Transcendent Cinematic Sound

All-in-One performance.

Delivering hyper-realistic, high-resolution sound, XIO creates a truly cinematic audio experience through a 5.1.2 configuration and 12 Class D amplifiers.

Five Main Channels: Three Uni-Q MX drivers and two full-range drivers support the left, centre, right, left surround, and right surround channels, creating an expansive soundstage that delivers remarkably realistic audio throughout the room.
Subwoofer Channel: Powered by four P185 LF drivers, it ensures impactful bass that enriches your sound. This high aspect ratio racetrack performs like a 4 x 4'' driver at a much-reduced height, delivering deep, detailed bass.
Two Overhead Channels: Supported by 2 Uni-Q MX drivers, these add height to your sound, amplifying sound effects for truly immersive experiences.

High-fidelity spatial audio.

With KEF’s Music Integrity Engine (MIE) for Cinema, XIO supports Dolby Atmos, DTS:X, and Sony 360 Reality Audio, and its advanced up-mixing technology intelligently expands the soundstage, converting mono and stereo sources into a rich, spatialised audio environment.

Dolby Atmos: This popular spatial audio format places sounds in specific locations in a three-dimensional space. This gives you the impression that sound moves around you — like a bullet in your favourite Netflix thriller whizzing right past your shoulder.
DTS:X: This format also uses object-based audio to create immersive surround sound that moves around you. With DTS:X technology rain sounds like it is falling from ceiling to floor rather than just being heard above. Experience it through IMAX Enhanced on Disney+.
Sony 360 Reality Audio: Surrounds you in captivating sound, bringing audio to life like never before. Experience music as the artist intended and feel as if you're at a live concert.
Up-mixing of Mono/Stereo: This virtualisation technology converts audio from mono/stereo sources into multi-channel, expanding the soundstage and creating an immersive audio experience.

Pristine dialogue and exceptional vocal clarity.

Midrange clarity is key to an exceptional home entertainment experience, and XIO ensures that every word is heard with remarkable detail. A dedicated Dialogue Mode within the EQ presets enhances vocal frequencies while reducing background noise, making speech effortlessly clear. Exceptional sound imaging delivers audio performance that rivals KEF’s renowned HiFi speaker systems, so that whether it’s a whispered conversation or a soaring musical score, every nuance is faithfully reproduced.

Pioneering Technology

Precision where it counts.

The XIO features six Uni-Q MX drivers, the miniature version of KEF’s iconic Uni-Q technology. These drivers ensure a balanced soundstage, delivering crisp, accurate audio across the entire room. The decoupler, engineered as a precise crossover, separates the LF cone and HF tweeter dome, a design that allows the diaphragm to move freely at low frequencies while isolating the dome for high-frequency precision. As a result, the XIO delivers full-bodied, high-fidelity sound for everyone to enjoy no matter where they are in the room.

Deep, detailed bass in a slim profile.

XIO’s P185 LF driver, enhanced with KEF’s P-Flex technology, ensures deep and detailed bass performance, offering a level of clarity and power rarely found in a soundbar. The high-aspect-ratio racetrack design (18cm/7" x 5cm/2") enables an ultra-slim profile while delivering performance equivalent to a 4” LF driver. The ample cabinet space allows for twin P185 drivers to be positioned back-to-back in a force-cancelling configuration that significantly reduces mechanical vibrations. This results in a pure and resonant low-frequency response, free from unwanted distortions. Adapted from KEF’s award-winning KC62 and KC92 subwoofers, P-Flex technology resists acoustic pressure within the cabinet, enabling the driver to move with greater precision and achieving deeper bass extension with remarkable clarity.

Revolutionary sound correction.

KEF’s patent-pending Velocity Control Technology (VECO) is the game-changing built-in sensor at the heart of the P185 LF driver. VECO monitors cone motion in real-time and employs a negative feedback loop to minimise distortion and compression. This ensures that the signal reaching the driver’s voice coil includes the intended musical signal alongside a correction for any deviations in the driver’s motion, maintaining system stability. As a result, distortion is significantly reduced, delivering pristine, undistorted clarity.

Smart and powerful.

The mastermind behind KEF's signature sound, Music Integrity Engine (MIE) for Cinema is our in-house written suite of DSP algorithms specially tuned for XIO that offers multi-channel processing, virtualisation and adaptive placement capability. Users benefit from immersive soundscapes that enhance movie watching and the ability to enjoy consistent audio quality regardless of the soundbar's placement.

Intelligent placement.

Intelligent Placement Technology (IPT) ensures consistent performance. It detects nearby objects to understand the surrounding acoustics. After gathering this data, the MIE algorithm automatically adjusts the EQ for enhanced audio output.

Connect and Stream

Stream anything.

The W2 Wireless Platform, adapted from the LS Wireless Collection, offers seamless access to a variety of music services, including Tidal, Amazon Music, Qobuz, and Deezer. You can also stream directly from native apps like Spotify Connect, Tidal Connect, and QPlay, ensuring full fidelity in your listening experience. For third-party apps, Apple Airplay and Google Cast allow seamless integration over Wi-Fi, or use Bluetooth 5.3 to listen to almost anything from your smart device.

Perfect fit with today’s TV.

Designed for flexibility, the XIO offers HDMI eARC, optical, and the option of RCA subwoofer output. While the soundbar itself has sufficient bass for majority of use cases, for those looking for that bit extra, any KEF subwoofer can be plugged in or paired wirelessly with the KW2 RX receiver, an accessory specifically designed to ensure effortless and reliable connectivity.

Effortless Control

Touch control panel.

XIO’s top panel makes for easy, one-touch control. Power your soundbar on or off, adjust volume or mute your sound. You can even select your audio source at the touch of a button.

Customisable remote.

Using InfraRed (IR) technology, the included remote was designed for long-distance and wide-angle control. It features a customisable favourite button for your most used function. Thanks to HDMI CEC, you can also use your original television remote to control the volume on the soundbar.

KEF Connect app.

Control the soundbar from the KEF Connect App on your phone for added convenience. Adjust your audio experience to your liking via the app's EQ settings.

Dialogue mode.

Select Dialogue Mode for enhanced speech clarity. This setting is ideal for content where dialogue is key, such as TV shows, documentaries and news programmes.

Night Mode.

Night mode is tailored for late-night viewing or situations where lower volume levels are preferred. It prevents sudden loud noises from disturbing others while maintaining an enjoyable audio experience at lower volume levels.

Design

Sleek, contemporary aesthetic.

XIO's minimalist and discreet design is crafted to look great with your home interior. Available in two finishes: Slate Black and Silver Grey.

Durable and stylish.

With a sleek aluminium top plate and splash-proof fabric, the XIO soundbar combines style and durability seamlessly. Its beautiful, minimal design is crafted to complement any living room, regardless of your interior design style.

Mounting options.

The versatile design allows for wall or shelf mounting without compromising on sound quality. A wall-mount kit is included in the box. Intelligent sensors detect the soundbar's placement and automatically adjusts for optimal audio.
