CLASSIC Series
The goal of the Classic Series is to maintain Supravox's philosophy of developing high-efficiency full-range loudspeakers. We are working to further expand the useful bandwidth for the highest possible performance, while constantly improving the definition, quality and linearity of response. From diameter 135 to 380 mm, the audiophile can satisfy his passion.
This woofer, with very high dynamic qualities, has been developed to harmoniously overlap with any high-efficiency horn system.
This speaker charges in a Bass-Reflex of 40L tuned to 60Hz, i.e. a PVC vent of 125mm by 9cm long, offering a cut-off at 65Hz. Listening to it, it reveals itself as a bass reinforcement of great finesse.
It can be used in pure low-medium in a closed volume of 10 to 12L.
With its 96 dBspl/2.83V at 1m sensitivity, the challenge of high efficiency is achieved and this with a wide linear travel without dynamic compression (+/- 3.7mm). Power handling is the highest of any Supravox 215.

High-Precision Craftsmanship: Made in France
-
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.
