Why this model

The Sonos Arc Ultra is a premium 9.1.4 Dolby Atmos soundbar. It's for anyone who wants real cinema sound and great music in the living room without lining the walls with five speakers. A single HDMI eARC cable to your TV handles films, series and games. Over Wi-Fi 6, Bluetooth 5.3 or AirPlay 2, it also works as your main music speaker.

In this Sonos Arc Ultra review, we focus on what matters in a Belgian living room: its size, how it fits under the TV, what daily use looks like and what it doesn't do. All figures come from Sonos's official product page and the Amazon listing.

Sonos Arc Ultra design: a matte black bar made to be seen

According to Sonos, the Arc Ultra measures 75 mm high, 1,178 mm wide and 110.6 mm deep, and weighs 5.9 kg. It comes in a matte finish, in black or white. The grille wraps the entire front, with no display or loud branding. Touch controls sit on top, and a cable channel at the back keeps the setup tidy.

You can place it on a TV stand or mount it on the wall below the screen, and Sonos's own photos show both setups. At 7.5 cm tall, it slips under most TVs that stand on feet. Still, plan for a stand at least 1.2 m wide so it doesn't overhang.

Day to day: TV, music and voice

For TV, you connect it over HDMI eARC and keep using your usual remote, since Sonos lists TV remote compatibility. Speech Enhancement brings dialogue forward. Night Sound evens out volume peaks late in the evening, when the kids are asleep.

For music, you control it in the Sonos app over Wi-Fi 6, through AirPlay 2 from an iPhone, or over Bluetooth 5.3 from any phone. The far-field microphones support Sonos Voice Control and Amazon Alexa, depending on country and language, and a physical switch turns them off. Trueplay measures your room's acoustics and tunes the EQ, on both iOS and Android.

Sonos Arc Ultra key specs

According to Sonos, the Arc Ultra packs 14 speakers driven by 15 class-D digital amplifiers. There are nine silk-dome tweeters, two of them firing upward for Dolby Atmos height channels, plus six midwoofers and one Sound Motion woofer. That woofer pairs four magnets with dual diaphragms for deeper bass from a compact enclosure. Together they deliver 9.1.4 spatial audio.

Connectivity covers one HDMI eARC port, Wi-Fi 6 (2.4 and 5 GHz), Bluetooth 5.3 and AirPlay 2. The system can grow too: Sonos offers sets with a Sub 4 and a pair of rear Era 300 speakers for a full home cinema. You can also pair a Sonos Ace headphone to watch TV without disturbing anyone.

Who the Sonos Arc Ultra is for, and who should skip it

It suits you if you want a clean living room: one object under the TV for films, sport and music, with no cables running across the floor. It's also a good starting point if you already own Sonos speakers, or plan to add a sub and rear speakers over time.

Look elsewhere if you need a desk speaker or something portable: at 1.18 m and 5.9 kg, it stays in the living room. It's also not the right pick if you want to plug several HDMI devices straight into the bar, since it has just one HDMI eARC port, or if your TV stand is narrow.

Frequently asked questions

Is the Sonos Arc Ultra worth it for a living room?

Yes, if you want 9.1.4 Dolby Atmos from a single device under your TV. According to Sonos, it packs 14 speakers, including two upward-firing ones, and tunes itself to your room with Trueplay. It also works as your main music speaker over Wi-Fi, AirPlay 2 or Bluetooth.

What are the Sonos Arc Ultra dimensions?

According to Sonos, the Sonos Arc Ultra measures 75 mm high, 1,178 mm wide and 110.6 mm deep, and weighs 5.9 kg. So you need a TV stand at least 1.2 m wide, or a wall mount below the screen.

Does the Sonos Arc Ultra support Bluetooth?

Yes, the Sonos Arc Ultra supports Bluetooth 5.3 alongside Wi-Fi 6 and AirPlay 2. Bluetooth is handy when a guest wants to play their own music. For everyday listening, the Sonos app over Wi-Fi remains the main way to play.

How do you connect the Sonos Arc Ultra to a TV?

The Sonos Arc Ultra connects to your TV's HDMI eARC port with a single cable. After that, it responds to your usual TV remote. Since it has only one HDMI port, consoles and set-top boxes plug straight into the TV.

Can you add a sub and rear speakers to the Sonos Arc Ultra?

Yes. Sonos lets you pair the Sonos Arc Ultra with a Sonos Sub 4 and a pair of rear Era 300 speakers for a full Dolby Atmos home cinema. You can start with the bar alone and add the rest later.
