Striking Immersive. Surprisingly Slim

Devialet Dione embodies the brand’s vision: to elevate sound to its rightful place in people’s lives. With this first all-in-one Dolby Atmos® 5.1.2 soundbar, the audio technology company provides listeners with the sound experience their home-entertainment deserve.

Devialet Dione sees the company apply its audio engineering expertise to home cinema. With a radical size- to-performance ratio and zero compromise on sound quality and immersion, Devialet brings new standard to cinematic experience in a single high-end device.

At Devialet, we thrive on creating extraordinary products that deliver unprecedented sound experiences. We have pursued our vision of redefining the place sound holds in people’s lives through our unique amplifiers, Phantom speakers, and true wireless earbuds. Now, Devialet Dione, our first soundbar, brings us even closer to our goal.” by FRANCK LEBOUCHARD, CEO OF DEVIALET


Devialet Dione features the brand’s next-generation audio processing chip: the Devialet Intelligence Processor. It combines Devialet’s amplification performance and signal processing technologies (ADH®, SAM®, Magic Wire, Class A, Digital to Analog convertor DAC, and more) into a single, one- square-centimeter System on a Chip (SoC), custom-designed for optimal efficiency and audio capabilities.

Devialet Dione combines seventeen custom-build autonomous high-end drivers powered by the proprietary Devialet technologies above, including eight internal high- excursion subwoofers in a SAM®-powered push-push configuration. Not only does this set-up eliminate the need for a separate subwoofer, but it also makes Devialet Dione capable of delivering powerful, deep, low-frequencies with improved directivity.


Using specific acoustic architecture and proprietary technologies, Devialet Dione intelligently adapts to its surroundings to provide the best experience, whatever the content or location of the unit in the room.

Thanks to beamforming techniques that cancel noise and improve spatialization, the nine high-excursion full-range speakers provide full immersion capabilities, while the eight long throw subwoofers recreate deep bass whatever the volume for a truly cinematic experience.

Devialet Dione is compatible with Dolby Atmos, offering the latest innovations in multichannel and object-based audio. The soundbar is also capable of enhancing immersion on any content such as TV channels thanks to SPACETM, the company’s proprietary 3D upmixing sound algorithm. SPACETM is turned on by default with video content and deactivated for music, with everything customizable via the Devialet app.

Adding ADE® technology, immersion remains perfect whether Dione is wall-mounted or placed flat on a piece of furniture. The internal gyroscope automatically detects its position and adjusts the audio signal accordingly, maximizing impact and immersion.


With best-in-class performance-to-thinness ratio, Devialet Dione stands out in sound quality, as well as in design.

Devialet Dione is made of premium materials and finishings, including anodized aluminium central core and carefully selected acoustic fabrics to align with high-end audio positioning. The packaging has been purposefully designed to be fully recyclable.

The sleek central ORB® is a nod to Phantom’s signature aesthetic and most importantly maintains perfect front-facing orientation no matter the position of Devialet Dione.

As Devialet Dione can be settled in 2 positions: mounted on a wall or placed flat on a piece of furniture.


Devialet Dione’s design prowess extends beyond its visual impact. It also offers a minimalist, intuitive user interface: the Devialet App. Here you can model your room using room calibration, adjust modes, and enable connection via bluetooth.

The soundbar features 4 unique audio modes: Movie and Spatial (5.1.2 upmixing), Music (true stereo rendering), and Voice (medium frequencies highlighting), tailored to different content types and usage.

For comfortable listening and a better user experience, Devialet AVLTM is embedded in the product, while the TV remote can also be used to change the volume on Devialet Dione.
