Sopra n°2 clearly inaugurates a new era for the “Premium High End” by taking into account new performance criteria. Compact, modern, a pure design,character... all these are essential factors to ensure perfect integration into your interior.
Equipped with best midrange drivers ever developed by Focal, with the NICand TMD technologies, Sopra n°2 pushes back the limits of sound reproduction in terms of transparency in a very compact enclosure. Indeed, unlike Utopia, which is extravagant by essence and where size is by no means a constraint, Sopra aims for maximal compactness to ensure easy integration into reasonably sized rooms.
Stabilising the magnetic field
Since the beginning, we have always had a great interest in the magnetic circuit, an essential aspect of a speaker drive unit. The precision and detail of audio reproduction depends on the stability of the magnetic field.
After having pushed back the limits in electromagnetic technology with the Grande Utopia EM and the Stella Utopia EM, our engineer discovered that the magnetic field varies regardless of its intensity. Indeed, it is not stable because it is modulated by three factors: the movement of the voice coil (Lenz's law), the current passing through it (Foucault current) and the frequency. Consequently, the voice coil, the moving part, is in the magnetic field which becomes too variable, and this leads to loss of precision.
The NIC technology lies in a Faraday ring whose dimensions, materials and positioning we were able to optimise to make the magnetic field be no longer affected by the position of the voice coil, by the amperage or the frequency of the current passing through it. This solution permits to control the magnetic field to decrease the effects of distortion and give the sound a very high-definition and an unprecedented dynamic.
The obsession with the midrange
The midrange register is no doubt the most complicated to control in a sound system.
Thanks to the power of finite element analysis, our teams have revealed resonances which alter definition in the suspension which connects the cone to the basket
The solutions already known for increasing the damping properties of the suspension all result in an increase of the mass which consequently alters definition. The answer came from a technology used in earthquake-resistant skyscrapers and which is also used for the suspension on racing cars. This technology is called a "Tuned Mass Damper": an additional mass oscillates in opposition to the resonance frequency to control it.
Our Tuned Mass Damper consists in simply two tubular rings on the suspension to avoid deformation of the cone without afflicting the dynamics. Itreduces drastically the distortion and increase the definition.
Getting the most out of the Beryllium tweeter
BEYOND AESTHETICS AND SHAPE
The Sopra line is destined for the most passionate sound enthusiasts. Its design favours performance, whilst bringing together the qualities expected of an object which will be integrated into very elegant interiors and décors. Lacquered or bloodwood finishes are associated to noble materials to create an elegant line. Substantial efforts were made to give the front a tidy appearance, particularly around the speaker drivers, to iron out any aspects which could afflict the acoustics or the appearance.
Sopra’s very structure is articulated around the intermediate section. This injected polyurethane component allows for the upper and lower cabinets to be inclined for the "Focus Time" (acoustic convergence of the channels). It also provides the freedom to achieve the desired enhancements for the treble (decompression, isolation of the tweeter section...). It contributes to the very high rigidity of the structure as a whole and its compactness optimises the use of space for the midrange.
