Inside its sealed shell sits 1100W RMS of built-in ADH (Analog Digital Hybrid) amplification, a combination of Class A linearity and Class D efficiency, along with a DAC, preamplifier and full streaming platform. Because everything is integrated, the Phantom needs no separate amplifier, DAC or source component.Sound is produced by a Grade 1 titanium tweeter, an aluminum medium driver and lateral aluminum bass drivers that work in opposition using Devialet's Heart Bass Implosion (HBI). This architecture lets the Phantom reach down to 14Hz and up to 108dB SPL at one meter, with deep, tactile low frequencies and no visible driver excursion beyond the pulsing side domes. The Ultimate designation adds a premium matte finish to the package.It is built for listeners who want reference-level output and full-range presence without a rack of separates. Use one as a mono speaker in a room, pair two for a wide stereo image, or add more units across the home for multiroom playback through the Devialet app. Streaming arrives over Wi-Fi with AirPlay 2, Spotify Connect, Roon Ready and UPnP, plus Bluetooth and an optical input for wired sources.Key Features 1100W RMS of built-in ADH (Analog Digital Hybrid) amplification combining Class A linearity with Class D power Up to 108dB SPL at 1m for reference-level output from a single enclosure Grade 1 titanium tweeter with aluminum medium and lateral aluminum bass drivers Heart Bass Implosion (HBI) twin lateral bass drivers for deep, tactile low end Extended frequency response from 14Hz to 27kHz SAM (Speaker Active Matching) optimizes driver behavior for accurate reproduction Wi-Fi streaming with AirPlay 2, Spotify Connect, Roon Ready and UPnP, plus Bluetooth and optical input Use solo, as a stereo pair, or grouped for multiroom via the Devialet app Premium Ultimate matte finish How the Phantom 108dB ComparesDevialet Phantom Ultimate 108dB vs Devialet Phantom Ultimate 98dBThe Phantom Ultimate 98dB is the more compact Phantom II class model, reaching up to 98dB SPL with a frequency response of about 18Hz to 25kHz. The 108dB version steps up to 1100W RMS, a Grade 1 titanium tweeter and deeper 14Hz extension for greater output and scale. Choose the 98dB for medium rooms and the 108dB when you want maximum headroom and the lowest bass reach from a single speaker. See the Devialet Phantom Ultimate 98dB.Devialet Phantom Ultimate 108dB vs Klipsch The Nines IIThe Klipsch The Nines II is a horn-loaded powered stereo pair with a lively, dynamic Heritage voicing and multiple wired and wireless inputs. The Phantom Ultimate 108dB takes a different approach as a single sealed enclosure with omnidirectional bass and streaming built in, and can be paired for stereo when desired. Pick the Klipsch for a traditional two-box stereo character, or the Phantom for a compact full-range source that starts as one unit. See the Klipsch The Nines II.Devialet Phantom Ultimate 108dB vs Cambridge Audio L/R XThe Cambridge Audio L/R X is an active stereo streaming pair designed as a discreet, integrated two-speaker system with a clean, neutral presentation.
