Immersive home theater sound
Arc — Sonos's first Dolby Atmos-capable sound bar — sounds really great on its own, with precisely angled side-firing and up-firing speakers that create a multi-dimensional soundstage full of depth and detail. That's pretty hard to improve upon, but we did it by bundling it with the new third-generation Sonos Sub and a pair of One speakers for full-on surround sound. I was very impressed with this system when I got my hands on it recently. It was super-easy to set up, and it sounded fantastic.
This Sonos system is an easy and stylish way to get great home theater sound.
Adding the Sonos Sub brings more to the table than just booming bass. When the sub is added, it takes on the lowest frequencies — leaving Arc's amplifiers free to drive the high and midrange frequencies.
The included pair of One surround speakers are compact and unobtrusive, but they add an enveloping movie-theater feel to your living room.
Wireless convenience
The sub and surround speakers connect wirelessly with Arc, so you won't need to run connecting cables (though each one requires AC power).
Voice control options
Arc has both Amazon Alexa and Google Assistant built in, so when you want to play your favorite tunes, all you have to do is ask. And your assistant of choice can do more than just play music. You can ask for weather and traffic updates, create a shopping list, set reminders or alarms, and control connected smart home devices like lights and thermostats — all with your voice.
Don't miss a word
Many of us struggle to hear dialogue over the background noise in our favorite shows and movies. Arc can help with that. In addition to a dedicated center channel, it has a Speech Enhancement option that can help make dialogue more intelligible, so you don't have to turn on subtitles to keep up with the plot. This feature is accessed in the Sonos app.
Calibrated for your home
If you use the Sonos app on an iOS® device, you can use that iPhone® or iPad® to optimize your system's sound quality for the unique acoustics of your room. This feature — called Trueplay — uses the mic built into your iOS device to measure how the sound from Arc, Sub, and the One surround speakers reflects off your walls and furnishings, and it adjusts the system's settings accordingly. It even calibrates the height channels.
Expand your system
You can expand into other areas of your home by adding another or the larger , in every room where you want to listen to music. Or, you can even go portable with the more rugged, battery-powered . For even more bass in your home theater setup, you can add a second a .
Compatibility notes
This system is very easy to get up and running. Arc has a single HDMI eARC port for connecting it to your TV. If your TV has eARC, you are all set to pass an Atmos signal through to your bar from either a connected Blu-ray player or your device's streaming services.
If your TV doesn't have eARC, you can still get great audio quality, but there are limitations on the types of signals that can pass through to Arc. If your TV is fairly new, there is a good chance that a simple ARC connection will pass the Dolby Digital Plus format that is used by streaming services to deliver an Atmos signal. If you're unsure what formats your TV can pass, check the owner's manual.
Arc will also work with TVs that don't have HDMI thanks to the included HDMI to optical adapter. It will still sound a lot better than your TV, but you will not be able to pass an Atmos signal this way.
