Raising the Standard for Ultrahigh-end Luxury Audio

The JBL Synthesis M2 Pro Master Reference is a 2-channel floorstanding or soffit mountable reference speaker system. 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 and home cinema requirement for impactful dynamic range presented by the latest high resolution, high dynamic range sound formats.

Note: Currently only sold as a complete JBL Synthesis M2 Pro system: 2 x M2 Master Reference Speakers, SDEC4500 digital crossover, 4 x Mark Levinson No531H and S4500XLRIC cables (other package options can be assembled, please contact us to discuss).

Dual Diaphragm Dual Voice Coil Compression Driver:

The revolutionary D2 Dual Driver dramatically improves the sound and performance of high frequencies, providing an extreme output advantage over conventional systems with significantly higher array power, reduced distortion, double the number of voice coils and more than double the power handling. This results in a dramatic increase in pure high frequency sound pressure levels in the same physical footprint with a 30% reduction in weight.

A revolutionary device that merges two compression drivers into a single compact transducer, establishing a new benchmark for pure high frequency output and low distortion. Dual Diaphragms Provide Increased Radiating Area for Higher Output

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.

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 wave guide 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.

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.
