There's a category of speaker that doesn't fit neatly into home theater speaker or portable speaker — it's simply a piece of French engineering that happens to sound like a full-size hi-fi system. That's the Devialet Phantom Ultimate 98dB, India's most powerful ultra-compact wireless speaker, and quite possibly the boldest-looking speaker you'll ever put in a living room.
At 8mm, we get one question about this speaker more than any other: "Is it really worth it?" This guide covers the Devialet Phantom Ultimate 98dB's price in India, full specifications, sound signature, setup, and who this speaker is actually built for — so you can decide with confidence.
What Is the Devialet Phantom Ultimate 98dB?
The Devialet Phantom Ultimate 98dB is a compact, spherical, all-in-one wireless speaker from Devialet — the same French audio house known for its reference-grade amplifiers. It's an evolution of the original Phantom line first launched in 2015, now rebuilt with a cleaner cabinet, a reimagined grille, and improved internal drivers. Weighing just 4.3kg and fitting easily on a shelf or console, it's designed to deliver full-room, high-fidelity sound without the footprint of a traditional speaker system.
It's sold at 8mm in three finishes — Deep Forest, Light Pearl, and the limited Opéra de Paris edition, created in partnership with the Opéra national de Paris — each available on the Devialet Phantom Ultimate 98dB product page.

Sound Quality: What Makes It Different
The headline spec on the Devialet Phantom Ultimate 98dB isn't loudness — it's control. ADH® amplification blends the warmth of Class-A analog with the efficiency of Class-D digital, which is why the speaker manages to sound both powerful and clean at the same time, with none of the distortion or harshness you'd expect from a speaker this compact pushed this hard.
HBI® is what really surprises first-time listeners — infrabass reaching down to around 18Hz from a speaker that fits in one hand. SAM® continuously adjusts the amplification in real time to match the exact acoustic signature of the drivers, so bass stays tight instead of boomy even at higher volumes. For movies, this makes the Devialet Phantom Ultimate a genuinely capable stand-in for a small home theater setup — though for full surround and Dolby Atmos, we'd still point serious movie watchers toward a proper soundbar or AV receiver-based system.
Setup, App Control & Stereo Pairing
Setup happens entirely through the Devialet app (iOS and Android), which is required even for first-time Bluetooth use. Once configured, the app unlocks a 6-band EQ, dedicated Music, Movie, and Podcast modes, a Bass Reducer, Loudness, and Night Mode. If you own two Devialet Phantom Ultimate 98dB units, the app will automatically prompt stereo pairing — giving you true left-right separation instead of a single mono source. For placement, Devialet recommends positioning the speaker 45–90cm off the ground, at least 30cm from the nearest wall, and 1.5–2.5m from your listening position for the most accurate soundstage.
Who Should Buy the Devialet Phantom Ultimate 98dB?
• Apartment and medium-room listeners who want reference-quality sound without visible cabling or bulky towers
• Design-conscious buyers who want a speaker that looks as considered as it sounds
• Streamers on Spotify, TIDAL, Qobuz, or Roon who want a true high-resolution wireless endpoint
• Anyone deciding between the 98dB and 108dB Phantom Ultimate — the 98dB suits apartments and mid-sized rooms, while the 108dB is built for larger spaces needing higher peak output
