Why Sonos Arc Soundbar?
The Sonos Arc Soundbar isn’t just a pretty speaker—it’s a high-end sound system that adjusts to the specific acoustics of your room. Thanks to 11 powerful drivers, upward-firing speakers, and its digitally precise tuning, it produces a 3D surround soundscape all around you.
Unlike a traditional soundbar, it’s a Sonos speaker that works with the Dolby Atmos 3D audio surround sound track found on many of your favorite movies and TV shows—think overhead height channels for sound effects (want to hear Thor’s hammer spinning above you without a ceiling fan whirling?). Whether it’s the swoosh of a helicopter or the gentle patter of rain, Atmos brings power to audio at home.
Sonos Arc Setup: Getting Started
The best thing about the Sonos ecosystem is how simple it is. The Sonos Arc installation process is straightforward and requires only a few steps:
● Placement—The Arc should be placed under the TV, or wall-mounted if desired, or on a stable TV stand that can support the weight of the product with at least 4 inches (10 cm) of clearance around it.
● Connection—Use your TV’s HDMI eARC or optical output to securely hook the A90 up. If your TV does not support eARC, you can use HDMI ARC to connect the television to the soundbar.
● Sonos App—Get the Sonos app (iOS/Android), and follow setupinstructions. The app will guide you through Wi-Fi setup, software updates, and initial sound checks.
● Voice Control—Pair with Amazon Alexa or Google Assistant to enable voice control.
With these easy steps, you’ll be able to start enjoying quality sound in no time.
Sonos Arc Room Calibration for Perfect Sound
No two rooms are ever alike, which is why calibration with Sonos Arc room tuning is essential.” Courtesy of Sonos By deploying the Trueplay technology of their own (which currently is available on iOS devices), the system is able to leverage how sound bounces off your walls, ceilings, and furniture.
This calibration ensures:
● Balanced sound regardless of where you sit.
● Accurate Sonos Arc bass playback without midrange fatigue.
● Realistic Atmos effects that you can hear all around your room.
Trueplay automatically adjusts the audio for the best sound wherever you place it—so if you ever move your Arc or change things up in your room, Trueplay will make sure that performance stays the same.

Bass Performance Sonos Arc: The Deep, The Rich
One question we get asked a lot is regarding how well the Sonos Arc performs in providing bass. Right out of the box, it produces some excellent low-frequency sound due to its included woofers. That’s enough punch for action films and music playback in most rooms.
But in larger rooms, or for users who desire thunderous bass, connecting the Arc to Sonos Sub adds a lot of punch to its performance. The Arc is masterful with mid and high frequencies, while the Sub provides depth and rumble you can feel.
Sonos Arc vs. Beam: What Should You Pick?
Maybe you’re thinking about a Sonos upgrade and ask, “Sonos Arc vs. Beam?” Here’s a quick comparison:
● Sonos Beam (Gen 2)—Small size and Dolby Atmos support, but fewer speakers and less bass. Ideal for smaller rooms.
● Sonos Arc—Bigger, louder, and fitted with dedicated upward-firing drivers for supreme Atmos immersion. Great for medium to large rooms.
Bottom line: If space and budget permit, the Arc is the better option for those who crave cinematic audio at home.
Sonos Arc Dolby Atmos Sound: Best Practices
Here are some best practices for getting the maximum sound out of your Sonos Arc Dolby Atmos:
● Use HDMI eARC – Ensure your TV supports eARC for full Atmos signal.
● Mount Smartly – Wall-mounting allows upward-firing speakers to project Atmos height channels correctly.
● Re-run Calibration – Always recalibrate if your room layout changes.
● Enhance with Add-ons – Add Sonos Sub or surrounds for true 5.1.2 or 7.1.2 setups.
Those simple changes can be the difference between halfway decent sound and a memorable listening experience.
