Devialet Phantom Ultimate 98 dB: The Evolution of the Revolution

News / 07.10.25

When Devialet launched the original Phantom in 2015, it didn’t just introduce another wireless speaker; it reshaped the high-end audio landscape. Compact yet astonishingly powerful, the Phantom was a breakthrough in acoustic engineering. Today, the Phantom Ultimate 98 dB builds on that legacy, fusing advanced technology with precision craftsmanship to deliver a truly immersive listening experience.


A Legacy of Disruption

Devialet has always challenged audio conventions. The original Phantom redefined what was possible in a compact speaker, proving that size does not dictate performance. The Phantom Ultimate 98 dB takes this disruptive approach to the next level, refining every element to produce sound that is both powerful and pristine.


Signature Sound in a Compact Form

Despite its compact dimensions, just 157mm wide, 219mm deep, and 168mm high, the Phantom Ultimate 98 dB houses 400 W of amplification power and delivers a maximum acoustic pressure of 98 dB SPL at 1 meter. 


With a frequency response of 18 Hz to 25 kHz, the speaker captures the entire sonic spectrum. From deep bass to crystalline highs, it brings music to life in a way that engages not only the ears but the entire body.

The Phantom Ultimate 98 dB embodies Devialet’s relentless pursuit of acoustic perfection through its proprietary technologies:


  • ADH (Analogue Digital Hybrid)
  • HBI (Heart Bass Implosion)
  • SAM (Speaker Active Matching)
  • AVL (Adaptive Volume Level)


Seamless Listening Your Way

Powered by a quad-core NXP i.MX 8M Nano processor and running on Devialet’s DOS 3 operating system, the Phantom Ultimate 98 dB offers a smooth, responsive experience across all sources.


Connectivity and Streaming

  • AirPlay, Google Cast, Spotify Connect, Tidal Connect, UPnP, and Roon Ready (RAAT)
  • Bluetooth 5.2 with SBC and AAC codecs
  • Wi-Fi 5 (802.11 a/b/g/n/ac 2x2 MIMO) and Ethernet (100/1000 Mbps)
  • 1x mini-TOSLINK optical input
  • Devialet DOS 3 synchronisation protocol (96 kHz/24-bit) for seamless stereo pairing


The Devialet app enhances the experience further, offering a six-band equaliser, dedicated listening modes for Music, Movies, and Podcasts, as well as additional tools such as Bass Reducer, Loudness Compensation, and Adaptive Volume Level.


Crafted in France, Timeless Design

True to its roots, the Phantom Ultimate 98 dB is designed in Paris and assembled in Devialet’s dedicated French facility. Its sculpted form is as purposeful as it is beautiful, with a reinforced enclosure that minimises distortion and ensures consistent performance even under demanding conditions.


The speaker is available in three elegant finishes: Light Pearl, Deep Forest, and the luxurious Opera de Paris edition. Each reflects the blend of innovation and craftsmanship that defines the Phantom line.
