W hen it comes to high-end speakers, few brands command the same level of hype and prestige as Devialet. Known for pushing the boundaries of audio engineering, the Phantom I 108dB Gold Stereo is delivering earth-shaking bass, pristine mids, and crystalline highs in a compact, futuristic form factor. But does it truly live up to its premium status?

First Impressions: Futuristic Elegance Meets Uncompromising Build Quality

With its compact, gold and matte finish design the Phantom I look like pieces of modern art rather than traditional speakers. The Phantom I is the result of over 10 years of research and development, with 100 specialists in aerodynamics, automotive, acoustics, and mechanical engineering. The result is a system capable of pushing the limits of physics, and deliver standard-setting performance. Aside from outstanding sound performances (zero distortion, zero saturation, zero background noise) and futuristic design, the Phantom I is a technical prowess. The density is astonishing-1431 parts packed in such a compact speaker with a total weight of 11.4 kg.  

Key Features:

• 108 dB SPL (Sound Pressure Level) – As loud as a live rock concert.
• 14Hz–27kHz frequency response – Deep, tight bass and sparkling treble.
• 1,100W RMS per speaker – Pure power with minimal distortion.
• ADH® (Analog Digital Hybrid) Amplification – Devialet’s proprietary technology for the best of analog warmth and digital precision.
• SAM® (Speaker Active Matching) Technology – Ensures perfect synchronization between drivers.
• HBI® (Heart Bass Implosion) Technology – The reason this speaker can hit 14Hz without a subwoofer.

Setup & Connectivity

Setting up the Phantom I Stereo system is shockingly simple. Using the Devialet app, you can pair two Phantom I units in stereo mode within minutes. The app allows you to precisely fine tune the equalizer, configure a multi-room setup and precisely control the volume.

The Phantom I offers multiple connectivity options, fulfilling any user need and preferences:

• Wi-Fi & Ethernet – For high-resolution streaming. (Ethernet is required when pairing more than 6 Phantom I)
• Bluetooth 5.0 – For quick and seamless connection.
• AirPlay 2 & Spotify Connect – Native integration through the app.
• UPnP (24-bit/96kHz support) – For audiophile-grade streaming.

The Phantom I is Roon Ready allowing you to enjoy an audiophile grade music experience out of the Box. No need to purchase the Roon Nucleus (retail price € 450.-). The included premium remote control is a nice touch, It feels as luxurious as the speakers and the tactile volume adjustments and playback control is a pleasure to use. It would have been nice to be able to switch between different equalizer settings. If you like to listen to music from different sources, just pair the Phantom I with Argon Audio SA1.

Sound Quality

The Bass are absolutely mind-blowing. The HBI® (Heart Bass Implosion) Technology allows the Phantom I to hit 14Hz, which is lower than what most subwoofers can achieve, and to deliver 60 kilos of thrust force in the lateral woofers.

The Mids & Highs are also where the Phantom I Stereo setup shines. Vocals are crisp, instruments sound natural, and treble is sharp but never harsh. Listening feels like being in a live performance.

When used in stereo mode, the Phantom I creates an incredibly wide soundstage with precise instrument separation. You can pinpoint where each element of a track is coming from.

At 108dB, these speakers are capable of filling a large room—or even an outdoor space—with powerful, distortion-free sound.

Special Edition – Opéra de Paris

If the Phantom I is not luxurious enough, you might want to get our hands on the special edition, inspired by the iconic gilded interiors of the Opéra de Paris. The master gilders at Ateliers Gohard finished the Phantom’s gold leaf side plates following time-honored methods. Each gold leaf is applied by hand to create a unique patina. And these heritage techniques demand absolute perfection—once the leaf has been applied, it cannot be removed. The side plates are gilded with Moon Gold, a precious and stainless palladium-yellow gold alloy. If this edition is still not satisfying your luxury needs, you might want get the Yang Bao & Wa Liu edition. The side panels of this Limited Edition are produced by Ateliers Gohard and undergoe a meticulous application process—from raw flange formation and polishing by Guy Degrenne, through to hand-adorment with 22.5-carat gold leaf, red varnish, and a matte finish for a whooping price of € 12’000.-

And while you are at it  you might want to grab a pair of Treepod for an additional 600.-
