Product Information
”KEF's first soundbar isn't cheap, but for those that can afford it, the XIO is the best premium option right now.” ’What Hi-Fi?’ 2025 award-winner.
KEF’s first soundbar – it’s a winner straight out of the blocks
Scooping up awards at its first attempt, the KEF XIO may be late to the soundbar party, but it’s got the quality and performance to easily be amongst the very best. Within its sleek and stylish casing you’ll find KEF’s famous Uni-Q drivers, which are ideal for immersing you in rich, Dolby Atmos and DTS:X cinema sound. The XIO also makes a great music speaker, with a wide range of streaming options available via app control.
Your choice of 3D cinematic sound
When it comes to surround sound formats, KEF’s first soundbar has all the best options covered. For classic, immersive surround sound, the XIO is compatible with Dolby Atmos. For non-Dolby Atmos encoded movies and TV, there’s also DTS:X. Both systems recreate convincing 3D audio, with the sound of overhead aircraft and tropical rainfall brought to life by the KEF’s 5.1.2 speaker configuration.
Your music, made immersive
With Sony’s 360 Reality Audio, music is more immersive than ever. The technology ‘pushes’ the sound around the room, giving the feeling of being surrounded by sound – just like at a live concert. There’s also virtualisation technology that converts audio from mono/stereo sources into multi-channel, transforming every sound source into an enveloping listening experience.
KEF Uni-Q drivers for expansive sound
KEF’s Uni-Q speaker technology places the tweeter within the woofer’s central core, giving pin-point accuracy and harmonious sound across the mid and upper frequencies. With three Uni-Q drivers onboard, the XIO has the front left, centre and right channels covered. For the side-firing ‘surround’ drivers, KEF has fitted full-range units.
Add an optional wireless subwoofer
Featuring four built-in woofer units, the XIO creates a richly balanced and dynamic sound. You can take this to the next level by adding your choice of active subwoofer and connecting via the optional (at extra cost) KEF KW2 RX Receiver. This wirelessly receives its bass signal from the soundbar and connects directly to your subwoofer’s input. For the most seamless sonics, pair with the KEF KC62, KC92 or Kube subwoofers.
Stream in style
More than just a master with movies, the XIO has a whole host of music streaming options available too. Connect via Wi-Fi, AirPlay, Chromecast or Bluetooth and effortlessly stream your choice of music. For direct access to your favourite streaming services, Spotify, TIDAL, Apple Music, Amazon Music and Qobuz Connect are all embedded within the KEF Connect app.
The hub of your connectivity
For multi-source connectivity, the XIO has an HDMI eARC connection. Plug in your TV and this versatile connection carries the sound from all the audio sources connected to your TV. For other sources, such as a games console, or even a CD player, there’s an optical digital input.
Sleek style
Available in Slate Black or Silver Grey, this sleek and stylish soundbar looks good with any TV. The premium aluminium and splashproof fabric finish is durable too. When it comes to positioning, you can choose between wall or shelf mounting, without compromising on sound quality. Built-in sensors detect the soundbar’s position and automatically adjust the settings for optimal performance.

With its lean yet powerful bass and smooth stylish design, the KEF KC62 has what it takes to make a deep impression.
Small but mighty
At around 250mm in each direction, the KEF KC62 certainly qualifies as a compact sub. Using twin drivers in Uni-Core Force Cancellation configuration and powered by a 1000 watt amp, however, the bass performance is never anything less than mighty.
Uni-Core Force Cancellation delivers the power, without the bulk
Instead of using a large woofer, which inevitably leads to a larger cabinet, the KC62 is fitted with twin drivers, fitted back-to-back. KEF’s ingenious version of force cancelling uses a single magnet and concentric voice coils (Uni-Core), to deliver a mighty punch while reducing cabinet volume by over a third.
The power to impress
With 500 watts of Class-D amplifier power available to each woofer, the KC62 produces a mighty 1000 watts in total. This huge swell of power means that the bass isn’t just deep and loud enough but also kept under tight control, for maximum dynamic attack.
P-Flex surround for a smooth, even response
The KC62 is fitted with KEF’s P-Flex surround that’s designed to reduce cone movement resistance – especially at lower volume levels. This means you get a seamless response, without the ‘lumpy’ bass that can afflict lesser subs.
Smart Distortion Control
Using a powerful, bespoke DSP (Digital Signal Processor), the KC62 constantly analyses the signal for overloading, with SmartLimiter stepping in if needed to reduce distortion. Added to this, Smart Distortion Control technology uses current measurements to detect and correct any potential distortion. This reduces THD (Total Harmonic Distortion) by up to 75%, giving you a much purer bass response.
Adjusts to suit your room
As well as the usual volume, crossover and phase controls, the KC62 also features an EQ mode – giving you the best possible sound in your room. Choose between ‘Room’, ‘Wall’, ‘Corner’, ‘Cabinet’ and ‘Apartment’ settings for optimised sound in any setting.
A subwoofer you’ll be proud to show
Crafted from extruded aluminium, the KC62’s curved cabinet is in a different league to most other ‘boxy’ and bland subs. Finished in Carbon Black, Mineral White or new Titanium Grey, the KC62 deserves to be proudly on display, rather than tucked out of sight.
Enjoy the sound and sight of powerful bass, with the KEF KC62.
Connect a KEF XIO soundbar to any subwoofer, wirelessly, with the KEF KW2 RX receiver.
Make a wireless connection with a KEF subwoofer
The KEF KW2 receives wireless signals from the XIO soundbar, transmitting them to a connecting subwoofer. Ideal for use with KEF subwoofers, it’s designed to plug into the back of most KEF active subs, including the KC62, KC92 and Kube models.
Works with any active subwoofer
The KEF KW2 doesn’t have to be paired with a KEF subwoofer. Almost any active subwoofer can be connected via the KW2’s analogue/optical digital 3.5mm output.
Link your active sub wirelessly to your XIO soundbar, with the KEF KW2.
