Cabasse is a French audio manufacturer founded by Georges Cabasse in 1950. It is mainly known for its home loudspeakers but has also produced professional audio
Professional audio
Professional audio, also 'pro audio', refers to both an activity and a type of audio equipment. Typically it encompasses the production or reproduction of sound for an audience, by individuals who do such work as an occupation like live event support, using sound reinforcement systems designed for...

  • 1950 : Foundation.
  • 1952 : First 2-way coaxial speakers
    Coaxial speakers
    A coaxial loudspeaker is a loudspeaker system in which the individual driver units radiate sound from the same point or axis. Two general types exist: one is a compact design using two or three speaker drivers, usually in car audio, and the other is a two-way high-power design for professional...

Notable products and technologies

Cabasse is one of the oldest loudspeakers manufacturer in France, and is known for its involvement in research, its high standard of quality, and the names of their products that used to be related to sea (especially boat names like clipper, sampan, ketch, sloop...)

In the eighties their reputation came from their professional active speakers (often used by recording studios) and the honeycomb

 membranes that allowed high power with low distortion. These membranes were used by the very small Galiote (home hi-fi) and the huge Saturn, a subwoofer for theatres, fitted with a 22 inches unit. They also used to perform astounding comparisons between live sound and speakers sound and therefore focused their goals on high dynamics (for real sound pressure levels), high efficiency and low distortion levels.

In 1986 La Géode

 units in order to reduce directivity through spherical wavefront. This is their Spatially Coherent System principle. It was implemented through the TC21, a 3-way coaxial unit whose bandwidth goes from 200 Hz to 20 kHz with an 30° off-axis response very close to the on-axis response.

At the beginning of 2006 they unveiled a high-end 4-way unit and presented the theoric approach in a paper at the Audio Engineering Society
