KEF XIO Soundbar
Bring cinematic sound into your home with the KEF XIO, a premium Dolby Atmos soundbar designed to deliver powerful, immersive audio from a sleek all-in-one system. Built for films, television, gaming and high-resolution music streaming, XIO combines KEF’s advanced acoustic engineering with elegant modern design.
With support for up to 5.1.2-channel spatial audio, including Dolby Atmos, DTS:X and Sony 360 Reality Audio, the KEF XIO creates a wide, enveloping soundstage that places dialogue, effects and music with impressive precision. Whether you are watching a blockbuster, streaming a concert or enjoying your favourite series, XIO delivers a more engaging and realistic listening experience.
At the heart of the soundbar is KEF’s Music Integrity Engine®, working alongside Uni-Q MX drivers and four P185 low-frequency drivers with VECO technology. The result is clear vocals, detailed mids, spacious highs and deep, controlled bass from a compact, beautifully finished soundbar.
The KEF XIO is also designed for effortless connectivity. HDMI eARC makes it simple to connect to your television, while Wi-Fi, Ethernet, AirPlay, Google Cast, Bluetooth 5.3 and KEF Connect provide flexible ways to stream music throughout your home. For even greater impact, XIO can be paired with a compatible KEF subwoofer using the KW2 RX Receiver.
Available in Silver Grey and Slate Black, the KEF XIO Soundbar is an ideal choice for anyone wanting high-end home cinema performance without the complexity of a traditional surround sound system.
