Compact and powerful, the Focal Sopra N°1 features "NIC" magnetic circuit, "TMD" surrounds for the midrange woofer and Infinite Horn Loading (IHL) of the tweeter. It is a true "demonstrator", corroborating the contribution of the new technologies implemented on Sopra.
First and foremost, the very low distortion gives it incredible clarity and very high definition combined with the spectacular spatialisation typical of bookshelf loudspeakers... What is also astonishing is the texture and smoothness of its sound. It provides a solid, "fleshy" sound with full and articulated bass. Precious is by no means artificial, nor is the limited to the treble. The overall coherence and harmonic richness gives the listener a surprising feel and understanding of the music.
NIC (NEUTRAL INDUCTANCE CIRCUIT)
Stabilizing the magnetic field:
The magnetic circuit is 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, the Focal 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 were optimized 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 allows to control the magnetic field to decrease the effects of distortion and give the sound a very high-definition and an unprecedented dynamic.
TMD (TUNED MASS DAMPER)
The obsession with the midrange
The midrange register is the most complicated to control in a sound system. Owing to the power of finite element analysis, Focal 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. The Focal Tuned Mass Damper consists in simply two tubular rings on the suspension to avoid deformation of the cone without afflicting the dynamics. It drastically reduces the distortion and increases the definition.
IHL (INFINITE HORN LOADING)
Getting the most out of the Beryllium Tweeter:
Focal Beryllium tweeter features an incredibly light and extremely rigid dome, that deliver a transparent and dynamic sound. Its main limitation comes from the compression of air in the cavity behind it, which create interference with the incredible definition. To overcome this, the ideal would be to have a nearly infinite volume. But the requirement for Sopra to be compact meant that as much of the cabinet as possible had to be used for the bass. Exploring other options for loading the tweeter led Focal to come up with the IHL system.
The rear of the Beryllium tweeter is loaded via a small cavity which is connected to the exterior of the enclosure by a horn, and it’s inside is filled with a damping material. Sound waves from the rear of the tweeter are delicately and gradually absorbed. Its acoustic impedance approaches zero so that no resistance alters the movement of the dome. This reduces distortion by 30% and pushes definition to its maximum.
DESIGN: BEYOND AESTHETICS AND SHAPE
The Sopra line 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.
Ideal for small rooms up to 270ft2 (25m2), Sopra n°1 is also ideal for spaces up to 550ft2(50m2). Sopra N°1 is a true little monitor for the home providing high sensitivity and excellent power handling.
Sopra N°1 is supplied with a special stand which has been designed to expel interfering vibrations from the enclosure towards the floor to avoid any colouration. The steel frame inside the floorstander, coupled with the 03⁄4" (19mm) thick glass base using four adjustable stainless steel spikes, provides very high transmission speeds. This is what guarantees an extremely sharp reproduction.
MADE IN FRANCE
Sopra's cabinets are designed in Focal cabinet-making facility in Bourbon-Lancy using the same manufacturing process as for Utopia.
All Sopra speaker drivers are manufactured in France for an optimal products control and the guarantee of a unique sound quality.
The final assembly of all the hifi loudspeakers is done at Focal to ensure a better quality control.
