Cinematic Sound, No Compromise
At the core of XIO is support for Dolby Atmos, DTS:X, and 5.1.2-channel audio. Whether it’s a sweeping film score or subtle ambient details, sound moves around the room naturally and with impact. KEF’s Music Integrity Engine works in the background to keep every element aligned—bringing explosions, whispers, and score to life in vivid detail. From casual TV nights to full-on movie marathons, the experience always feels big, spacious, and remarkably lifelike.
Clear Dialogue, Rich Detail
XIO uses KEF’s Uni-Q MX driver array to disperse sound more evenly, so no matter where you sit, you get the same clarity and precision. Dialogue sits front and centre—ideal for catching every line without needing to raise the volume. You can enhance vocal clarity even further using Dialogue Mode via the app or remote. It’s especially helpful in busy family rooms or open-plan spaces where background noise can be a distraction.
Bass You Can Feel
With four long-throw P185 bass drivers and KEF’s Velocity Control (VECO) technology, XIO produces deep, tight low-end that’s as impactful as it is controlled. It easily fills the room without distortion or boom. If you want even more presence, you can add a KEF subwoofer wirelessly using the KW2 RX receiver. Whether it’s a cinematic score, a gaming session, or bass-heavy music, the low frequencies always land with precision and weight.
