M2 Master Reference Monitor
Addressing the growing need for high dynamic range and reference-monitor accuracy in a broad range of studios, JBL has developed the M2 Master Reference Monitor: A Free-Standing, 2-Way System that can be placed in any environment to provide an exceptionally accurate monitoring experience. Leveraging a new generation of JBL high-output, ultra-low distortion transducers, the M2 provides in-room frequency response of 20 Hz to 40 kHz, and an extraordinary 123 dB maximum SPL to meet the demanding music, cinema and broadcast production requirements for impactful dynamic range.

TECHNOLOGY


D2 DUAL DIAPHRAGM DUAL VOICE COIL COMPRESSION DRIVER
The Ultimate High Frequency Driver for Critical Reference Monitoring, Extended HF Reproduction, Smooth Response, High Power Handling Measurably Lower Distortion, Reduced Power Compression, Increased Dynamic Headroom

DIFFERENTIAL DRIVE® TECHNNOLOGY
Enhanced Performance and Exceptional Low Frequency Extension, High Output, Very Low Power Compression, Very Low Distortion
Achieving extended, rich low frequency performance within the M2 system design parameters required additional JBL engineering innovations, and the 2216Nd in the M2 is no “off-the-shelf” woofer. It employs no less than five patented technologies to allow bass extension to the limits of the audible range, and high output, free of power compression that is detrimental to a system’s low frequency performance. Echoing the “dual driver” design of the D2, the 2216Nd utilizes dual neodymium magnets and two voice coils. To ensure the ultimate performance, even the use of special wire in the 2216 voice coils is a JBL patented application.

IMAGE CONTROL WAVEGUIDE
Impressive Imaging and Sound Stage, Exceptional High Frequency Detail, Uniform Directivity for Smooth In-Room Response
To support an imperceptible transition between the two drivers, and deliver exceptional imaging, JBL engineers pioneered a new patent-pending waveguide design that enables neutral frequency response, not just on-axis, but off-axis in the vertical and horizontal planes, all the way down to the M2’s 800 Hz crossover point.

LSR LINEAR SPATIAL REFERENCE DESIGN
We all know that many loudspeakers have similar measurements but sound different. By going beyond simple on-axis frequency response measurements, JBL defines the ultimate performance specification for new systems – what it will sound like in your room. At the mix position, you hear a combination of direct sound and sound reflected from the rooms surfaces. For sound arriving at the mix position to be smooth and neutral, it is not enough for a speaker to measure “flat” on-axis; it is essential the speaker have excellent off-axis performance.

M2 ENCLOSURE
Small Footprint, Extended Bass Performance, Patented Low Frequency Port Design
Extended low frequency performance and high SPL can be the formula for unwanted resonance. The M2 enclosure is constructed of rigid 1" MDF and with the aid of JBL’s interferometer, extensively braced for rock-solid stability at the system’s full rated power. The enclosure incorporates a JBL patented Slipstream port design with internal flares that ensure low frequency efficiency while eliminating noise caused by port turbulence. Architecturally elegant, the M2 enclosure occupies a relatively small footprint, and can be transported to various working environments.


SYSTEM INTEGRATION


System Integration
While offering exceptional accuracy “out of the box,” the power of the M2 is fully realized with its intelligent in-room tuning and integration capabilities, ensuring optimum performance in your listening environment.

Orchestral Film Score Recording Returns to New York City with Monitor System from JBL Professional by HARMAN

by JBL Professional | Apr 28, 2016
Audiosmith Digital Solutions and The DiMenna Center rely on JBL by HARMAN’s M2 and 7 Series Master Reference Monitors for optimal recordings

-Press Release PDF-

NEW YORK—New York City’s only orchestral recording studio acoustically optimized for classical music, The DiMenna Center for Classical Music recently installed a complete JBL by HARMAN 5.1 monitoring system consisting of JBL’s M2 and 7 Series Master Reference monitors. The system has already been used for a wide variety of audio recordings, including major film scores, like the recent Coen Brothers release, “Hail, Caesar!”

Leveraging The DiMenna Center’s superb hall acoustically optimized for orchestral performances, recording and mixing experts Audiosmith Digital Solutions partnered with the center to offer full-service orchestral recording capabilities. When Audiosmith’s founding partner Lawrence Manchester needed a studio monitoring system capable of producing accurate and consistent results across any production, he turned to JBL. Manchester is a GRAMMY Award-winning music producer/mixer/engineer with an impressive list of credits, including more than 85 films, such as Martin Scorsese’s Academy Award-winning “The Departed,” musical TV productions, such as “Adele Live in New York City,” and he is also the music mixer/producer for NBC’s “The Tonight Show Starring Jimmy Fallon.”

According to Manchester, who first heard the earlier JBL studio monitors at GRAMMY Award-winning producer Frank Filipetti’s studio in 2006, JBL’s new patent-pending Image Control Waveguide technology is the standout feature on both the M2 and the LSR708i. “When I first heard Frank demo the M2s, I was blown away by the imaging and the bass response, and I could not wait to try them for myself,” Manchester said. “I knew when we started this recording partnership with The DiMenna Center the M2s would be a key component and the LSR708i model proved to be an exciting new loudspeaker that we loved from the start. The Waveguide is a fantastic piece of technology that provides an incredibly engaging and satisfying listening experience.”

As the acoustic interface for the M2’s D2430K and 2216ND transducers, JBL Waveguide technology provides exceptional high-frequency detail and natural balance at nearly any listening position. The technology also ensures detailed imaging and a coherent transition between channels, surrounds and immersive format overhead loudspeakers.

“Consistency in how your mixes translate to the outside world is what makes a good loudspeaker and exciting people when they hear their own music playing back is what makes it a great one,” Manchester said. “With film score production, one needs to be able to hear exactly what’s being recorded in the room and the M2s and the LSR708i monitors provide a unique level of accuracy and reliability.”

The orchestral recording studio’s 5.1 monitoring system features three M2 Master Reference monitors (Left, Center, Right), two LSR708i Master Reference Monitors for surround and a JBL S2S-EX Subwoofer. The system is powered by three Crown I-Tech 5000HD power amplifiers, one Crown DCi 2|300N network amplifier and one Crown DCi 2|1250N network amplifier. The studio also uses the LSR708i in a stereo setup when a near-field listening experience is needed.

Implementing system components that easily integrate was a key motivator behind Audiosmith’s decision to use JBL and Crown solutions. “We rely heavily on networked audio throughout our studio design,” Manchester said. “Having a centrally managed system of DSP components that are designed to work together improves the flexibility of our setup and the accuracy of our listening.”
