ADH Amplification – The Core of the Phantom Ultimate 98 dB & 108 dB

Both models rely on Devialet’s proprietary Analog Digital Hybrid (ADH) technology, which blends the sonic purity of a Class A analog amplifier with the efficiency of a digital Class D module. This ensures distortion-free, highly accurate sound reproduction even at high volumes.

Complementary features include Speaker Active Matching (SAM) for precise driver calibration, Adaptive Volume Level (AVL) for consistent dynamics, and Heart Bass Implosion (HBI) technology for powerful bass extension down to the lowest frequencies.

A new NXP i.MX 8M Nano processor provides enhanced processing efficiency, while Devialet OS (DOS3) – first seen in the Astra – serves as the modern software platform.

Differences Between Phantom Ultimate 98 dB and Phantom Ultimate 108 dB

The main distinction lies in output and frequency range:

• Phantom Ultimate 98 dB reaches a maximum of 98 dB with a frequency response from 18 Hz to 25 kHz. Ideal for smaller and medium-sized rooms where balance and detail matter.
• Phantom Ultimate 108 dB pushes output up to 108 dB, extending from 14 Hz to 35 kHz, offering a scale and presence typically associated with full-size Hi-Fi systems.

Streaming & Connectivity

The speakers are equipped with Wi-Fi 6 and Bluetooth 5.3 for reliable, future-proof wireless connections, plus an Ethernet RJ45 port for wired networking. High-resolution audio up to 24-bit/96 kHz is supported.

Touch-sensitive controls and LED indicators on the device itself provide quick access to essential functions.

Design & Craftsmanship – French Elegance

The speakers maintain Devialet’s iconic oval Phantom silhouette, refined with premium materials and subtle details. Despite their immense power reserves, both models present themselves as sculptural lifestyle products that complement luxury interiors.

Design finishes include Deep Forest and Light Pearl, while the exclusive Opéra de Paris Edition, finished in 22-carat gold leaf by Ateliers Gohard, provides an additional level of luxury.

“Devialet is more ambitious than ever. With Phantom Ultimate, we reaffirm our pioneering role in the audio industry. This new era invites listeners to experience sound with unmatched intensity, clarity, and depth – a testament to our technical excellence and savoir-faire.”
