The KEF XIO is KEF’s flagship all-in-one high-end soundbar, bringing audiophile-grade acoustic engineering into a modern, minimalist home theater form factor. It targets users who want native spatial audio and music performance without setting up a traditional multi-speaker AV receiver system. Audio & Performance Acoustic Architecture: A standalone 5.1.2 channel setup powered by 12 Class D amplifiers delivering up to 820W total output. Uni-Q MX Driver Array: KEF's signature driver places the tweeter in the acoustic center of the midrange cone, broadening the "sweet spot" across the room. P185 Drivers & VECO: Four low-frequency drivers featuring Velocity Control Technology produce tight, deep bass without requiring an immediate external subwoofer. Spatial Audio: Native decoding for Dolby Atmos, DTS:X, and Sony 360 Reality Audio, supported by KEF’s Music Integrity Engine (MIE) to upmix 2-channel sound. Smart Features & Tuning Intelligent Placement Technology (IPT): Automatically senses nearby surfaces (e.g., wall-mounted vs. table-mounted) and adjusts EQ balance to optimize room response. KEF Connect & Streaming: Integrates Apple AirPlay, Chromecast, Spotify Connect, TIDAL, Qobuz, and Amazon Music, supporting high-res playback up to 24-bit/384kHz. Connectivity Inputs: HDMI eARC, Optical, USB-C, and RJ45 Ethernet. Expandability: Includes RCA and wireless subwoofer output connections, plus support for wireless surround speakers.
