Devialet, the iconic French audio innovator, expands its wireless speaker empire with the Phantom Ultimate Speaker collection, joining a lineup that includes the flashy Mania, the refined Astra and Astra Opera de Paris integrated amplifiers, and the Dione soundbar. The new Ultimate series delivers next-generation ADH New Gen amplification, offering fully immersive sound in two models — the flagship 108 dB ($3,800) and compact 98 dB ($1,900) — in three striking finishes, cementing Devialet’s reputation for cutting-edge design and high-end audio performance.
Devialet Phantom Ultimate: Fifteen Years of French Audio Mastery, Now with Gold Detailing
Headquartered in Paris and turning heads since 2007, Devialet’s engineers have spent over fifteen years pushing sound into places most mere mortals didn’t even know existed.
With more than 250 patents covering acoustic engineering, electronics, signal processing, mechanics, and cutting-edge manufacturing, Devialet isn’t just making speakers—they’re crafting experiences. Every innovation, every iconic curve, every gleaming finish is designed to deliver listening moments that feel like nothing else on the planet—and that’s just the flagship store in Paris.
Jacques Demont, Devialet’s CEO, puts it bluntly: “We are reaffirming our status as a luxury pioneer in audio with this new launch. We invite listeners to experience sound with unprecedented intensity, clarity, and depth, coupled with our visionary approach to design.” Translation: French audio doesn’t do subtle.
The Phantom Ultimate collection comes in two models, the 108dB flagship and the more compact 98dB, both dressed to impress. You can choose from Deep Forest, a dark green with black chrome accents, or Light Pearl, an ultra-matte off-white for when you want your speaker to whisper sophistication.
For those who prefer their audio with a touch of pure decadence, the Opéra de Paris Edition ups the ante with hand-applied 22-karat gold detailing—because why not? French flair never bothers with understatement.
Devialet Phantom Ultimate: Proprietary Technologies That Redefine Sound
At the core of the Phantom Ultimate collection are the bold, proprietary technologies that have cemented Devialet’s reputation for world-class acoustic wizardry. Each one is designed to push performance while keeping a wink of French bravado intact.
ADH New Gen (Analog Digital Hybrid) – The latest incarnation of Devialet’s signature ADH tech marries the linear finesse of analog Class A amplification with the brute efficiency of digital Class D. Thanks to a smarter control algorithm, the Phantom Ultimate 108dB reaches astonishingly precise highs up to 35 kHz, while energy management and thermal dissipation are dialed in to wring every ounce of performance from the amplification.
SAM (Speaker Active Matching) – SAM is the bodyguard your speakers never knew they needed. This real-time algorithm protects the drivers while reproducing phase and amplitude with surgical accuracy, letting the Phantom Ultimate sound exactly like it should—no compromises, no apologies.
HBI (Heart Bass Implosion) – Ultra-low frequencies, compact form factor, seismic impact. HBI lets these speakers hit down to 14 Hz, delivering bass you don’t just hear—you feel it in your bones. French flair for drama meets hardcore physics—and watching those woofers flex is something you don’t forget.
AVL (Adaptive Volume Level) – Borrowed from the Dione soundbar, AVL adjusts volume dynamically depending on the content, so explosions, whispers, and movie scores hit the right intensity without constant finger-fiddling. Cinema-grade audio, minus the pretension.
New Intelligent Processor – The Phantom Ultimate packs an NXP i.MX 8M Nano SoC, a powerhouse for advanced audio processing with improved energy efficiency and optimized performance. In other words, brains as sharp as the speakers are pretty.
Together, these technologies create an experience audiophiles describe as finally “hearing music”—and yes, it sounds every bit as dramatic and precise as only the French can deliver.
Devialet Phantom Ultimate 108 dB: Flagship Performance Meets French Flair
The Phantom Ultimate 108 dB ($3,800) is Devialet’s most advanced loudspeaker to date, backed by four newly registered patents that ensure sound reproduction with razor-sharp precision, free from distortion, saturation, or background noise. Its bass drivers are optimized for smooth, controlled low frequencies that hit deep without overwhelming, while the midrange driver is engineered to eliminate unwanted resonance, keeping vocals and instruments natural and clear. The tweeter has been completely redesigned to combine mechanical robustness with refined high-frequency reproduction.
With 32-bit / 96 kHz audio processing, the Phantom Ultimate 108 dB covers an impressive frequency range from 14 Hz to 35 kHz (+/- 6 dB) and delivers a total amplification power of 1,100 W, effectively turning a single speaker into a mini orchestra. The top-mounted user interface features four intuitive touch controls, making operation straightforward and tactile. Powered by Devialet’s DOS3 software architecture, the 108 dB model supports a wide range of streaming protocols along with WiFi 6 and Bluetooth 5.3, ensuring seamless connectivity for even the most demanding audiophiles.
In short, the Phantom Ultimate 108 dB combines raw power, exceptional precision, and next-generation connectivity, all wrapped in a design that boldly embraces both elegance and aggressive French flair.
Devialet Phantom Ultimate 98 dB: Compact Power, Full-Fidelity Sound
The Phantom Ultimate 98 dB ($1,900) delivers high-fidelity sound in an ultra-compact package, proving that great things can come in small, stylish French packages. Despite its size, it offers a wide frequency response from 18 Hz to 25 kHz (+/- 6 dB), giving you deep bass and sparkling highs in a perfectly balanced mix. The speaker packs 400 W of amplification and features an optimized 32-bit / 96 kHz signal processing chain, ensuring playback is ultra-precise and true to the artist’s original intent.
Its co-spherical wideband driver design expands the soundstage, making every note and instrument feel larger than life. The Phantom Ultimate 98 dB is also flexible in setup, available in solo, stereo, or multi-room configurations via AirPlay, Google Cast, and Roon Ready, letting it fit seamlessly into any listening environment. In short, this compact powerhouse delivers remarkable precision and immersive sound without demanding a throne in your living room.
Devialet Phantom Ultimate | Opéra de Paris: A Touch of French Gold
Continuing a partnership first established in 2017 with the Opéra national de Paris, the Phantom Ultimate | Opéra de Paris editions bring a literal touch of luxury to high-end audio. Each speaker features 22-carat gold hand-applied by master gilders at Ateliers Gohard, the historic Parisian workshop behind the restoration of the Palais Garnier.
This collaboration, rooted in a shared commitment to quality and France’s cultural heritage, also helps support artistic creation at one of the country’s most prestigious institutions. The 108 dB Opéra edition retails for $4,300, while the 98 dB Opéra edition is priced at $2,400—because, naturally, gold isn’t cheap.
Seamless Connectivity & Personalization

The Bottom Line
The Phantom Ultimate 98 dB and 108 dB show just how far Devialet has come since the first generation of these speakers. Back then, they were visually striking, capable of impressively powerful bass, and technologically ahead of the curve—but a little thin on overall tonal richness.
Fast forward to today, and with the new ADH New Gen, SAM, HBI, AVL, and the intelligent processor, these speakers finally deliver the refinement their pedigree promised. Full-range, extended highs, and bass that hits deep without flabbiness—they’ve smoothed out the edges while keeping that signature French audacity.
We’d strongly advise pairing them with Devialet Treepod stands for optimal performance; these aren’t the kind of speakers you just drop on a shelf. From our experience with the Astra—one of the best amplifiers available, period—and the Mania, which stunned us even at a price above most rivals, it’s clear that this new iteration is a league of its own.
Expect sound that’s immersive, precise, and utterly attention-grabbing. Your friends and dinner guests will be wondering when you suddenly became a person of refined taste, even if they’ve never had the pleasure of a proper baguette in Paris.
