Cabasse is a French audio manufacturer founded by Georges Cabasse in 1950. It is mainly known for its home
loudspeakersbut has also produced professional audiospeakers for studio recording or sound reinforcement in theatres and power amplifiers.

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
honeycombmembranes that allowed high power with low distortion. These membranes were used by the very small "Galliote" (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.
La Géodewas inaugurated, and it remains the only 12-channel Omnimax in the world. For special low frequency effects, 4 giant subwoofers (100 cubic feet for 2000 lb) fitted with 2 x 22 inches honeycomb membranes complement this 12.1 system.
In the nineties, Cabasse started to work on
coaxialunits 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. This system, released in 2007, is called La Sphère and consists of two spheric coaxial speakers, a filter and four power amplifiers.
