The Sonos Arc is an distinctive soundbar, and never simply because it helps the immersive audio format Dolby Atmos. But the Arc has a few important shortcomings, solely one in all which could ultimately be remedied. The solely technique to utterly get across the different limitation is to attach the Arc to a late-model TV that helps HDMI with eARC (the improved Audio Return Channel that has thrice the bandwidth of the older HDMI ARC. You can read all about eARC in this story.)
Let me be up entrance: I actually, actually just like the Sonos Arc—therefore my bottom-line rating. It’s lovely to take a look at, Sonos is the undisputed grasp of mainstream multi-room audio, and it sounds completely implausible with each motion pictures and music. Also, Dolby Atmos assist isn’t the one motive it’s such a terrific speaker. But since both or each of the restrictions I’ve alluded to may be showstoppers for some, let me delve into just a bit element on that early on.
The Sonos Arc’s single-biggest shortcoming: It’s outfitted with only one HDMI port (it’s on the left facet on this photograph, reverse the ability connection).
Sonos Arc limitations
The first challenge is that Sonos elected to not assist multi-channel LPCM audio—not less than not at launch. A Sonos spokesperson informed me the corporate plans to launch a firmware replace so as to add that function, however couldn’t give me a date. If you’re not a gamer, you won’t care about this. But in case you are and the Nintendo Switch is your gaming console of alternative, this can bum you out as a result of LPCM is the one sort of multi-channel audio the Switch helps (you will get audio from a Switch linked to the Arc, it simply gained’t be encompass sound). Microsoft’s Xbox and Sony’s PlayStation each assist Dolby Atmos, though not each sport developed for these platforms does (actually, many use multi-channel LPCM audio). Even then, the Arc’s second limitation might render the Xbox’s and PlayStation’s Atmos capabilities moot.
This evaluate is a part of TechHive’s protection of the best soundbars, the place you’ll discover evaluations of competing merchandise, plus a purchaser’s information to the options you need to think about when buying.
That second challenge is extra problematic as a result of it’s bodily: The Arc has only one HDMI port. While that port helps each the unique ARC and the higher-bandwidth eARC, it relies upon fairly closely on the capabilities of the TV you’re connecting it to. If you personal a really latest mannequin TV that additionally helps eARC, you’re golden. You’ll join your Atmos-supporting supply machine—a Blu-ray participant, a sport console, an Apple TV 4K, or an Amazon Fire TV Stick 4K, for instance—to your TV’s HDMI ports, and also you’ll plug the Arc into the TV’s eARC port.
If you’ve got a recent-model sensible TV, its built-in apps would possibly even provide direct assist for Dolby Atmos, so that you gained’t want a separate field. Either method, your TV will ship audio data, together with Dolby Atmos, to the Arc over an HDMI cable and all will probably be proper with the world.
TVs with eARC, nonetheless, didn’t begin trickling into the market till 2018. To get round this limitation, Sonos might have adopted the instance of another soundbar producers and constructed two or extra HDMI ports into the Arc: You would have used HDMI ARC to ship audio from the TV’s tuner, apps, and different sources to the Arc, and the Arc’s second HDMI port would obtain audio from a Blu-ray participant or set-top field. That’s how Samsung engineered our present high choose within the high-end soundbar class, the 7.1.4-channel HW-Q90R.
Woofers on every finish of the Sonos Arc can bounce hold forth the partitions on both facet of the speaker to simulate entrance encompass audio system.
And if you need the finest audio expertise that Dolby can ship at present—lossless audio within the type of Dolby TrueHD, and immersive audio within the type of Dolby Atmos—you’ll wish to watch motion pictures on discs performed on a 4K UHD Blu-ray participant. Yeah, that’s old-school, but it surely means you don’t must have very high-speed web, which isn’t out there in all places. Streaming providers like Netflix embed Dolby Atmos information within the lossy Dolby Digital Plus to cut back the bandwidth necessities, however most solely provide it with their 4K service tiers, that are nonetheless out of attain of these with modest web connections. Netflix, for instance, recommends having a constant minimal obtain velocity of 25 megabits per second to get it.
So, when you don’t have quick web, you’ll be able to’t get Dolby Atmos on the Arc from streaming providers, and in case your TV doesn’t have eARC, you’ll be able to’t get Dolby Atmos on the Arc out of your Blu-ray participant. I couldn’t consider Dolby Atmos on the Arc as a result of I don’t have both: The quickest web I can get the place I dwell is about 16Mbps, and the mid-range 2017 Samsung QLED TV I take advantage of (particularly, mannequin quantity QN55Q7FAMF) doesn’t assist eARC. When I linked the Arc to the Samsung, the most effective audio I might get was Dolby Digital 5.1, even with a high-end Cambridge Audio CXUHD 4K UHD Blu-ray participant. If the Arc had two HDMI ports, or if the TV supported eARC, I might have listened to Dolby Atmos with Dolby TrueHD with the Blu-ray participant.
Whether bean counters dictated that the Arc ought to have only one HDMI port, or it was a benign want for simplicity on the a part of the product workforce, the end result will probably be equally unlucky for lots of people who’d prefer to expertise Dolby Atmos, however don’t have a TV that helps eARC. It’s a curious limitation both method, as a result of Sonos contains an HDMI-to-Toslink optical adapter within the field to accommodate even older TVs that don’t have HDMI in any respect. You can’t get Dolby Atmos that method both, after all, as a result of Toslink doesn’t have enough bandwidth to deal with Dolby Digital Plus or Dolby TrueHD.

Inside the Arc
Designed to be used with bigger TVs, the 45-inch large Arc is an imposing but elegant-looking soundbar, with a face that curves over a 270-degree angle (it’s out there in black or white). Eight elliptical woofers and three silk-dome tweeters reside behind its grill, every pushed by a discrete Class D amplifier. Two of the woofers are mounted on high to bounce top cues off your house theater’s ceiling, and two are mounted on finish caps to replicate hold forth your partitions.
There’s a built-in far-field microphone array for summoning both Amazon Alexa or Google Assistant (your alternative, however just one might be lively at a time). An built-in IR receiver means that you can use your TV’s distant to manage the quantity. Capacitive contact controls on the middle high of the speaker are offered for play/pause, quantity up/down, and to mute the microphone array. Swiping throughout this floor strikes you up and down your present playlist. A single LED reviews the speaker’s standing, and robotically adjusts its brightness primarily based on the ambient gentle within the room.

As with each different Sonos speaker, the Arc doesn’t include a distant management of its personal. You’ll use the wonderful Sonos app to configure and management the system, together with deciding on servers in your native community, Sonos’ own internet radio service, and the handfuls of third-party music providers Sonos helps. These vary from MP3-quality Spotify to the high-resolution audio providers Qobuz and Tidal—though Sonos nonetheless gained’t reveal if the S2 OS will assist higher-resolution audio (past the present restrict of 24-bit/48kHz, that’s).
The speaker’s 3.4-inch top was low sufficient that it didn’t encroach on the underside of my TV’s display screen, however I couldn’t audition it in that location. My TV is in a wall-to-wall built-in leisure heart that has folding doorways so I can disguise the TV when it’s not in use. So, I rested the soundbar in entrance of the leisure heart, atop a pair of tower audio system I’m within the midst of reviewing. This gave the drivers in the long run caps loads of area to do their factor. If you wish to dangle the practically 14-pound Arc beneath your wall-mounted TV, you’ll want the $79 Sonos Wall Mount. The speaker’s 4.5-inch depth ensures it gained’t stick too far out into your room.

Listening exams
Before I sat all the way down to carry out my listening exams, I tuned the Arc to my 13 x 19 x 9-foot (WxLxH) house theater utilizing Sonos’ Trueplay software program on an iPad mini. Trueplay could be very efficient, however tuning might be carried out solely utilizing an iOS machine, as a result of Sonos can predict which kind of microphone is onboard and the place it is going to be situated on the machine. The fragmented Android machine market doesn’t present the extent of predictability.
I began with motion pictures and TV exhibits, as a result of that’s what most individuals use a soundbar for. Watching the Blu-ray UHD model of Spiderman 3, the Arc impressed with its capability to swirl sound if not round the room not less than on a really large sound stage on the entrance of the room because the experimental particle accelerator transforms Flint Marko (Thomas Haden Church) into the villain Sandman. I used to be additionally very impressed with the bass response as the large machine powered up, contemplating there was no subwoofer within the image.
I had an identical expertise, at Sonos’ suggestion, watching the episode of the Netflix sequence Stranger Things the place the Russian scientists fireplace up a machine designed to open an interdimensional gate to the Upside Down. This was after all meant to point out off the Arc’s efficiency with Dolby Atmos, but it surely was enjoyable to look at even with simply Dolby Digital 5.1.
The all-new Sonos Arc helps Dolby Atmos and options eight woofers and three tweeters, together with two up-firing drivers and two encompass channels.
Indeed, the Arc is among the few soundbars I’ve listened to the place I didn’t really feel an acute want for a subwoofer. And that’s factor, as a result of Sonos makes the one subwoofers you’ll be able to pair with the Arc (any of the three generations of Sub will work). As fabulous as they sound (I bought a Sub Gen 2 a number of years in the past), the present Gen 3 mannequin prices virtually as a lot because the Arc: $699. Sonos crossed one merchandise off my want checklist when it introduced the indoor/outdoor Sonos Move to market in 2019. Now I’d prefer to see the producer introduce a smaller, less-expensive wi-fi subwoofer.
If you wish to go all the way in which with true encompass sound, you’ll be able to add any pair of powered S2-compatible Sonos audio system to the combination (as proven within the photograph up high). The checklist contains the Sonos One; the Sonos One SL (the identical speaker, much less the microphone array wanted for Alexa and Google Assistant); the Sonos Five; or the Sonos Play:1, Play:3, or Play:5 (Gen 2).
After watching just a few extra motion pictures, I switched my consideration to music, streaming tunes from the gathering of CDs that I’ve ripped and encoded in 16-bit, 44.1kHz FLAC. Playing “Down to the Nightclub,” from the Tower of Power launch What is Hip? revealed the Arc’s capability to ship scorching highs because the drummer struck his open hi-hat and instantly shut it once more. And the punch of the band’s legendary horn part left the room crackling with pleasure.
Moving to an much more meticulously combined album, Steely Dan’s Two Against Nature, I reveled within the Arc’s visceral bass response because it delivered “What a Shame About Me.” I had the identical expertise listening to the string bass opening the Blind Boys of Alabama’s cowl of Tom Waits’ “Jesus Gonna Be Here,” from the group’s album Spirit of the Century.
Is the Sonos Arc worthy?
The Sonos Arc is a good soundbar—with caveats. It sounds implausible, with crisp highs, thick midrange, and slabs of well-defined bass. It’s enticing to take a look at, and it’s a part of the most effective mainstream multi-room audio system on the planet. If you’ve got an iOS machine—or can borrow one for a couple of minutes—Trueplay can pull off some wonderful tips to customise the speaker’s sound to your room.
On the opposite hand, Sonos depends too closely on the capabilities of your TV in the case of delivering its greatest promise: Dolby Atmos assist. If you’re shopping for this speaker for that motive, suppose lengthy and onerous in case your TV doesn’t assist eARC. Even when you stream all of your motion pictures over the web, it’s very onerous to know if a TV that doesn’t assist eARC will probably be able to sending Dolby Digital Plus with Atmos metadata to the Arc. And it could’t be finished in any respect with a Blu-ray participant sending Dolby TrueHD and Dolby Atmos metadata, as a result of Sonos provides you simply that one HDMI port to work with.
