Devialet Phantom Ultimate Refresh: Updated Design, Power & Streaming

By: Dipin Sehdev

Devialet has long occupied a unique space in high-end audio. Since the first Phantom speaker launched in 2015, the French company has positioned itself as a design-forward, technology-driven brand offering luxury wireless speakers that double as conversation pieces. Over the years, the Phantom has built a reputation for deep bass, distinctive styling, and proprietary amplification technologies that set it apart from more traditional hi-fi systems.

With the Phantom Ultimate series, Devialet isn’t rewriting the playbook—it’s updating it. The two new models, the Phantom Ultimate 98 dB ($1,900) and the Phantom Ultimate 108 dB ($3,800), retain the brand’s signature look while incorporating refined amplification, updated processing, and better connectivity. This isn’t a radical departure—it’s a much-needed refresh that modernizes the Phantom line for today’s streaming and multi-room environments.

Evolution, Not Reinvention

For many listeners, the original Phantom was striking but polarizing. It impressed with its low-frequency output and bold design but could feel slightly uneven in tonal balance and lacked the broader platform support that’s now standard in premium wireless speakers.

The Phantom Ultimate addresses those shortcomings by introducing ADH New Gen amplification, improved DSP via a new intelligent processor, and expanded streaming options. Both models support AirPlay, Google Cast, Spotify Connect, TIDAL Connect, Roon Ready, and UPnP, making them more versatile in modern ecosystems. Connectivity has also been upgraded with Wi-Fi 6 and Bluetooth 5.3.

The design has seen subtle refinements rather than a full overhaul. The original woofer cover is gone, and a new tweeter grille has been developed to improve acoustic performance. These changes bring the Phantom line closer to current expectations while maintaining the recognizable sculptural profile.

Proprietary Technologies, Updated

Devialet continues to rely on its suite of proprietary technologies, with updates that bring improved performance and efficiency:

  • ADH New Gen (Analog Digital Hybrid): Combines the smoothness of Class A amplification with the efficiency of Class D, now with refined algorithms for better energy and thermal management.

  • SAM (Speaker Active Matching): Real-time driver monitoring ensures accurate reproduction and protects the hardware.

  • HBI (Heart Bass Implosion): Extends bass response well below typical wireless speakers, down to 14 Hz in the flagship model.

  • AVL (Adaptive Volume Level): Adjusts loudness depending on content, borrowed from Devialet’s Dione soundbar.

  • Intelligent Processor (NXP i.MX 8M Nano): Provides the computing power for advanced DSP and energy efficiency.

These aren’t new ideas but refinements of the technologies that have defined Devialet’s products for the last decade.

Model Breakdown

Phantom Ultimate 108 dB ($3,800)

The 108 dB is the flagship of the line, intended for listeners who want maximum performance from a single wireless speaker.

  • Amplification: 1,100 W

  • Frequency Response: 14 Hz – 35 kHz (+/- 6 dB)

  • Processing: 32-bit / 96 kHz

  • Connectivity: Wi-Fi 6, Bluetooth 5.3, AirPlay, Google Cast, Roon Ready, Spotify/TIDAL Connect, UPnP

  • Finishes: Deep Forest, Light Pearl, or Opéra de Paris edition ($4,300) with 22K gold accents

This model is about refinement. Bass is better controlled, highs extend further, and the design has been optimized to reduce distortion and resonance. It’s a capable all-in-one speaker but priced firmly in the luxury bracket.

Phantom Ultimate 98 dB ($1,900)

The 98 dB is the more compact and accessible option.

  • Amplification: 400 W

  • Frequency Response: 18 Hz – 25 kHz (+/- 6 dB)

  • Processing: 32-bit / 96 kHz

  • Connectivity: Same as the 108 dB

  • Finishes: Deep Forest, Light Pearl, or Opéra de Paris edition ($2,400)

While it lacks the sheer power and extension of the flagship, it delivers strong performance for its size and integrates more easily into smaller rooms or multi-room setups.

Accessories

Devialet offers a range of stands, mounts, and cases designed to complement the Phantom Ultimate:

  • Tree Stand ($299) – Raises the 98 dB to listening height.

  • Treepod Stand ($349) – A premium tripod stand for the 108 dB.

  • Cocoon Case ($299) – A travel case for the 98 dB.

  • Gecko Wall Mount ($299) – Discreet wall mounting solution.

  • Remote ($199) – Aluminum remote for precise control.

These options make it easier to integrate the Phantom into different environments, though they add significantly to the overall cost.

Price & Availability

  • Phantom Ultimate 98 dB: $1,900 (available now)

  • Phantom Ultimate 108 dB: $3,800 (pre-order, shipping soon)

  • Opéra de Paris Editions: $2,400 (98 dB) / $4,300 (108 dB)

Available through Devialet stores, premium audio dealers, and online. Pricing is per speaker, meaning stereo setups are significantly more expensive than competitors priced by the pair.

How They Compare

The wireless hi-fi space has grown significantly since the first Phantom launched. Rivals like KEF, Sonus faber, and Klipsch now offer strong alternatives.

Contextual Analysis

  • Performance: Devialet still leads in bass extension and outright power, though KEF offers higher resolution playback at 384 kHz.

  • Design Philosophy: Devialet focuses on futuristic sculptural design, while KEF opts for modern minimalism, Sonus faber leans on traditional craftsmanship, and Klipsch plays up retro styling.

  • Value: Devialet’s per-speaker pricing makes stereo setups very expensive compared to KEF and Sonus faber, which sell by the pair. Klipsch offers an entry point for buyers not looking to spend four figures.

  • Market Position: The Phantom Ultimate is less about setting a new benchmark and more about keeping Devialet competitive in a category where expectations around streaming, DSP, and multi-room support have become standard.

Verdict

The Phantom Ultimate 98 dB and 108 dB don’t reinvent Devialet’s formula. Instead, they refine it. The updated amplification, processor, and connectivity options bring the line up to modern standards, while the design adjustments smooth out some of the original Phantom’s rough edges.

For existing Devialet fans, this is a welcome upgrade. For those entering the high-end wireless speaker market, it represents another strong option—though one that comes at a premium price compared to competitors.

In short, the Phantom Ultimate series is not a new benchmark. It’s a necessary evolution, ensuring Devialet’s distinctive approach remains relevant in a segment that’s grown increasingly competitive.
