Devialet Dione: untethered sound

Sound. No strings attached.

Intensely immersive

The Devialet Dione is the fruit of Devialet’s acoustic engineering applied to Home Cinema: an “all-in-one” 5.1.2-channel High End sound bar compatible with Dolby Atmos that elevates the contents of your television.

Engineering Excellence

Seventeen individual High End speakers deliver exceptionally dynamic mids and crystal-clear highs, while eight active subwoofers with SAM technology eliminate the need for additional equipment, making the DevialetDione a truly all-in-one sound bar.

Incredibly Discreet

Equipped with the best performance/thinness ratio of products in its class, the Devialet Dione excels in both design and sound quality, fading away when the action begins. And its stylized central ORB dial is a nod to the Phantom’s distinctive aesthetic.

La Devialet Dione It’s all you need.

External subwoofer? There is no need to add it since it is inside. The Devialet Dione sound bar includes eight subwoofers inside, the highest number on the market, which makes it a true all-in-one sound system.

The Devialet Dione’s 8 high-drive subwoofers are tailored to deliver powerful, deep low-frequency effects with improved sound wave directivity to substantially enhance bass reproduction and immersion.

More is more

The Devialet Dione sound bar incorporates a set of 17 High End speakers arranged in a 5.1.2 channel surround sound configuration consisting of five base channels, one subwoofer channel and two height/ceiling channels.

Equipped with more speakers than a traditional sound bar, the Devialet Dione provides sound capable of filling any room with rich bass, clear mids and precise highs. In other words, sound that immerses you in the scene.

Enjoy a sound that goes up and beyond.

The Devialet Dione sound bar supports Dolby Atmos, allowing it to provide an extraordinarily immersive 5.1.2 channel surround sound viewing experience.

SPACE technology ensures an immersive and enveloping sound experience. Powered by Devialet, it actively scales any 2.0 channel stereo signal to a 5.1.2 channel signal regardless of what you’re watching. In other words, your sight may have it right in front of you in a straight line, but its sound will surround you everywhere.

The Adaptability Gene

Cutting-edge acoustic engineering without complications. The Devialet Dione intelligently adapts to each room to provide the best experience whatever the content you are viewing.

Whether mounted on the wall or on a piece of furniture, the Devialet Dione takes advantage of its room calibration technology to fill your space with crystal-clear sound regardless of the settings, audio modes and equalization you prefer.

Devialet Intelligence Processor

The Devialet Intelligence Processor combines Devialet’s exclusive signal amplification and processing technologies (ADF, SAM, Magic Wire, Class A, DAC) in a single System on a Chip (SoC) integrated circuit custom designed for optimal efficiency.

Adaptive Volume Level

Devialet’s Adaptive Volume Level (AVL) technology is the dynamic equalizer of the Devialet Dione. Harmonizes, in real time, the sound levels adapted to each content to provide a more pleasant listening experience. An action-packed scene combined with whispered dialogue? You will not miss even the smallest detail.

Music from anywhere,whenever

The Devialet Dione is compatible with Bluetooth, AirPlay 2 and Spotify Connect. It can also be connected to your TV via HDMI or TosLink optical input for any digital music source. And when combined with SPACE technology, your favorite music is spatialized and reproduced with exceptionally immersive 3D sound.

Enjoy your favorite streaming.

Immerse yourself in your favorite movies and series from Netflix, Prime Video, Disney+ or Apple TV+ with the Devialet Dione sound bar. Thanks to SPACE technology, movies with stereophonic sound are spatialized to provide 5.1.2 channel audio and efficiently use the 3D audio capabilities of the Devialet Dione.

“Incredibly deep, immersive and impactful bass.”

The Numériques

“I’ve never heard anything that provides such a rich, full sound from a single cabinet, and I think this will convince a lot of people who get the chance to hear it.”


“We’ve been fortunate enough to hear the soundbar in action and it’s superb, with powerful bass and clear dialogue when the situation calls for it.”


Pushing the limits of sound experience

Devialet was born from a commitment: to push the limits of sound experiences. Fourteen years later, after creating revolutionary and iconoclastic innovations in the field of acoustics, Devialet ventures into the universe of audiovisuals.
