INTRODUCING THE SONOS ARC ULTRA PREMIUM STREAMING SOUNDBAR
/The Arc Ultra is the latest addition to Sonos' soundbar lineup, replacing the Arc at the top of their three-model range. Promising enhanced performance and new features, it’s set to be their most immersive soundbar yet. One has just arrived at Audio T Swindon, and we’re wasting no time unboxing it and putting it through its paces. Read on for our first impressions!

Connectivity
Placing the Arc Ultra next to the outgoing Arc, we can see it’s slightly wider and lower—good news for those looking to avoid obstructing their TV screen. The extra width allows for a significant increase in the number of drivers housed within the casing.
Connectivity remains similar, with just the eARC HDMI port, but Sonos has now added Bluetooth support. A vast range of streaming services are built in, and the Ultra is compatible with Amazon Alexa and Google Assistant.
To optimise performance in any environment, Trueplay tuning is available, and for the first time, it now works with Android devices as well as iOS.
Control is straightforward, whether using a TV remote, the Sonos app, or the touch-sensitive controls on the unit itself for Play, Pause, Skip, Back, Volume, and voice assistant activation.

Construction
Inside the slim, perforated metal casing are fourteen drivers arranged in a 9.1.4 configuration—an upgrade from the Arc’s 5.0.2 setup. To perform at its best, the Ultra shouldn’t be placed inside a cabinet, as the upward-firing drivers require open space.
A notable addition is a dedicated internal bass unit, a feature Sonos is particularly proud of. This innovative technology, called Sound Motion, uses a unique flat, brick-like driver design. Instead of placing the motors behind the membrane, they are positioned at the sides, allowing for greater movement and significantly more bass output than the original Arc—all while requiring less space.

Comparison with the Arc
Comparing the two side by side is fascinating. I expected the Arc Ultra to outperform the Arc, but the difference is far more pronounced than I anticipated.
My go-to movie test, Ratatouille, is packed with everything—deep bass, dynamic shifts, and great spatial effects. A standout moment is the scene where the ceiling collapses in the old lady’s cottage, an excellent test of bass depth and agility. The Arc Ultra not only reaches slightly lower frequencies than the Arc but, more importantly, is significantly more responsive. Later in the film, as the rats escape to the river, the Ultra delivers far superior soundstaging of the rain and thunderstorm, while the trip through the sewers digs deeper into the lower bass frequencies.
Sonos soundbars have always excelled with vocals—essential for following dialogue without constantly adjusting the volume. The Arc Ultra, however, takes this a step further, offering the clearest dialogue performance yet. The speech enhancement feature provides even greater vocal clarity when needed. Additional Sonos speakers and subwoofers can be paired with the Ultra for full multi-channel surround sound and even deeper bass.

Conclusion
The Arc Ultra represents a significant step up in performance over the outgoing Arc. Is it the best premium soundbar on the market? I can’t say for certain—but I wouldn’t bet against it.
Is it as good as a dedicated 5.1, 7.2 or 9.2 home cinema system? Unlikely. Even with additional Sonos speakers, it can’t quite match the impact of five or more well-placed speakers and a subwoofer, driven by a high-quality home cinema amplifier. However, if you’re looking for a premium upgrade to your TV’s speakers, crave the convenience of wireless technology or are already invested in the Sonos ecosystem, you may not need to look any further.
