The new, patented M profile membrane is the fruit of many years of research and our expertise in membrane materials and geometries. The innovative "M" profile, produced in a single piece (without a core cover), provides exceptional rigidity, and perfectly combines the three criteria needed to create the "ideal" loudspeaker: rigidity, lightness and damping. The result is an extremely linear frequency response, low distortion and improved sound dispersion thanks to its shallow depth.
THE MANY ADVANTAGES OF THE "M" PROFILE :
- very wide bandwith, control and damping of resonances;
- reduced harmonic distortion;
- better sound dispersion thanks to its geometry and angle of inclination;
- reduced voice coil depth, for a smaller driver footprint ;
- optimal power handling thanks to the possibility of integrating large coils.
When you listen to it, this diaphragm provides a striking level of detail and realism, transporting you right to the heart of the music.

REMOTE AMPLIFIER IN CURRENT MODE
The most transparent and natural
Since main monitors are frequently soffit-mounted, these require external electronics for this application. Focal engineers have therefore developed an amplification system combining a class H with a current mode. By controlling the current (instead of the voltage), it is possible to directly control the force submitted to the membrane and eliminate any unwanted artefacts. Combined with analogue filtering and exceptional drivers, this amplification achieves the lowest THD ever measured in an anechoic chamber.
"M" profile Béryllium Tweeter
Rigidity and Purity
Patented by Focal, the pure beryllium ‘M’ profile tweeter combines rigidity, lightness and damping for exceptional high-frequency reproduction. The ‘M’ membrane is the result of many years of research and expertise. Made in a single piece, it improves sound dispersion, reduces distortion and ensures optimum power handling.
Infinite Horn Loading
High-definition sound
For the Beryllium tweeter to deliver all its finesse, it would need an almost infinite volume. Sopra's need for compactness meant that the maximum volume of the cabinet had to be used for the bass. Exploring new ways of loading the tweeter led us to imagine the IHL infinite-load horn. The IHL (Infinite Horn Loading) system enables the Beryllium tweeter to be loaded while respecting the compactness of the loudspeaker. The rear wave is gently and progressively absorbed to avoid distortion. The result is maximum definition.
