 Sopra N°3
Innovation
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

Stabilising the magnetic field
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 optimising the suspension profile which controls the resonance in order to drastically reduce distortion and increase the definition of bass and midrange.

DETAILS
The main theme of Sopra is deliberately uncluttered, though it still offers connoisseurs the opportunity to enjoy all the small details. The grille with an incremental meshing motif protects the Beryllium tweeter and gives it a strong identity. This motif is repeated for sealing the curved back panel of the middle section. The terminal board, the thumb nuts and the adjustable spikes have all been specially designed for Sopra, as have the few visible screws, all of which were manufactured by watchmaking experts.

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 favours performance, whilst exceptional materials associated with different lacquered finishes or wood finishes in oak (Light Oak and Black Oak) with High Gloss varnish for a radiant shine bringing even more elegance and warmth to your home decor.

Substantial efforts were made to give the front a tidy appearance 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).
