Heritage Series
The SUPRAVOX speakers of the Heritage series are directly inspired by the brand's legendary products.

This brand new loudspeaker takes up the original cone of the mythical T. 215 SRTF wideband of the sixties.
We started from original models in order to find the sound qualities that have satisfied music lovers over the past decades.

The new Alnico motor, developed using FEA software, is designed around a central magnet of one kilogram of Alnico 5. This arrangement makes it possible to capture 100% of the energy from the magnet. The magnetic field reaches 1.2T in the 8mm gap.
The profile of the pole brings a perfect symmetry of the Bl(x) curve, with an excursion of 3.2mm, and generates less distortion.

We have designed a new spool, light, in copper-plated aluminum wire, on Nomex support.

A thorough study of the treatment of the membrane ensures a linear response, and very extended.

The addition of the original bicone, in very thin and light paper, stiffened by a specific treatment, makes it possible to extend the response up to 20kHz.

High-Precision Craftsmanship: Made in France

Each Supravox loudspeaker inherits expertise born in the 1950s. From the iconic 215 RTF 64 to today's innovations, our loudspeakers are entirely hand-assembled in our workshop just outside Paris. A French standard of perfection that defies time to deliver pure musical emotion.

  • The Artisan's Touch

    At the heart of our factory on the outskirts of Paris, each voice coil is hand-wound with micrometric tension. We use ultra-light supports and high-purity conductors to minimize moving mass. It is this extreme lightness that gives our loudspeakers their legendary responsiveness and their ability to reveal the finest details.

  • The Hand and the Spirit

    Each loudspeaker is a unique piece, assembled by craftsmen whose expertise has been passed down for decades. The precision of the centering and the tension of the suspensions are adjusted by touch, a sensitivity that no machine can replicate. This artisanal assembly guarantees perfect fluidity of movement and exceptional longevity.

  • Exponential Paper Cones

    Our cones are made from a proprietary recipe of long-fiber paper, manually processed to achieve an ideal balance of rigidity and damping. The exponential profile, pioneered by Supravox, ensures homogeneous sound diffusion. The result is an organic timbre and strikingly realistic vocal presence.

  • Magnetic Alchemy

    Beyond the simple magnet, we master energy. In our factory on the outskirts of Paris, we forge Alnico 5 motors and Field Coil systems capable of saturating the air gap with absolute precision. This controlled power offers lightning-fast dynamics and almost zero distortion, hallmarks of Supravox's high sensitivity.

  • Signal Purity

    Perfection often comes from subtraction. By designing full-range loudspeakers capable of covering most of the spectrum, we eliminate the need for crossover filters. The signal travels directly from your amplifier to the cone, preserving perfect phase coherence and a holographic soundstage of complete transparency.

  • Tested for Eternity

    Each unit leaving our workshops undergoes a rigorous testing protocol: frequency analysis, impedance measurement, and tactile inspection of the excursion. But the final verdict belongs to the human ear. Each loudspeaker is validated by our technicians, ensuring that your investment will remain an exceptional instrument for decades to come.
