Description

High-End Performance in a Compact Body

The Devialet Phantom Ultimate 98 dB offers all the hallmarks of the Phantom series in a smaller and more accessible form. Delivering a maximum sound pressure level of 98 dB, it provides rich, detailed, and room-filling audio while maintaining an elegant and compact design.

Balanced Power and Precision

With 400 watts of total amplification, the Phantom Ultimate 98 dB strikes the perfect balance between power and efficiency. It ensures clean reproduction of every detail, from delicate strings to dynamic percussions, while remaining suitable for smaller spaces.

Exclusive Devialet Technologies

The Phantom Ultimate 98 dB features Devialet’s signature innovations, including ADH®, SAM®, HBI®, and Magic Wire DAC technology. These ensure pristine sound reproduction, with accurate time-domain performance and remarkably lifelike audio.

Accurate Bass Response

Thanks to SAM® control, the dual woofers deliver bass down to 18 Hz, extending well below what is expected from such a compact enclosure. The result is impactful low frequencies that retain definition and never overwhelm the music.

Heart Bass Implosion (HBI®) Compact Power

Even at this scale, HBI® technology allows the speaker to produce deep bass that feels larger than life. With its push-push woofer configuration, vibrations are canceled out, keeping the enclosure stable and distortion-free.

Full-Range Aluminum Dome Driver

Unlike the three-way system of the 108 dB version, the 98 dB model features a high-quality full-range aluminum dome driver supported by dual woofers. This configuration ensures smooth midrange and treble response for a naturally coherent sound.

Iconic Design and Premium Finishes

The compact design (157 × 168 × 219 mm) retains Phantom’s spherical identity, available in finishes such as Light Pearl, Deep Forest, and Opéra de Paris. Whether placed in a living room, office, or studio, it doubles as a striking design piece.

Modern Connectivity Options

Connectivity includes Wi-Fi 5, Bluetooth 5.2, AirPlay, Google Cast, Spotify Connect, Tidal Connect, UPnP, and Roon Ready. An optical input and Ethernet port provide additional flexibility for both digital music and home entertainment setups.

App-Driven Personalization

Through the Devialet app, users can select dedicated listening modes and access a 6-band equalizer. Features like Adaptive Volume Leveling (AVL™), Bass Reducer, and Night Mode make it easy to adapt the sound to any environment or time of day.

Efficient Power Supply

The custom Devialet PSU ensures stable power delivery while keeping standby consumption below 2 W. This efficiency makes the 98 dB version both eco-friendly and capable of sustaining high performance during extended listening.

Lightweight and Versatile

Weighing just 4.3 kg, the Phantom Ultimate 98 dB is portable yet powerful. It is ideal for those seeking audiophile performance in a compact footprint without compromising on quality or technology.

A Gateway to the Phantom Experience

The Phantom Ultimate 98 dB embodies Devialet’s vision of democratizing exceptional sound. It delivers the essence of the Phantom series—radical design, exclusive technology, and powerful performance—in a smaller, more accessible package.
