In 2004, engineer Pierre-Emmanuel Calmel, invented the Analog Digital Hybrid (ADH) audio technology that is the basis of Devialet's products. Three years later, in 2007, he developed an amplifier prototype using the ADH technology, and founded Devialet along with Quentin Sannié and Emmanuel Nardin.[1][2] At the company's founding, Sannié served as CEO[3] and Calmel as CTO.[4]

Devialet introduced its first product to market, an amplifier called "D-Premier," in 2010.[5] Between 2010 and 2012, Devialet raised over €17 million in funds from a variety of investors.[6]

In June 2013, the company unveiled an updated version of its D-Premier amp changes (known as the Devialet 240) and two new lower-end versions, the Devialet 110 and Devialet 170.[7] In late 2014, the company announced the release of its first speaker, the Devialet Phantom. The speaker was made available in Europe in early 2015.[8] In June 2015, it raised €17.5 million ($20 million) in another round of funding led by previous investors. The purpose of this funding round was to bring the Phantom to the United States market.[9]

Devialet released two new products in 2016: the "Gold Phantom" speaker capable of producing sound volumes of up to 108 decibels[10] and the Expert PRO amplifier.[11] In November 2016, Devialet raised €100 million in a funding round led by Foxconn,[12] Jay-Z's Roc Nation, and other investors.[13]

In July 2017, Devialet entered into a partnership with the British-based media company Sky to create a soundbar designed for televisions called the "Sky Soundbox."[14][15] In October, it entered into a 10-year agreement with the Paris Opera to build a "sound discovery room" in the Palais Garnier.[16] The company also entered into a partnership with Renault to build car audio systems and demonstrated a prototype version for Renault's SYMBIOZ concept car in December 2017.[14][17]

Quentin Sannié, who had been the CEO of Devialet from its foundation, stepped down from the role in March 2018 and was replaced by Frank Lebouchard.[3]

Devialet devices use several audio technologies developed by the company, marketed under these names:

• Analog Digital Hybrid (ADH)[19] combines elements of analog amps (Class-A) and digital amps (Class-D), allowing for larger wattage and decibel peaks.
• Heart Bass Implosion (HBI) is a technology that provides broader coverage of low-frequency sounds[29] and mimics the properties of a subwoofer.[8]
• Speaker Active Matching (SAM) is a signal processing mechanism that analyzes and adjusts sounds in real-time to "reproduce the exact acoustic pressure recorded by the microphone."
• Active Co-Spherical Engine (ACE) refers to the spherical shape of some Devialet devices (namely, the Phantom speakers) is an acoustic architecture designed to deliver sound in every direction.[29]
