Audio solutions


A company that pushes sound to its limits with the desire to offer professionals, enthusiasts and music lovers a sonic reality they have never been able to enjoy or even experience. Such a sound is the result of a passionate journey of craftsmanship and high quality materials to bring Excelson Soundboards to life since 2020.

We offer a sound that touches and transforms your musical sensibility.

It all began when Jean-Marc Dietrich discovered the resonant spruce soundboards made by Jeanmichel Capt of JMC Lutherie SA. He was deeply touched by the warmth and immersion that the Soundboards brought to each of his concerts as a guitarist. When JMC Lutherie SA ceased its activities, the desire to continue to give life to these incredible products and to make them available to the public was instantaneous. In 2020, Jean-Marc Dietrich created Excelson SA with a few friends to fully exploit the potential of this innovative audio solution.

Our vision:

To offer to the greatest number of people a touching and immersive sound produced by the resonance wood


From the forest to the showroom, Excelson’s products are produced by local craftsmen with outstanding expertise. The involvement of these different actors is the key to the quality of Excelson’s various audio solutions.
