High Performance 2 - way High-End Bookshelf Loudspeaker

They feature an '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, the very low distortion gives it incredible clarity and very high definition combined with the spectacular spatialization typical of bookshelf loudspeakers.It features 'NIC' magnetic circuit, 'TMD' surrounds for the midrange woofer & Infinite Horn Loading ( IHL ) tweeter. 

Beyond this attractive first impression, what's 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 understanding of the music.

Sopra 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.

Stabilizing the Magnetic Field with a Neutral Inductance Circuit

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. NIC technology ( Neutral Inductance Circuit ) permits to control the magnetic field and finally enables to master it in order to limit distortion. It decreases the effects of distortion and give the sound a very high-definition and an unprecedented dynamic.

The obsession with the Midrange & Tuned Mass Damper 

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. "TMD" technology consists of optimizing the suspension profile which controls the resonance in order to drastically reduce distortion and increase the definition of bass and midrange.

Infinite Horn Loading

Our 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. But the requirement for Sopra to be compact meant that as much of the cabinet as possible had to be used for the bass. We had to explore other options for loading the tweeter, which led us to come up with the IHL system. The "IHL" system enables to load the Beryllium tweeter respecting the compactness demand of the speaker. The rear wave of the tweeter is delicately and gradually absorbed to avoid any distortion. The treble definition is pushed to the maximum

Mastering the Cabinet & Choice of Materials 

Made in France Sopra’s cabinet was designed in our cabinet-making facility in Bourbon-Lancy (Burgundy, France) using the same manufacturing process as for Utopia The 69 mm sandwich-machined front panel uses the same principle as ‘Gamma Structure’ to provide inertia and damping. Its density gives it the inertia necessary to provide a stable mechanical reference for optimal definition. The inside of the cabinet has no parallel side panels, and small Helmholtz resonators have been added to the lower section to prevent vertical standing waves. We chose glass as the material for the base of the loudspeaker to provide floor coupling, using spikes, which enabled the fastest propagation time possible, thus eliminating all halo effects in the bass.

No Sacrifice of Performance to Aesthetics 

The design agency Pineau & Le Porcher designed Sopra with one rule : No sacrifice of performance to aesthetics. The Sopra line is destined for the most passionate sound enthusiasts. Its design favors 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).
