Beam Ultra review: Atmos power in a compact Sonos bar

The Sonos Beam Ultra is a Dolby Atmos soundbar that upgrades the Beam Gen 2 with nine drivers (7.1.2) and a redesigned center coaxial transducer for clearer dialogue and wider sound, delivering room‑filling cinema sound and engaging music for a compact bar. It supports Dolby Atmos (but not DTS:X), has a single HDMI eARC port with no passthrough, USB‑C, Bluetooth 5.3, and Line‑In via adapters, plus Quick/Advanced Trueplay tuning and an AI dialogue boost. While it doesn’t project sound as directly as some rivals and Arc Ultra remains the more authoritative option, it offers standout performance for movies and music at £699/$699/AU$1099 and sits as a compelling mid‑range upgrade within Sonos’s lineup, ideal with a sub and/or surrounds for a fuller system.
