliver power and efficiency. This amplification approach is integral to achieving minimal distortion, allowing for precise audio playback. Some models feature bi-amped designs, using separate amplifiers for the woofer and tweeter, further enhancing the monitors' fidelity and dynamic range.

Another notable feature in JBM electronic Studio Monitors is their room adjustment controls. Many units come equipped with equalization settings that allow users to tailor the sound profile to their specific environment, compensating for room acoustics and ensuring optimal playback. This adaptability is crucial in a professional setting where space can vary greatly.

Connectivity options are abundant, often including TRS, XLR, and RCA inputs, making these monitors versatile and compatible with various audio interfaces and mixers. The user-friendly design extends to ease of placement, with some models compact enough to fit in smaller studio setups while still delivering powerful sound.

In summary, JBM electronic Studio Monitors are designed to offer unrivaled sound accuracy and flexibility for audio professionals. With features like a wide frequency range, robust build quality, advanced amplification technology, and useful room tuning options, these monitors stand out as a worthy investment for anyone serious about sound production. Their reputation for reliability and performance makes them a popular choice among those in the audio industry.
