Sonos’ Beam soundbar has been a mainstay of the brand’s evolving home theater collection since it debuted in 2018. Part soundbar, part smart speaker, and all Sonos, the Beam’s minimalist aesthetic and impressive smarts have made it a favorite for those looking to upgrade their TV sound the Sonos way. But there’s a new rival in Sonos land: the Sonos Arc.

With the Arc, Sonos is rewriting its own home theater playbook, tossing out the pricey Playbar for something even bolder. Where the Beam is sleek and compact, the Arc is big and brash, offering booming audio from nearly a dozen individual drivers, including upward-firing speakers for Dolby Atmos content. So which is right for you? We put the two head-to-head so you can decide if you should double down on the Arc, or stay sensible with the Beam.

Well, here’s an easy one to get us going. If you’re going by price alone, it’s the Beam all the way. At $399, the Beam is still an investment for most budgets, but it pales in comparison to the $799 you’ll shell out for the Arc—especially if you’ve just purchased a new TV. But, of course, there’s much more to the story here. Those looking for the best investment for their soundbar purchase will want to read on to see where the rubber hits the road.

When it comes to size, the Beam is an easy fit. Literally. At 25.6-inches across, 2.7-inches high, and 3.9-inches deep, the bar slides smoothly into virtually any setup, without crowding the TV screen or sticking out from the sides of your console. The Beam’s rounded corners also give it some flair, standing out from the rectangular design of most bars, while its matte color scheme in either black or white is at once understated and stylish.

That said, the Beam’s relatively compact size means its soundstage is more limited than many similarly priced bars. Sonos officially recommends the bar for those with smaller TVs of 49-inches or less.

The Arc, on the other hand, is as brutish as Sonos gets. Corraling 11 individually powered drivers within its tubular frame, it’s a massive bar that makes a statement from the moment its placed on your TV stand. The Arc stands 45-inches across, and 3.4-inches high, meaning it may cover up the bottom of your TV display unless you choose to mount it (for an extra $79).

The Arc is still all Sonos, though, offering the same monochromatic color scheme as its sibling, along with the usual minimalist design aesthetic and premium trappings you’d expect from a Sonos product. Unwrapping either soundbar has a decidedly Apple feel, helping to ease your concerns over the premium pricing.

Both the Beam and Arc offer nearly identical connection options, including both Ethernet and WiFi connectivity along with HDMI ARC connection and an adapter for connecting to your TV’s digital optical input. The HDMI ARC connection allows you to connect to your TV’s HDMI ARC port and control the bar with a TV remote in most setups.

The Arc is almost exactly the same, with one small (but notable) exception: Sonos' latest bar includes the new HDMI eARC connection instead of the older HDMI ARC port. For most setups, this won’t matter much, but if you have a new, premium TV with HDMI eARC (2019 or newer) it is notable for two primary reasons: the ability to easily adjust A/V sync issues between the bar and your TV, and the ability to send uncompressed audio from your TV directly to the bar.

This latter means your TV can theoretically pass virtually any audio signal it receives to the soundbar undiluted, allowing the bar to decode the audio so your TV doesn’t have to. That means that you could connect a Blu-ray player directly to the TV and send the full, high-resolution audio directly to the soundbar. This is also important when it comes to Dolby Atmos content (more on that below). However, since the Beam doesn’t support Dolby Atmos, and isn’t really designed with high-resolution audio at the forefront, it shouldn’t matter much.

What’s more notable is that neither soundbar includes a spare HDMI input for plugging in a video streamer, gaming console, or Blu-ray player directly. In addition, neither bar offers an analog connection for legacy devices and, in true Sonos fashion, there’s no Bluetooth audio support either.

With the latest version of the Sonos app, the S2 controller, each bar is easy to control and set up for a wide variety of tasks. Those include the ability to connect and group with other Sonos speakers as a multi-room sound solution, as a group, or as a surround sound setup with a Sonos subwoofer and surround speakers like the Sonos One SL or the (much cheaper) Sonos/Ikea Symfonisk.

Both soundbars are also “smart” in that they allow you to use a voice assistant (either Google Assistant or Amazon Alexa) to control basic playback functionality and smart home functions via built-in microphones. That makes both the Arc and the Beam essentially high-powered smart speakers that also connect digitally to your TV.

While there’s no Bluetooth, Spotify Connect and AirPlay 2 make it easy to stream music from a wide variety of source devices from Spotify and Apple Music respectively, and multiple other music streaming services are built into the Sonos platform as well. You can also source CD-quality audio through the app, allowing you to playback audio files from a NAS drive in high-quality.

Of course, the big feature that separates these two bars is Dolby Atmos: the Arc has it, the Beam doesn’t. This inclusion, along with the Arc’s side- and upward-firing speakers allow it to do some very cool things when fed Dolby Atmos content.

Speaking of Dolby Atmos content, the Arc’s lack of a spare HDMI input makes it much harder to source the highest quality audio such as uncompressed Dolby Atmos via Dolby TrueHD from physical media like Blu-ray players. The only way to do this with the Arc is via a TV with eARC. Otherwise, the Arc is limited to compressed Dolby Atmos from your TV over Dolby Digital Plus. That said, the Arc is still a very impressive Atmos specimen.

Simply put, this one is no contest. The Arc may be somewhat limited in which form of Dolby Atmos content it can receive, set up best for compressed Dolby Atmos signals, but so is the source of most of the Dolby Atmos content you’re likely to see in the wild these days: streaming video. And feeding this soundbar Dolby Atmos movies from services like Disney+ is nothing short of a brilliant, cinematic thrill ride.

While neither soundbar comes with a subwoofer, the Arc has plenty of bass punch built right in (that’s what you pay for in both dollars and TV console real estate). And beyond the blooming, immersive soundstage of Dolby Atmos films and TV shows, the Arc just sounds luscious and smooth, regardless of what you’re sourcing. The bar has more than enough power for a standard TV room, filling the space with big, potent sound.

For its part, the Beam certainly holds its own when it comes to a bar of its stature. While it definitely can’t kick out the beefy bass of the Arc (let alone the Dolby Atmos immersion), it does offer clear and punchy sound for its size. That includes some impressive detail in the midrange and excellent dialogue clarity, though at times it can get a little snappy. The Beam is also a solid soundbar for music playback, offering more bass than you’d expect and the kind of effortless musicality in the upper register we’ve come to expect from all Sonos speakers.

For our money, there’s no question that the Sonos Arc is the more satisfying purchase, offering the features you expect from Sonos alongside room-filling sound, thrilling Dolby Atmos playback, and a sound signature that says premium through and through.

For its part, the Beam offers a wide chunk of the Arc’s features, including all the goodies of Sonos’ well-designed software and your choice of smart assistant flavors (with either Google or Alexa on tap), all in a sleek and unassuming profile. And it’s hard to argue with half the cost.

Still, if we’re looking for a Sonos soundbar right now, it’s the Arc that makes the best case, even at its towering size (and cost). With an eye on the future and an upgradeable Dolby Atmos configuration, this is a serious investment that should pay off for those serious about sound.
