A New Benchmark in High-Fidelity Sound

The Devialet Phantom Ultimate 108 dB sets a new reference point for what an all-in-one speaker can achieve. Designed to reproduce music with stunning accuracy and depth, it combines advanced engineering, radical design, and unmatched acoustic performance. At 108 dB of maximum sound pressure level, it delivers room-filling sound that feels both physical and emotional.

Power Beyond Expectations

With a total amplification power of 1100 watts, the Phantom Ultimate 108 dB can handle everything from subtle acoustic textures to the most demanding electronic beats. The immense headroom ensures that dynamics are always preserved, even at the highest listening levels, giving listeners the impression of a live performance.

Revolutionary ADH® Amplification

At the heart of this speaker is Devialet’s exclusive ADH® (Analog Digital Hybrid) technology in its latest generation. By combining the purity of Class A analog with the efficiency of Class D digital amplification, it achieves crystal-clear treble, natural midrange, and thunderous bass—all perfectly synchronized.

Speaker Active Matching (SAM®) Precision

The SAM® technology ensures precise control of the woofers, allowing bass to extend down to an impressive 14 Hz without distortion. This means you feel the full physical impact of low frequencies, creating a truly immersive experience that traditional speakers cannot replicate.

Heart Bass Implosion (HBI®) for Deep Impact

Devialet’s HBI® technology allows the speaker’s compact form to deliver bass normally associated with massive subwoofers. Two push-push woofers work in perfect harmony, producing extreme low-end power while canceling unwanted vibrations.

Advanced Acoustic Architecture

The Active Cospherical Engine (ACE) ensures that sound radiates evenly in all directions. This spherical design eliminates diffraction effects, creating a wide sweet spot so every listener in the room experiences the same clarity and precision.

Refined Design Evolution

The Phantom Ultimate 108 dB has undergone significant design refinements. Its redesigned tweeter grid improves high-frequency detail, while the dust-cap-free woofers enhance both durability and aesthetics. With finishes like Light Pearl, Deep Forest, and Opéra de Paris, it is as much a design object as a high-end sound system.

Seamless Connectivity

Equipped with Wi-Fi 6, Bluetooth 5.3, AirPlay, Google Cast, Spotify Connect, Tidal Connect, UPnP, and Roon Ready, the Phantom Ultimate integrates effortlessly into any modern digital ecosystem. An optical input and Ethernet port expand connectivity for home cinema setups and wired networks.

Personalized Listening Experience

Through the Devialet app, users can tailor their listening with Music, Movie, and Podcast modes, as well as a neutral Monitoring mode. A 6-band equalizer and options like Adaptive Volume Leveling (AVL™) and Night Mode give complete control over the sound signature.

Intelligent Power Supply (PSU)

The latest-generation PSU® technology ensures maximum efficiency while minimizing power consumption. This allows the Phantom Ultimate to sustain high volumes over long listening sessions without overheating or distortion.

Compact Yet Powerful

Despite its compact form (246 × 255 × 342 mm) and manageable weight of 11.1 kg, the Phantom Ultimate 108 dB competes with and often outperforms much larger systems. Its unique combination of power, design, and technology sets it apart in the world of high-end audio.

A Vision of the Future of Sound

The Phantom Ultimate 108 dB is more than a speaker—it is an acoustic sculpture designed for future-proof performance. By integrating the most advanced technologies and streaming protocols, it offers an experience that evolves with you, ensuring years of cutting-edge listening pleasure.
