Supravox manufacturer of speaker drivers, kits and speakers
Before World War II, the company SEM – “Super Electro Mecanique” – of 26 rue Pierre Lagny, Vincennes, created by M. DORLIAC, a former marine engineer, a high quality mechanical engineering manufacturer, started making 12 cm electromagnetic loudspeakers for use in radios. A manufacturing facility in Joinville completed the enterprise.
At the same time, at the start of the 30s, M. LEGORJU created AUDAX, and commenced manufacturing in Montreuil.
Shortly after the war, M. LIEBERT, SEM’s director of research and manufacture, developed the first exponential membranes, before launching the first full range loudspeakers of 17, 21, 24, 28 and 33 cm on the market. According to our sources, at this time, only the American company University made a comparable speaker.
The first SEM Alnico speakers were made between 1945 and 1950. Loudspeaker aficionados of that era preferred Alnico or Ticonal.
An anecdote: Vitruve or Vitruvius, of the first century BC, was a military engineer and architect who wrote an architectural treatise which was very much in vogue in the 15 th century. It dealt particularly with the building of theatres of acoustic qualities which have never ceased astonishing the architects of today.
In 1956, Madame DORLIAC, who was of Italian origin and was connected with the manufacturer “RADIOPHONO et d’ELECTROPHONO”, registered the trademark SUPRAVOX. She occupied the former offices of M. Henri de France, inventor of the SECAM process, at 46 rue de Vitruve, Paris. This was the start of production of speakers under the SUPRAVOX name, and the foundation of all research and manufacture by SEM, in particular of its exponential membranes and highly sensitive full range speakers.
During the same era, the company SIARE was founded by a former employee of SEM.
Elsewhere in the world, the Germans preferred to work with radial membranes, as opposed to the Americans, who at ALTEC worked with exponential membranes.
During the 1950s and 60s, the TV and radio manufacturing consortium led by M. Sylvain FLOIRAT, CGTVE (Tévéa, AMPLIX, TELMASTER, AIRPHONE …) consumed almost all SUPRAVOX speakers, in particular the models equipped with Ticonal motors with reinforced cylinder heads.
Between 1958 and 1960, SUPRAVOX participated in acoustic isolation studies for the cabin of the Concorde.
