Forget what you think you know. Unlike any wireless speakers that have gone before, Phantom Premier's revolutionary technologies fuse together to deliver an intense emotional experience. One you can literally feel in your bones.

Plug, play and unleash the physical impact of a high-end ultra-dense sound with power, clarity and precision like nothing you've ever encountered.



This is Phantom Reactor, a new breed of wireless speaker. By stretching size and performance beyond reasonable limits, Devialet engineers have brought to life the only ultra-compact home sound system capable of delivering high fidelity and physical impact, whatever volume you listen at. Insanely powerful. Defiantly small.


Every day, Devialet engineers, mechanics, electricians, IT and signal processing experts come together in their Paris ateliers. They work tirelessly towards the same goal: inventing the sound technologies of tomorrow.

Founding invention of Devialet, the Analogue Digital Hybrid or ADH®, is a revolutionary technology that succeeds for the first time in combining the refinement and musicality of Analogue amplification (or Class A) with the power and compactness of Digital amplification (or Class D).

Following the same principle as the power steering of a car, the analogue amplifier generates the voltage of the speaker, while four digital amplifiers give it its energy power.


The Active Cospherical Engine (ACE) designates the spherical design of Phantom, inspired by the pulsating sphere of Olson, perfect acoustic form.

Like the wave created on the surface of the water when you throw a stone at it, the sound extends through space in concentric waves. The sphere is thus the ideal form when it comes to reproducing a sound and diffusing its energy linearly in all directions.

Inspired entirely by the laws of acoustics, Phantom's functional design ensures an omnidirectional emission for a sound image with striking relief whatever the listening angle and without diffraction of sound on the surface of the speaker.


Where ADH® is the engine that imposes the signal on Phantom, SAM® (Speaker Active Matching) is the technology allowing this engine to adapt the sound signal so that its speakers reproduce exactly the sound pressure of the music source.

The role of an enclosure is to reproduce the air movements generated by the source and captured in the sound wave by the microphones during recording. But each speaker has its own physical characteristics which mechanically alter the sound in this last stage of acoustic reproduction.


To create an ultimate audio experience transmitting all the physical impact of music from a compact design, Devialet engineers designed Heart Bass Implosion (HBI®), a revolutionary acoustic architecture pushing the system's efficiency and compactness electroacoustics to its limits. Defying the laws of physics, this architecture is capable of delivering an unequaled level of bass for a system of this size.


Designed, manufactured and assembled in France, Devialet systems demand extreme precision engineering and ultra-high-performance materials. A ceremony of inimitable gestures. Nothing less than perfection. This is the Phantom ritual.
