The Ultimate in Home Audio Performance
The Devialet Phantom Ultimate 108 dB redefines what a single home speaker is capable of. Bolstered by three interlinked proprietary technologies, the Phantom Ultimate's Heart Bass Implosion (HBI) delivers driving, steadfast low end, while Speaker Active Matching (SAM) software adapts in real time to transients and steady-state signals, and Analog Digital Hybrid (ADH) amplification provides extended frequency response. The result is steady pitch, natural rhythms, and an enhanced soundstage across studio recordings and live performances, bringing them to life in your home with unparalleled emotion, precision, and depth. Stream your audio from your favorite high-resolution platform over Bluetooth 5.3 or Wi-Fi 6, and use the Devialet app to dial in your ideal listening settings. To pair two Phantom Ultimate 108 dB speakers in stereo, it's as simple as connecting via the Devialet app, and for multi-room functionality, the Phantom Ultimate is compatible with AirPlay, Google Cast, and Roon. Complete with a modern enclosure available in a number of elegant, organic-inspired finishes, the Devialet Phantom Ultimate 108 dB melds stunning aesthetics with cutting-edge sonic capabilities and may just be the ultimate home audio statement piece.

Proprietary Analog Digital Hybrid technology
For the Phantom Ultimate 108 dB, Devialet took a novel approach, combining a Class A amplifier with support from numerous Class D amplification stages. The resultant ADH technology provides a frequency range up to 35kHz, with crystal-clear highs and lower power consumption, even when the system is driven hard. Delivering amplification in a class all its own, the Phantom Ultimate 108 dB’s ADH technology combines analog soul with digital muscle for consistent, exceptional audio performance.


Bass that you feel
Thanks to Devialet’s HBI technology, the Phantom Ultimate 108 dB speaker reaches frequencies as low as 14Hz. Given the speaker’s compact, sealed enclosure, this level of low-end power is a truly impressive feat. HBI is the result of two dustcap-free, ABS convex woofers firing in opposing directions, generating enormous air pressure and infrasonic bass that you feel just as much as you hear. The woofers were also redesigned with an under-hung motor and low-stiffness suspension, resulting in more agile cone movement that delivers focused bass and minimal distortion even at high volume.
Natural sound across the audio spectrum
Rounding out Devialet’s trio of proprietary technologies is Speaker Active Matching (SAM). This software works behind the scenes and adapts in real-time to transient information and steady-state signals, allowing the Phantom Ultimate 108 dB to precisely adapt to the audio it's playing. The result is enhanced audio precision and consistent pitch stability, especially at lower frequencies. Rhythm sections benefit as well, and Sweetwater's home audio experts have commented that bass and drums sound bold yet natural through the Phantom Ultimate 108 dB, even during quick, complex musical passages.


Comprehensive customization via the Devialet app
Piloting this Space Age-style speaker is easy with the Devialet app for iOS and Android. After using it to set up your new Phantom Ultimate 108 dB, you’ll be able to customize numerous elements to your liking, including a 6-band EQ, a Bass Reducer, and Loudness controls for quick adjustments without needing the full EQ. Additionally, its Music, Movie, Podcast, and Night listening modes optimize the Phantom Ultimate 108 dB’s response according to your current content. However, if you want a truly frictionless listening experience, the Adaptive Volume Level (AVL) technology has you covered: it automatically applies real-time, program-dependent EQ that ensures excellent sound no matter what media you’re playing.
