These extremely rare and legendary Elipson BS50s are among the absolute milestones in the history of high-end loudspeakers. The BS50 was designed in 1953 for the very first “sound and light” show at the Château de Chambord and grew into the model that definitively put Elipson on the map.
What makes this first generation so special is not only the design, but also the construction. These early BS50s were entirely handcrafted in plaster , a mixture of gypsum and natural fibers that proved exceptionally suitable for the spherical housing. It is precisely this technique that makes this first generation so rare and desirable today.
The sculptural form almost automatically turns these speakers into works of art. The acoustic sphere and the famous reflector, often described as the emblematic “ear,” ensure that the sound is directed into the room in a precise and particularly spatial manner. Elipson developed this principle from the research of Joseph Léon , who wanted to concentrate and disperse the acoustic energy of the driver via reflector and spherical shape with maximum precision.
That is precisely where the unique character of the BS50 lies: in addition to the specific qualities of the acoustic sphere, there is exceptional purity in the sound projection , causing music to detach from the cabinet and move freely through the space, as it were. This makes this set not only technically remarkable but also emotionally impressive for those who listen to it.
Moreover, the BS50 is the model that defined Elipson's identity. Elipson itself calls the BS50 the model that embodies the history of the brand. The brand dates back to 1938 and built a strong reputation in France from the mid-20th century onwards, partly through major public events and professional applications.
It is extremely rare today to hear a set of BS50s playing, let alone see an authentic first-generation set for sale. For music lovers, collectors, and connoisseurs of early high-end audio, this is an exceptional opportunity to bring one of the most iconic French loudspeakers ever made into your home.
True one-of-a-kinds.
Rare, historical, and visually unforgettable.
