Differences Between Sizes And Variants

This soundbar is available both in white and black. While we reviewed the black version, we expect this review to be valid for the white variant as well. This review is also only valid for the full setup, and not for the standalone bar.

Sonos has also released a Costco-exclusive version of this soundbar. It should perform the same, but it doesn't come with a built-in microphone.

Compared To Other Soundbars

The Sonos Arc full 5.1.2 setup is a very good overall soundbar. Thanks to its sound enhancement features, it has a very neutral, balanced sound profile and is in the same ballpark as the often-compared Samsung HW-Q90R regarding audio reproduction.

For more options, check out our recommendations for the best soundbars, the best Dolby Atmos soundbars, and the best soundbars for movies.

Samsung HW-Q990C

The Samsung HW-Q990C and the Sonos Arc with Sub + One SL Speakers are two of the top soundbars on the market, and their premium performance shines with everything from music to movies to TV shows. Both have premium builds with built-in voice assistant support and immersive Dolby Atmos sound. The Sonos has a better stereo soundstage, though the Samsung's sound is a bit more controlled and even out-of-the-box. The Samsung supports more wireless playback options, and it has two HDMI In ports for video passthrough, unlike the Sonos. Plus, it supports more audio formats and is more customizable, thanks to its EQ.

Bose Smart Soundbar 900 with Speakers + Bass Module

The Bose Smart Soundbar 900 with Speakers + Bass Module is better than the Sonos Arc with Sub + One SL Speakers. The Bose has a better soundstage performance, and it supports more wireless playback options such as Bluetooth. Its default sound profile is also more balanced than the Sonos. That said, you can use the Sonos' bass and treble adjustments to create a more neutral sound profile if you prefer. 

Sonos Arc

The full 5.1.2 setup of the Sonos Arc with Sub + One SL Speakers is much better than the Sonos Arc soundbar by itself. Adding the two rear satellites provides a much better surround sound experience, which is very immersive with surround content. It also makes the soundstage wider, although it does lose a bit of focus. The added subwoofer also creates more bass. On the other hand, the standalone soundbar might be a better option for people with limited space.

Sonos Beam (Gen 2) with Sub Mini + One SL Speakers

The Sonos Arc with Sub + One SL Speakers is better than the Sonos Beam (Gen 2) with Sub Mini + One SL Speakers. They're both very premium Dolby Atmos setups with built-in voice assistant support. However, the Arc is bigger, and it gets louder with less compression at max volume. Also, it provides a more immersive listening experience, especially with Dolby Atmos content. Subjectively, it reproduces more height in the soundstage, and objects seem to come from more accurate locations in the space around you.

Sony HT-A7000 with Speakers + Bass Module

The Sonos Arc with Sub + One SL Speakers is better than the Sony HT-A7000 with Speakers + Bass Module. Both setups have premium builds and versatile performances, but the Sonos has better soundstage, surround, and Atmos performances. It also gets louder with less compression at max volume. However, only the Sony has a Full HDMI In port for high-quality passthrough.

JBL Bar 1000

The Sonos Arc with Sub + One SL Speakers and the JBL Bar 1000 are both very premium soundbars with different strengths. The Sonos is a bit more expensive, but it's much better built and has built-in voice assistant support. Plus, it offers a wider and more immersive soundstage performance. Even though it comes with two fewer surround channels than the JBL, it still offers great performance with surround content. However, it doesn't support Bluetooth like the JBL and lacks Full HDMI In ports, too. Depending on your listening habits, you may find that the JBL is the better value overall.

Bose Smart Soundbar 900

The Sonos Arc with Sub + One SL Speakers is better than the standalone Bose Smart Soundbar 900. The Sonos full setup has a dedicated sub that helps it reproduce a more extended low-bass. It also comes with satellites and more sound enhancement features. Its surround performance is better, too. That said, the Bose has more wireless playback options. You can also upgrade it with a sub and satellites for better performance.

LG S95QR

The Sonos Arc with Sub + One SL Speakers is better than the LG S95QR. While they're both very premium setups, the Sonos offers a wider, more immersive soundstage, and its surround and Atmos performances are better overall. That said, it doesn't come with as many sound enhancement features as the LG. However, its default sound is quite neutral, so you don't really need them. 

Sony HT-A9 with Bass Module

The Sonos Arc with Sub + One SL Speakers and the Sony HT-A9 with Bass Module are both very premium setups. The Sonos is a 5.1.2 setup with better center and surround performances, and it can also get louder with less compression at max volume. There's even an optical port available, which the Sony lacks. That said, the 4.1.4 Sony has a very unique design and better soundstage and Atmos performances. There's even a Full HDMI In port for high-quality passthrough, unlike the Sonos.

Sonos Ultimate Immersive Set with Arc

The Sonos Ultimate Immersive Set with Arc is better than the Sonos Arc with Sub + One SL Speakers. Both setups take the Sonos Arc paired with a Sonos Sub but use different satellite speakers. The Ultimate Immersive Set uses the Sonos Era 300 speakers, with up-firing drivers built in for a more immersive sound, especially with surround sound and height content. You get a more clear and real feel with sound effects as a result.

Bose Smart Soundbar 700 with Speakers + Bass Module

Depending on your listening habits, you may prefer either the Sonos Arc with Sub + One SL Speakers or the Bose Smart Soundbar 700 with Speakers + Bass Module. The Sonos is better for movies, as it has a better surround performance and it supports Atmos content.

The Sonos Arc full setup has a great stereo frequency response. This soundbar has fairly balanced sound, especially in the mid-range, where most voices and lead instruments reproduce. Overall, it's suitable for listening to most music genres, and you don't have any trouble following the action on screen with your favorite TV shows. When we retested the bar with firmware version 14.18, we noticed an improvement in its low-frequency extension. As a result, there's a little more rumble in the mix, especially when bass-heavy genres like EDM and hip-hop, and a touch of extra brightness in the treble.

With calibration and its room correction feature turned on, the Sonos Arc full setup has a great stereo frequency response. Setting the treble to '-1' reduces the extra brightness in the mix, so you enjoy a really balanced sound with stereo content. There's still plenty of rumble in the bass, too.

This soundbar setup's stereo soundstage is great. It sounds wider than the standalone Sonos Arc by itself, although the focus isn’t as good. Nevertheless, it’s still fairly good and objects come from an accurate location rather than a diffused location. For a 5.1 setup with an even better soundstage performance, check out the Bose Smart Soundbar 700 with Speakers + Bass Module.

The Sonos Arc has great stereo dynamics. The bar gets loud, so it easily fills large, more open living spaces with sound. That said, after updating the bar to firmware version 14.18, a little more compression entered the mix when turned up to max volume, particularly in the bass range. It's fairly minor, all things considered, though.

The Sonos Arc with Sub + One SL Speakers has an impressive center channel performance. Thanks to its dedicated center channel, it can reproduce clear and accurate dialogue. While the frequency response lacks a bit of bass, this shouldn't be too noticeable in real-life as there isn't a lot of bass present with content played over the center speaker.

This 5.1.2 full setup has a satisfactory surround performance. With dedicated satellite speakers, sounds seem to be coming around you rather than from just in front. The sounds on surround tracks are only played by the satellites, and nothing comes from the bar itself, giving you a very good surround experience.

The Sonos Arc with Sub + One SL Speakers supports Dolby Atmos content. It uses up-firing speakers on the bar to bounce sound off the ceiling and back to you to simulate height. However, this doesn't sound as immersive as dedicated down-firing home theater speakers. Its satellite speakers don't have up-firing speakers, either.

The bar offers a wide and immersive-sounding soundstage with Atmos content. Sometimes, the soundstage seems a bit fake and exaggerated from pushing the sound to the sides of the room, but overall, the experience is quite enjoyable. Compared to the standalone Sonos Arc, the full setup has better focus, especially for sound objects that come from overhead. If you want an even better overhead sound, check out the Sonos Ultimate Immersive Set with Arc, which adds up-firing drivers onto the satellites for a more clear and real feel.

The Sonos Arc full setup has plenty of sound enhancement features. It has a 'Trueplay' room correction feature that adjusts the setup’s audio reproduction based on the room it’s set in, but it’s only available on iOS. Unfortunately, unlike the Samsung HW-Q990B and the LG S90QY, it doesn’t have a proper EQ for you to customize the sound, but you can still play around with the bass and treble adjustment settings. You can find every customization option in the compatible Sonos app, but you won’t be able to use the room correction feature on Android.

The Sonos Arc doesn’t have a lot of ports. It only features a single HDMI ARC port, so you won’t be able to use this soundbar as a hub for your different devices. It also features an Ethernet port to connect it to your home network, and it comes with an HDMI to Optical adapter. Unlike the Sony HT-A7000 with Speakers + Bass Module or the Samsung HW-Q990C, it doesn't have a Full HDMI In port, so you can't do video passthrough.

Audio latency falls within good limits if you're using an ARC connection. Your audio and visuals will be synced up. That said, some apps and TVs compensate for latency differently. While there's a TV Dialogue Sync feature available in the Sonos app to give you more control, there are only four settings to pick from, ranging between 75 ms to 2000 ms of delay possible.

This bar includes an HDMI to Optical adapter. Using this connection, you'll also experience low enough latency that your audio stays in sync with your visuals. Some apps and TVs can compensate for latency differently, so your real-world experience may vary. Some users have reported latency issues when connecting the Sonos Arc to LG TVs, but we didn't notice any issues with sound cutting in and out or audio delays. Let us know in the forums if you have a similar experience.

Like all Sonos soundbars, this one has fairly limited wireless capabilities. You can't cast via Bluetooth, and only Wi-Fi is supported. On the upside, there are a few apps like Spotify that have built-in support so that you can cast easily to the bar. For iOS users, the bar also supports Apple AirPlay 2. It also features both Google Assistant and Alexa built-in.
