Devialet Technology.

The beating heart.

Living inside Devialet Phantom Ultimate, core Devialet innovations attest to fearless acoustic engineering. Protected by over 200 patents, they continuously challenge the possibilities of sound reproduction, delivering pure, physical audio—with zero distortion, saturation, or background noise. Each technology—foundational or newly invented—drives the Devialet Phantom legacy forward, forever in pursuit of excellence.

ADH® Analog Digital Hybrid

A true breakthrough in high-end amplification—then and now. The cornerstone of Devialet’s engineering legacy, latest-generation ADH® (Analog Digital Hybrid) technology seamlessly fuses the refinement of analog with the power and compactness of digital, delivering breathtaking clarity—up to 35 kHz.

HBI® Heart Bass Implosion

Originally developed for Devialet Phantom, HBI® (Heart Bass Implosion) technology reaches deeper into infra-bass—down to 14 Hz in an ultra-compact speaker environment. Built to perform under extreme pressure, two lateral woofers thrust together in an airtight architecture. The result: sound so physical, it moves you.

SAM® Speaker Active Matching

Fidelity—taken to the extreme. Devialet SAM® (Speaker Active Matching) software achieves absolute fidelity without compromising the speaker’s unique characteristics. Adapting in real time to both transient and steady-state signals, SAM® enables Devialet Phantom Ultimate to reproduce phase and amplitude with stunning precision.

AVL® Adaptive Volume Level

Devialet’s Adaptive Volume Level (AVL™) technology automatically adjusts volume in real time to suit the content being played—ensuring the smoothest possible listening experience. AVL™ brings cinematic-standard sound to Devialet Phantom Ultimate. From whispered dialogue to explosive action, don't miss a single beat.
