Built-in ADH (Analog Digital Hybrid) amplification pairs the linearity of Class A with the power and efficiency of Class D, and it works alongside an onboard DAC, preamp and network streamer. There is no separate amplifier, DAC or source to buy: connect it to your Wi-Fi, pick a source and it plays.Engineering is central to the Phantom's character. A sealed, pressurized cabinet houses a front aluminum-dome driver and twin lateral aluminum bass drivers that use Devialet's Heart Bass Implosion (HBI), a design that extracts deep, physical low end from a body far smaller than the sound suggests. Frequency response reaches from about 18Hz to 25kHz, and Devialet's SAM (Speaker Active Matching) tailors the output so the drivers track the source signal with precision. The Ultimate finish is a premium matte treatment that suits a serious listening space.This model is for listeners who want reference-minded sound without racks of separate components. Use one Phantom as a mono speaker, pair two for true stereo, or add units in other rooms and group them in the Devialet app for whole-home playback. It is an ideal fit for a bedroom, study, main living space or a design-forward setup where a compact footprint and clean streaming matter.Key Features Fully active wireless speaker with built-in ADH (Analog Digital Hybrid) amplification, so no separate amplifier is needed Up to 98dB SPL at 1m from a compact, self-contained enclosure Sealed, pressurized cabinet with a front aluminum-dome driver and twin lateral aluminum bass drivers Heart Bass Implosion (HBI) delivers deep, physical bass from a small body Speaker Active Matching (SAM) tunes driver output to the source signal Frequency response of about 18Hz to 25kHz Wi-Fi streaming with AirPlay 2, Spotify Connect, Roon Ready and UPnP, plus Bluetooth and an optical/analog input Run as a mono speaker, pair two for stereo, or group multiple units for multiroom in the Devialet app Premium matte Ultimate finish How the Phantom 98dB ComparesDevialet Phantom Ultimate 98dB vs Devialet Phantom Ultimate 108dBThe Phantom Ultimate 108dB is the higher model in the range and delivers greater output, reaching up to 108dB SPL with 1100W RMS and extended low end down to about 14Hz. It also steps up to a Grade 1 titanium tweeter for even more headroom. Choose the 98dB when you want the same Phantom character in a slightly more modest output class, and step up to the 108dB when you need to fill larger rooms or want the deepest reach and the highest peaks. See the Devialet Phantom Ultimate 108dB.Devialet Phantom Ultimate 98dB vs Klipsch The Nines IIThe Klipsch The Nines II is a two-piece powered stereo pair with a horn-loaded, dynamic Heritage voice and a wide set of wired inputs for turntables, TVs and consoles. The Phantom Ultimate 98dB takes a different path as a single sealed enclosure built around HBI bass, SAM tuning and app-driven streaming and multiroom. Pick the Klipsch for a traditional stereo desktop or bookshelf setup with a lively, forward character, and the Phantom for a compact, streaming-first system that can start as one speaker and grow into a pair or a whole home.
