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.

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. Together with ADH*, this technology allows Phantom to reproduce levels of sound at the edge of infrasound (16Hz).

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.

Thanks to the EVO Platform, your system keeps getting better everyday, without even requiring your intervention.  Even after setting it up in your home, Phantom permanently upgrades itself for free, makes its internal connexions evolve, and continually gets better. Because Devialet practically acts against systems’ obsolescence...
