Cinematic performance from a single soundbar

Immersive Dolby Atmos® sound

Uni-Q® MX driver technology
Specially developed Uni-Q® MX coaxial drivers position the tweeter at the acoustic centre of the midrange driver, creating accurate imaging and consistent sound throughout the room while maintaining exceptional vocal clarity.
Deep, controlled bass
Four P185 racetrack bass drivers featuring Velocity Control Technology (VECO) deliver deep, controlled bass with significantly reduced distortion and vibration, maintaining clean low-frequency performance even at high listening levels.
Music Integrity Engine® for Cinema
KEF's Music Integrity Engine® for Cinema continuously optimises every driver through advanced DSP processing, improving channel integration, dialogue intelligibility and surround sound precision.
Intelligent room optimisation
Intelligent Placement Technology (IPT) automatically adjusts the sound output according to the soundbar's position within the room, helping achieve balanced and accurate sound regardless of installation location.
Modern connectivity
The XIO features HDMI eARC, optical input and subwoofer output, while Wi-Fi 6, Bluetooth 5.3, Apple AirPlay 2, Google Cast, Spotify Connect, TIDAL Connect and QPlay provide seamless access to music streaming services and wireless playback.
