Timeless sophistication, meet cutting-edge design
Designed and manufactured in France, Devialet Phantom Ultimate 98 dB speaker epitomises French innovation and craftsmanship in every sense.

Each undergoes a meticulous process that combines advanced machinery with the irreplaceable human touch, ensuring it meets Devialet’s high acoustic and aesthetic standards.
Listen Your Way
A refined and robust software architecture brings together an NXP iMX8 processor and the latest Devialet Operating System, DOS3. Enjoy seamless integration with high-resolution streaming protocols and Bluetooth® 5.2 with Wi-Fi 5, delivering enhanced stability and multi-device streaming. The experience enhancement continues through to the Devialet App with unrivalled personalisation options. A six-band equaliser fine-tunes audio rendering, and three dedicated audio modes: Music Mode (your music, as the artist intended), Movie Mode (in-theatre sound, at-home comfort), and Podcast Mode (each episode, like it’s recorded from your living room).


Your Music, In Living Colour
Devialet Phantom Ultimate 98 dB takes this vision further. Every contour, every detail serves the pursuit of a full-body, soul-stirring listening experience. From the front, its compact presence is striking. Move around it, and the elongated body and sculpted side plates emerge, balancing power with elegance. We refined its visual weight without compromising an ounce of force. Built to endure, Devialet Phantom Ultimate 98 dB’s reinforced structure ensures unwavering performance, even at high temperatures.
TECHNOLOGIES
Heart Bass Implosion
Bass You Feel In Your Bones. HBI® (Heart Bass Implosion) pushes the boundaries of infra-bass, reaching depths as profound as 14 Hz within an extremely compact form. Two perfectly synchronised lateral woofers thrust in unison, eliminating unwanted vibrations—for pure impact.
Analogue Digital Hybrid
Analogue, Meet Digital. Devialet ADH® (Analogue Digital Hybrid) next-gen technology achieves the best of both worlds, delivering sound in its most electrifying form—all while consuming less power and reaching crystal-clear frequencies up to 35 kHz.
Adaptive Volume Level
Don’t Miss A Single Detail. Devialet’s Adaptive Volume Level (AVL™) technology uses real-time dynamic equalisation to deliver a smoother, more balanced listening experience. From explosive action to whispered dialogue, nothing is lost on you.
Speaker Active Matching
As the Artist Intended. Devialet SAM® (Speaker Active Matching) software adapts in real time to both transient and steady-state signals, enabling Devialet Phantom Ultimate 98 dB to reproduce phase and amplitude with razor-sharp precision.

Engineered for Immersion
When in stereo, Devialet Phantom Ultimate 98 dB is the closest you’ll come to the soul of a live performance or original recording. Devialet Phantom Ultimate 98 dB’s breathtaking sound stems from a disruptive advance in acoustic engineering. With a cospherical full-range driver seamlessly integrating the midrange and tweeter, every note is rendered with pristine clarity and ultra-precise stereo imaging. Enjoy the most exquisitely lifelike audio you’ve ever experienced: no exaggeration.
Multiroom. Your Music, Wherever You Want It.
Thanks to integrated AirPlay and Google Cast protocols, you can easily play the same music simultaneously on multiple Devialet speakers in your home, or choose to stream different content in each room. Group multiple speakers via AirPlay or Google Cast, and feel the sound sing throughout your space. Google Cast also lets each listener do their thing, controlling their own volume and managing zones with ease: think jazz playing in the kitchen while a podcast is devoured on the couch.


Unleash the Potential
Where you place your Devialet Phantom Ultimate speaker can make all the difference. Position between 45 and 90 cm off the ground to maximise impact. Leave at least 30 cm between the speaker and the wall, allowing bass frequencies to reflect naturally and enhance depth. Keep the area in front of your speaker(s) clear to ensure unobstructed sound propagation. For optimal listening, place the speaker between 1.5 and 2.5 metres from your seating area. In a stereo set-up, position both speakers 1.5 to 2.5 metres apart and angle them 25 to 30° inward to create a vivid, true-to-life soundstage.
Music That Moves You, At The Touch of a Button
Devialet Phantom Ultimate 98 dB comes complete with four intuitive touch controls for a tactile and intuitive listening experience: volume up, volume down, play/pause, and Bluetooth®. And an LED light on its top indicates your speaker’s status: off, booting (flashing), and on (solid white).
