The Devialet Dione is the debut soundbar from the French manufacturer, which is best known for its line of speakers and amplifiers. It has a unique design, with a center channel 'orb' that rotates based on whether you mount the bar to the wall or set it on a TV stand to ensure clear and accurate vocals and a rich, thumpy bass regardless of its position. It's a 5.1.2 standalone bar ideal for those who don't have the space in their setup for an extra subwoofer or satellites, and its integrated subwoofers reproduce a more extended low-bass than traditional all-in-one bars. Since it's designed for use on its own, it doesn't offer any upgrades, so you can't add on separate satellites like with the Sonos Arc or the Bose Smart Soundbar 900. The lack of certain sound enhancement features or DTS:X support for those who watch a lot of Blu-rays is disappointing, especially given its premium price point.
Our Verdict
The Devialet Dione soundbar is good for mixed usage. It's a 5.1.2 soundbar with good sound quality, so you get the deep thump and rumble in the bass range, with stellar vocal clarity in the mids, so dialogue is present in the mix. There's Dolby Atmos support, too, and the bar offers an immersive listening experience, especially when you mount it to your wall. That said, there aren't many customization tools on hand, and you can't add on rears to improve its surround sound.
- Gets loud.
- Extended low-bass.
- Room correction feature.
- No bass and treble adjustments or graphic EQ.
- Middling surround sound performance.
The Devialet Dione is great for dialogue-focused TV shows and podcasts. With its balanced mids, voices are clearly and accurately reproduced in the mix, and you can even activate its 'Vocal' EQ preset to enhance the dialogue. Since there's a discrete center channel, dialogue is also quite accurately localized within the soundstage. Its latency is fairly high, so you notice some lip-synching issues when the bar is connected to your TV over Optical or HDMI.

- Dialogue enhancement feature.
- Fairly high latency.
The Devialet Dione is good for music. It has a bass-heavy sound profile that adds extra thump and rumble to the mix, so you really feel the excitement in bass-centric genres like hip-hop and EDM. Its balanced mids ensure that vocals and lead instruments are still clear and present in the mix, and higher frequencies are detailed and accurate. Since there's a room correction feature, the bar's audio reproduction calibrates based on your room's unique acoustics for the best-possible sound. That said, for such a premium bar, it's really lacking sound enhancement features, so you can't customize its sound to your liking.
- Gets loud.
- Extended low-bass.
- Room correction feature.
- No bass and treble adjustments or graphic EQ.
The Devialet Dione is decent for movies. It's a 5.1.2 bar that supports Dolby Atmos, and it gives a pretty immersive performance, especially compared to other standalone bars. You feel the thump and rumble in action-packed scenes, especially when the bar is mounted to the wall. There's also support for some common 5.1 surround sound formats, including Dolby Digital. However, the resulting performance isn't as clear and real as what you get with bars that come with discrete satellite speakers. Unfortunately, you can't add them on separately to improve its performance, either.
- Extended low-bass.
- Room correction feature.
- No DTS support.

Popular Soundbar Comparisons
The Devialet Dione is a 5.1.2 setup with a really unique design that lets you mount it to your wall or place it on a TV stand without impacting the sound quality. For a standalone bar, it does a really good job reproducing the deep thump and rumble in the low-bass and offers an immersive Atmos experience. However, it doesn't offer as many features as other top-of-the-line bars like the Bose Smart Soundbar 900 or the Sonos Arc, as there's no DTS:X support and no HDMI passthrough available. The sound enhancement features are limited, and there isn't an option to add on rears, either. Given its high-end price point, you may find more value in other premium full setups on the market, like the Samsung HW-Q990B, the Sonos Arc with Sub + One SL Speakers, or the Bose Smart Soundbar 900 with Speakers + Bass Module.

The Sonos Arc is better than the Devialet Dione for most uses. The Sonos is a 5.0.2 setup that doesn't reproduce as much low-bass as the Devialet, but its wider, more immersive soundstage makes it ideal for watching movies. It has a better surround performance and more enhancement features to help you customize its sound. There's DTS support and built-in voice assistant capabilities, which the Devialet lacks. Also, you can add on rears or a dedicated sub to improve its performance, giving you more flexibility than the Devialet.
The Sennheiser AMBEO Soundbar MAX and the Devialet Dione are both very premium standalone bars with solid performances, but the Sennheiser is better overall. The Sennheiser doesn't offer as much boom in the bass as the Devialet out-of-the-box, but since it has more sound customization tools, you can easily adjust it to get a similar sound. It has a better surrounds performance, as well as support for more audio formats like DTS. There are also three HDMI In ports for passthrough, which the Devialet lacks. It's a bit larger than the Devialet, though, which isn't ideal for everyone.
The Bose Smart Soundbar 900 with Speakers + Bass Module is better for most uses than the Devialet Dione, though they both address different types of listeners. The Bose's full setup offers premium performance with a wide, immersive soundstage and better surrounds, thanks to its included satellites. It has more sound enhancement features, like bass and treble adjustments. That said, the Devialet is a standalone bar that's suitable for Atmos if you don't want all the extra add-ons.
The Samsung HW-Q950A is better for most uses than the Devialet Dione. These bars have very different designs, as the Devialet is a standalone bar that's meant for use on its own, while the Samsung comes with satellites and a dedicated subwoofer included. The Samsung has better surround and soundstage performances, as well as more sound enhancement features to customize its sound. Unlike the Devialet, there's DTS support as well as HDMI In ports for video passthrough. It's a better value, too, but if you don't have space for all the add-ons, the standalone Devialet may be more suitable.
