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.

HARMAN’s JBL M2 Master Reference Monitors Prove “Pitch Perfect” for Music Mixer Joseph Magee

by JBL Professional | Apr 10, 2014
Music mixer Joseph Magee, whose impressive credits include Saving Mr. Banks, Pitch Perfect, High Fidelity, Into the Wild, The Muppets, Spider-man 3 and many more, is currently on location in Baton Rouge, Louisiana, mixing music for the feature film, Pitch Perfect 2.


NORTHRIDGE, California — Music mixer Joseph Magee, whose impressive credits include Saving Mr. Banks, Pitch Perfect, High Fidelity, Into the Wild, The Muppets, Spider-man 3 and many more, is currently on location in Baton Rouge, Louisiana, mixing music for the feature film, Pitch Perfect 2. For this music-heavy project, Magee is putting HARMAN’s JBL Professional flagship large-format M2 Master Reference Monitors to the test. Recently signed by Hollywood’s TODDSOUNDELUX, where he is responsible for the company’s expanding music services, Magee chose the M2 system for projects at TODD-SOUNDELUX’s Hollywood facility. For Pitch Perfect 2, Magee transported his JBL M2 monitors along with a pair of JBL LSR308 studio monitors to Baton Rouge, where the film is in production. The music recording studio for the project was built specifically for the film in an existing 4-story warehouse structure.

With the objective of recording 95 percent of all the on-camera a cappella performances in a new, untested studio environment, Magee relies on the M2’s ability to provide exceptional performance in any production environment. “I’ve been using the M2 monitors in my music dub room at TODD-SOUNDELUX and I’m now getting accustomed to using them on the road,” Magee said. “I think a lot of people perceive the M2’s as monitors that are meant to be permanently installed in a control room, tuned to the room and then left alone. But the reality is these loudspeakers sound great out of the box, so taking them to Baton Rouge was an easy decision.” With the dynamic range needed for film production yet with a footprint of only 20 feet wide by 14 feet deep, the M2 is finding its way into smaller rooms where traditional cinema speakers are prohibitive. With included room EQ, the M2 system can deliver accurate response in any mix environment. 

Having used other large-format studio monitors, in Magee’s opinion, JBL’s patented-pending Image Control Waveguide, coupled with JBL’s patented low-distortion D2 high-frequency driver sets the M2 apart from the pack. “The waveguide is so darn fast, I’m hearing things I haven’t heard before in my mixes and I’m hearing things differently—in a good way,” he said. “At the TODD-SOUNDELUX facilities, all the engineers who have come through have been shocked at how authoritative these M2 loudspeakers are and they’ve been amazed at the clarity of the system.”

In addition to the M2 system, Magee uses a pair of JBL’s powered 3 Series LSR308 studio monitors as his near-field listening system. In a portable, “bookshelf”-size format, and available at an entry-level price, the 3 Series studio monitors share the Image Control Waveguide technology developed for the M2 to provide detailed imaging. “In all honesty, when I was first auditioning the M2 system at TODD-SOUNDELUX, I didn’t fully understand what I was working with,” Magee noted. “But then I worked with the 308 monitors at home and it all clicked for me. I simply wasn’t used to the imaging and level of detail these
speakers provide.”

To further meet Magee’s needs, JBL custom-designed a panel in its HARMAN HiQnet System Architect™ software that enables Magee to quickly create a simple, 4-band Room EQ in the DSP of the Crown I-Tech 5000 HD amplifiers being used to power the system.

Looking towards the future, Magee sees no boundaries for the M2. “I envision a lot of opportunities for differentapplications with the M2,” he said.
