Soundbars and audiophile brands don't always mix — but KEF's first attempt is a serious one. The XIO brings the company's driver technology and voicing to a single-bar 5.1.2 Atmos system that's as happy with music as it is with movies.
The ProductKEF XIO
The XIO packs six Uni-Q MX arrays (a dual-diaphragm design with its own mechanical crossover), four racetrack bass drivers, and two side-firing full-range drivers — 820 watts total across 12 Class-D amplifiers. KEF's VECO sensor system keeps the bass clean, while Intelligent Placement Technology detects the bar's orientation and auto-calibrates with a built-in mic. Connectivity covers HDMI 2.1 eARC, optical, Wi-Fi, and Bluetooth 5.3, with Dolby Atmos, DTS:X and Sony 360 support and a 34Hz–20kHz reach.
How it sounds
Bigger and more three-dimensional than a single bar has any right to be — dialogue stays crisp, Atmos height cues actually land, and it holds together as a genuine music system when the movie's over.
