Devialet was founded in 2007 by engineer Pierre-Emmanuel Calmel following his revolutionary discovery which changed the sound amplification: the ADH® Intelligence. This first invention made possible the hybridization of the digital and analogue technologies for a sound with an unrivaled quality. With Quentin Sannié, visionary entrepreneur, and Emmanuel Nardin, designer of the excellence, they formed a trio, leading Devialet towards global success.
