Utopia is entirely designed, developed and manufactured in France, in our workshops in Saint-Etienne. A unique and internationally recognized expertise for nearly forty years.

'W' sandwich cone
The ‘W’ sandwich cone perfectly optimises the frequency response curve by fully mastering the three key parameters of lightness, rigidity and damping. When listening through the ‘W' sandwich cone, the sound is completely transparent with extremely little distortion.

TMD® surround 
Originally developed for the Sopra line of high-fidelity loudspeakers, our TMD® (Tuned Mass Damper) surround has a unique profile, designed to better control the effects of resonance and to drastically reduce the distortion associated with deformations of the cone. The speaker driver takes advantage of this patented technology by spreading better defined and very realistic midranges.

Progressive spider
The progressive spider used on all our Utopia drivers is built around a progressive section that reproduces all the impact of the bass whilst optimising the linearity, precision and dynamics of the sound.

Bi-amplification crossover 
All the components on our crossover have been specially selected and optimised to better control the effects of thermal dissipation. These components, essential for managing different channels and the soundstage, have improved reliability. As for the bi-amplification, this enables the woofer and tweeter to be driven separately in terms of power, resulting in optimum performance.
