JMC Lutherie - Jeanmichel Capt, the Luthier

JMC Lutherie SA is a Swiss manufacturer of acoustic speakers in tonewood, resonance supports for striking watches and guitars.

Jeanmichel Capt, the Luthier, a worthy descendant of the famous inventive and creative watchmakers from the Vallée de Joux region, is the creator of the Soundboard, the acoustic speaker that revolutionizes the music listening experience.


Finishes, colors and artwork

The Soundboard is available in a natural shade, a violin-type progressive version, black or white or personalized color. In all cases, lutherie varnishes are used in order to preserve the lightness, the vibration and thus the sound quality. It is also possible to have a printed reproduction made. An artist can also express his/her talent on this surface.

The Soundboard's sound qualities

According to studies by the EPFL - Swiss Federal Institute of Technology in Lausanne, the Soundboard has exceptional technical and sound qualities; an exceedingly low distortion rate, extremely fine restitution, a natural stereophonic effect (due to its restitution by a single speaker) and extremely long persistence of the sound in a large area. The harmonic distortion rates for example fall within a range 5 to 10 times lower than a traditional good-quality loudspeaker, meaning around 0.05 % compared with 0.5 %.

350 year-old resonance spruce

Resonance spruce, used for the Soundboard, is the fundamental type of wood chosen by stringed instrument makers. This wood combines lightness, ensuring an excellent response to vibrations, with rigidity and tonicity guaranteeing substantial mechanical resistance. Combined with time-honoured lutherie techniques and contemporary audio technology the result is a truly exceptional loudspeaker; the Soundboard.

A very natural stereophonic effect

The Soundboard is a speaker capable of singlehandedly reproducing the stereophonic sound environment contained in records. One thereby achieves an extremely natural restitution of the original stereophony. This system also serves to eliminate the interferences engendered by the fact that each recorded sound source is reproduced from two separate speakers. This quality results in far more natural tones.”
