Some speakers are bought for how they sound. Others for how they look. The Devialet Phantom Ultimate 98 dB is one of the rare products that asks you to choose neither. It is a sculptural French design object that happens to produce bass most tower speakers would struggle with, from a body only 16.8 cm tall.
At 8mm, we have demonstrated Devialet to hundreds of listeners in our Raipur experience centre, and the reaction to the Phantom is almost always the same: people look around the room for the subwoofer. There isn’t one. In this guide we cover the Devialet Phantom Ultimate price in India, what has changed from the previous generation, how it actually sounds, how to set it up, and whether the 98 dB or the bigger 108 dB is right for your room.

What Is the Devialet Phantom Ultimate?
The Phantom Ultimate is the latest generation of Devialet’s iconic Phantom wireless speaker, the successor to the Phantom II line. It comes in two sizes: the ultra-compact 98 dB reviewed here, and the larger 108 dB flagship. Both share the same new processing platform, an NXP iMX8 chip running Devialet Operating System 3 (DOS3), which makes the speaker faster to respond, more stable when streaming and ready for future software updates.
Designed and manufactured in France, the Phantom Ultimate is sold in three finishes: Deep Forest (a rich, organic take on black), Light Pearl (a soft, matte ceramic-white) and the collectable Opéra de Paris edition, whose gold-leaf side plates are hand-applied by Ateliers Gohard, the same artisans who restore the gilding of the Palais Garnier.

How Does the Devialet Phantom Ultimate Sound?
Bass that defies the size
The headline number is 18Hz. That is deeper than many full-size floorstanding speakers, and it comes from Devialet’s patented HBI® (Heart Bass Implosion) design, where two side-firing woofers move in opposition inside a sealed enclosure. The forces cancel each other, so the speaker does not rattle or walk across the table, while the air pressure it creates is something you feel in your chest. On tracks with real low-end content, like film scores or electronic music, the Phantom Ultimate 98 dB produces bass that is deep, tight and controlled rather than boomy.
Clarity without distortion
ADH® (Analog Digital Hybrid) amplification combines the finesse of Class A with the efficiency of Class D. The new generation adds predictive control that anticipates the drivers’ behaviour in real time. In practical terms, vocals stay clean and instruments keep their separation even as you push the volume, which is exactly where most compact wireless speakers fall apart.
Studio-grade accuracy
SAM® (Speaker Active Matching) tunes the amplifier to the exact physical behaviour of the drivers, so the speaker plays what was recorded rather than an exaggerated version of it. Through the Devialet app you can choose a fuller default voicing, a flatter Monitoring mode for critical listening, or Night Mode, which reins in the bass and evens out volume swings for late-night movies.
Room-filling dispersion
The spherical, co-axial shape radiates sound evenly around the room, so there is no narrow “sweet spot”. For a bedroom, study, cabin or apartment living room, a single Phantom Ultimate 98 dB is genuinely enough.
Connectivity: Stream Your Way
The Phantom Ultimate is a true smart wireless speaker with every major streaming standard built in. iPhone users get AirPlay 2, Android users get Google Cast, and anyone can connect over Bluetooth. Serious listeners can use Spotify Connect, TIDAL Connect and Roon Ready for high-resolution playback, and UPnP for music stored on a NAS. A wired Ethernet port is available for rock-solid streaming, and an optical input lets you connect it straight to a TV.
Stereo Pair, Multiroom and TV Setup
Pair two units and the Phantom Ultimate 98 dB becomes a proper stereo system rated at 101 dB SPL, with a wide soundstage and precise imaging. Note that only two speakers of the same model can be paired in stereo, so a 98 dB cannot be paired with a 108 dB.
A stereo pair connected via optical makes an elegant, minimal TV and music system. For full surround and Dolby Atmos in a dedicated media room, we usually recommend a proper home theater setup or a premium soundbar instead, and our team can help you decide.
The 98 dB works with Devialet’s Tree floor stand, Gecko wall mount and the Devialet Remote. It does not support the Devialet Arch, but accessories from the older Phantom II range, including the Cocoon carry case, are compatible.
Placement Tips From Our Installation Team
After more than 800 installations, these are the settings that make the biggest difference:
• Height: place the speaker between 45 and 90 cm off the floor. A sideboard or the Tree stand is ideal.
• Wall distance: leave at least 30 cm behind the speaker so the bass can develop naturally.
• Listening distance: sit roughly 1.5 to 2.5 metres away.
• Clear line: keep the area in front of the speaker free of obstructions.
• Use the app: if the bass feels heavy in a small room, try Monitoring mode or adjust the bass balance.

Choose the 98 dB if your room is small to medium, you value a discreet footprint, or you plan to buy a stereo pair. Choose the 108 dB if you have a large, open space or want concert-level volume from a single speaker. Browse the complete Devialet range at 8mm to compare.
Is the Devialet Phantom Ultimate 98 dB Worth Buying?
Buy it if you want a single, beautiful speaker that replaces an entire hi-fi stack, you listen to a lot of bass-rich music, you appreciate design as much as sound, or you want a compact stereo pair for music and TV.
Look elsewhere if you need Dolby Atmos surround for movies, you need a portable battery speaker, or your budget is better suited to a conventional pair of powered speakers.
For the listener who wants the most sound per square centimetre available today, the Devialet Phantom Ultimate 98 dB is in a class of its own.
