KEF XIO

The KEF XIO is presented as an all-in-one soundbar that combines power, elegance, and technological innovation in a single compact body. Its solid structure, crafted with meticulous attention to detail, reveals a refined design that blends seamlessly into any home environment without being intrusive. The premium fabric grille and the aluminum top panel contribute not only to the aesthetic appeal but also to the acoustic performance, reducing unwanted vibrations and ensuring a stable and consistent sound. Despite its compact size, it houses an advanced audio system with six 50 mm Uni-Q MX drivers and four P185 woofers, engineered to deliver deep, controlled bass down to 34 Hz and a frequency extension reaching 20 kHz with remarkable precision.

At its core lies an amplification architecture capable of delivering an instantaneous power of 820 W, distributed across eight Class D channels for mid-high frequencies and four dedicated to bass, ensuring a sound pressure level of up to 102 dB without distortion. Every acoustic detail is enhanced by KEF’s proprietary VECO technology, which precisely manages airflow, and the Music Integrity Engine, designed to provide spaciousness, vocal clarity, and natural dynamics. Compatibility with Dolby Atmos, DTS:X, and 360 Reality Audio transforms listening into an immersive experience, with a three-dimensional soundstage that surrounds the listener from all directions, including overhead effects. Adding to this is Intelligent Placement Technology, a system that scans the surrounding environment in real time and automatically adjusts equalization to optimize performance, eliminating the need for manual tuning.

On the connectivity side, the KEF XIO offers comprehensive solutions for any setup. HDMI 2.1 eARC and TOSLINK optical inputs integrate seamlessly with home cinema systems, while USB-C and RJ45 ports ensure reliable updates and wired connections. Wi-Fi 6 supports high-resolution streaming up to 384 kHz/24 bit, while Bluetooth 5.3 with aptX HD codec provides superior-quality wireless playback. Compatibility with Apple AirPlay, Google Cast, Chromecast, and UPnP makes it an integral part of the smart home ecosystem, with direct access to leading music services such as Spotify, TIDAL, Amazon Music, Qobuz, Deezer, and HIGHRESAUDIO, as well as internet radio and podcasts.

Its versatility is further expressed in the ability to integrate with an external subwoofer, connectable either via cable or wirelessly through the KEF KW2 receiver, which ensures a stable and invisible connection. This feature enriches the low-frequency range, making the system even more suitable for those who want an uncompromising cinematic experience. Every element has been designed to balance high-level performance with everyday practicality, maintaining low energy consumption in standby mode and with a strong focus on sustainability.

The KEF XIO is more than just a soundbar—it is a product that fuses advanced technology with contemporary design. With its discreet yet refined presence, it enhances the space it inhabits and becomes the centerpiece of a home multimedia system, uniting aesthetics and sound quality to transform every moment into an immersive experience.
