The world most critically acclaimed start-up for the excellency of its innovations in sound technologies

Devialet is a French company created in 2007 from the encounter of 3 complementary and explosive expertise: Pierre-Emmanuel Calmel, an engineer, Quentin Sannié, a visionary entrepreneur and Emmanuel Nardin, a designer of excellency.

Together they founded Devialet, Ingénierie Acoustique de France

Devialet origin: an invention which revolutionizes sound processing.

Pierre-Emmanuel Calmel invented a revolutionary technology that transformed sound amplification:
The ADH Intelligence. the first hybrid technology that associates the preciseness of Analog amplification (Class A) to the power of Digital amplification (Class D) allowing Devialet products to reach a never heard before sound quality.

With the combination of Devialet's exclusive audiophile inventions, including ADH® and HBI®, 
Phantom emits an ultra-dense sound with physical impact, with no background noise, no saturation, no distortion all the way up to 3000 Watts.

Behind all these extraordinary performances, three key inventions

Analog Digital Hybrid ADH®

Invented by Devialet, ADH Intelligence is a technology that has succeeded for the first time in combining the sophistication of the Analog amplification (Class A) and the power and compactness of the Digital amplification (Class D). This technology, also included in Devialet’s Expert products, amplifies the sound signal with utmost clarity and transparency.

Heart Bass Implosion HBI®

Developed for Phantom, HBI® is the only system in the world that allows for extremly low frequencies to be emitted from such a compact space . Absolutely revolutionary, Phantom is built around two hermetic woofers that function under high pressure. The powerful beats of the lateral domes produce a unique ultra-dense sound with physical impact.

Active Cospherical Engine Loudspeaker ACE®

The ACE® Loudspeaker technology (Active Cospherical Engine) designates the spherical conception of Phantom, inspired by the thrusting sphere of Olson, the perfect acoustical shape. It is the ideal shape to reproduce sound and spread it's linear energy in all directions. Phantom has the perfect acoustic architecture for an omnidirectional emission with a homogeneous sound no matter the listening angle and without any sound diffraction at the surface of the speaker.

An ultra dense sound with physical impact

Phantom's ultra dense sound creates intense emotional experiences. 

Uncover the richness of songs you have heard a thousand times in all their amplitude, from sub bass at 16hz to ultra sharp sound at 25kHz with no background noise, no saturation, no distortion, all that up to 3000 Watts and 105 Decibels of power.
