The Devialet Dione looks unique with its spherical center speaker while the Sonos Arc has a more standard design.

The Devialet Dione (above) will take up more space than the Sonos Arc (bottom) on your TV rack due to its bigger overall design.

Both of these soundbars will take up a lot of space on your TV rack, but the Devialet Dione will take more since it is the bigger of the two. It measures 47 x 3 x 6.5 inches. Compared to that, the Sonos Arc measures 45 x 3.4 x 4.5 inches, so it’s shorter and not as wide. The Devialet Dione is also heavier, weighing 26.46 lbs. That’s double the weight of the Sonos Arc at 13.78 lbs. These soundbars are built to fit between the legs of a 65-inch TV, but they can also be wall mounted if that’s what you prefer.

When it comes to build quality, the two soundbars are excellent. The Devialet Dione is made of mostly plastic with tight fabrics that cover and protect the speakers. The sphere or orb is also made of plastic but it feels sturdy and it’s not loose. Similarly, the Sonos Arc is also made of plastic—both the body and the grilles. Both soundbars feel sturdy, but the Devialet Dione, due to its weight, feels more premium.

At the back, the Devialet Dione has an HDMI (eARC) port, an optical input and an ethernet port. On the other hand, the Sonos Arc only has an HDMI (eARC) port and an ethernet port. It does come with an HDMI to optical adapter if your TV doesn’t have enough HDMI ports available. You can get the Devialet Dione in matte black while the Sonos Arc is available in black or white.


The Devialet Dione has more features, but the Sonos Arc supports more audio formats.

Both can be wall mounted for a more streamlined look.

The most notable feature of the Devialet Dione is the spherical speaker in the center. It rotates so that it will always be in the right orientation if you decide to place the soundbar on a TV rack or wall mount it. With the soundbar’s built-in gyroscope, it can adjust the sound output of the other drivers. In addition to that spherical center speaker, the Devialet Dione also comes with the SPACE system which is basically a virtual surround sound feature. It allows the soundbar to upscale the source to take advantage of its 5.1.2 channel setup.

The apps that come with the Devialet Dione and Sonos Arc also act as their remote controllers since they don’t come with a physical one. You can access all their controls and features inside their respective apps. The Devialet app gives you access to preset EQs, control the volume and stream music via Bluetooth and WiFi. It also supports Apple Airplay2 and Spotify Connect.

The Sonos S2 app gives you access to more features such as Trueplay Room Correction (iOS only), treble and bass adjustments, sound modes and streaming via WiFi, Apple Airplay2 and Spotify Connect. The Sonos Arc does not have Bluetooth, though, so it’s a bit limited in the connectivity department.

When it comes to supported audio formats, the only difference between the two is the Sonos Arc’s support for DTS content. They both support Dolby Atmos, Dolby Digital, Dolby Digital Plus, Dolby TrueHD and 5.1 PCM.


The Devialet Dione sounds a bit better than the Sonos Arc, but the latter’s sound can be improved by adding a dedicated sub and rear speakers.

The most eye-catching feature of the Devialet Dione is its spherical speaker at the center of the soundbar.

The Devialet Dione is a 5.1.2 channel soundbar that’s designed as an all-in-one soundbar solution. It has a built-in subwoofer and side-firing speakers for phantom surrounds. The built-in subwoofer is decent, but it pales in comparison to a dedicated sub in terms of impact and sound quality. As it is a single-unit soundbar, you don’t have the option of connecting a subwoofer or satellites to improve its performance. Meanwhile, the Sonos Arc is a 5.0.2 channel soundbar with side-firing speakers for surround effects. Unlike with the Dione, you can connect a dedicated subwoofer and satellite speakers to the Sonos Arc, which will improve its performance greatly.

Out of the box, the Devialet Dione produces a more room-filling sound than the Sonos Arc due to having a built-in subwoofer. The subwoofer provides decent impact and rumble, while the mids and treble are balanced. You can listen to all types of genres with this soundbar. On the other hand, the Sonos Arc has a bright sound signature that emphasizes the highs. The mids are balanced but since it doesn’t have a built-in subwoofer, it struggles when it comes to the bass range. This will change if you opt to get the Sonos Sub as that will improve its bass reproduction significantly.

When watching movies, the two have their strengths and weaknesses. The Devialet Dione has a more complete sound, but the center channel has a bassy output that produces a muddy sound that can be hard to hear. On the other hand, the Sonos Arc’s center channel outputs a clearer sound, making dialogue easy to understand, but it doesn’t have the same low frequency impact as the Devialet Dione.


You get way more value with the Sonos Arc than the Devialet Dione.
