Sonos Arc Soundbar by Sonos Inc - Dolby Atmos home cinema with HDMI eARC

Sonos Arc Soundbar sits like a low, white surfboard under the TV, its perforated grille cool to the touch as you run your hand across it before a movie night. Once Tom Cruise’s helicopter blades start up in a Dolby Atmos scene, the Arc throws sound up and around the room rather than straight at your face.

Dolby Atmos and driver array

Sonos Arc is a premium soundbar designed for TV and home cinema, supporting Dolby Atmos through HDMI eARC or ARC on compatible televisions. Eleven high-performance drivers, including upward-firing speakers, handle left, right, center and height channels to create a three-dimensional sound field in the living room.

Product manager Ryan Taylor explains in a Sonos blog that the Arc’s acoustic architecture was tuned in collaboration with film sound engineers to keep dialogue sharp while preserving impact in effects-heavy scenes. Each driver sits behind that seamless metal grille, which gives the Arc its monolithic look but still lets sound breathe.

HDMI eARC and streaming integration

On the back of the Sonos Arc, the single HDMI port is the key connection: the soundbar relies on HDMI eARC or ARC to receive Dolby Atmos and other multichannel audio from the TV. Where televisions only offer optical output, Sonos includes an HDMI-to-optical adapter, though Atmos is then off the table.

Once connected, the Arc plugs seamlessly into the wider Sonos ecosystem via Wi-Fi, supporting Spotify Connect, Apple AirPlay 2, and direct streaming from the Sonos app. Voice control through Amazon Alexa and the Google Assistant is integrated, with microphones that can be disabled via a dedicated touch button for privacy.

Trueplay tuning and living room reality

In practice, the Sonos Arc is rarely used in a perfectly rectangular test lab. Living rooms have asymmetrical sofas, glass coffee tables and bookshelves. Sonos tackles this with its Trueplay tuning feature on iOS, which uses the phone’s microphone to measure the room and adjust EQ and timing accordingly.

Reviewers at What Hi-Fi describe how walking around the room with an iPhone while the Arc emits whooshing test tones feels slightly theatrical but leads to tighter bass and more consistent Atmos effects. Without Trueplay, the Arc still sounds competent; with it, the effect of a helicopter panning overhead becomes more precise and less smeared.

Design, dimensions and mounting

The soundbar measures roughly 114 cm in width, 11.6 cm in depth and 8.7 cm in height, matching the proportions quoted on the official product page. At around 6.25 kg, lifting the Arc onto a cabinet is manageable for one person, though the size makes a second pair of hands welcome when wall-mounting.

Industrial designer Tad Toulis, who has worked with Sonos, has spoken in interviews about the company’s insistence on minimalistic design that blends into the living space rather than shouting for attention. That philosophy is evident in the Arc’s clean cylinder form, available in black or white, with touch controls on the top instead of physical buttons.

Optional Sub and surrounds

While the Sonos Arc can operate as a standalone soundbar, Sonos aggressively markets it as the centerpiece of a modular system. Pairing the Arc with a Sonos Sub and a pair of Sonos Era 100 or Sonos One speakers adds dedicated low-frequency and rear-channel output, turning the setup into a 5.1.2-like configuration.

On Sonos’ German shop page for the Sub, which is also available in black and white finishes, the company underlines how the wireless connection keeps the living room free from trailing cables while delivering powerful bass. In practice, this upsell pipeline from Arc to full home theater bundle matters financially because accessories and add-ons lift the average selling price.

Software updates and longevity

Sonos CEO Patrick Spence regularly emphasizes in quarterly calls that the company’s hardware is designed to stay in the market for many years, supported by ongoing software updates. The Arc has already received firmware improvements that tweak surround processing and add features such as support for new streaming services, all delivered over Wi-Fi.

For buyers, this means the soundbar is less tied to a specific TV generation. As streaming services roll out new audio formats or features, Sonos can respond with software changes rather than forcing an immediate hardware upgrade, a point that reassures users nervous about rapid obsolescence.

Pricing, markets and availability

On the Sonos official site, the Arc is currently listed at around 999 euros in Germany, positioning it clearly in the premium soundbar segment. In the US market, the price typically sits at around 899 dollars, according to major retailers such as Best Buy. Discounts do appear occasionally, but Sonos tends not to chase bargain pricing.

Availability extends across North America, Europe and parts of Asia-Pacific, with Sonos selling the Arc directly and through retail partners. Buyers in smaller markets sometimes rely on online retailers rather than local audio shops, but the product is a standard part of the Sonos portfolio, rather than a limited regional variant.

Sonos Arc and Sonos Inc stock

For Sonos Inc, the Arc is part of the home theater segment alongside Beam and Sub, which management has highlighted as a growth driver in earnings calls as more households upgrade to Atmos-capable TVs. The Sonos Inc stock (ISIN US83570H1086) reflects these dynamics alongside broader demand for connected audio hardware.
