Product details
KEF XIO is a 5.1.2-channel soundbar for TV, films, games and music. It decodes Dolby Atmos, DTS:X and Sony 360 Reality Audio, with upward-firing drivers for height effects. Twelve Class D amplifier channels power its Uni-Q MX, full-range and P185 bass drivers.
Drivers and room adjustment
KEF’s compact Uni-Q MX design places the tweeter at the centre of the midrange driver. Four low-profile P185 bass drivers use Velocity Control Technology to monitor and correct cone movement. KEF’s Cinema Music Integrity Engine handles spatial processing, while Intelligent Placement Technology adjusts the soundbar’s EQ to account for nearby surfaces. Dialogue and Night modes help tailor playback to the room and listening level.
TV, streaming and system expansion
Connect a TV over HDMI eARC or optical. Bluetooth 5.3 supports direct playback, while Wi-Fi and Ethernet provide access to network streaming via KEF Connect, AirPlay, Google Cast and supported music services. The bar can sit on a cabinet or mount on the wall with the included kit. An active subwoofer can connect via RCA or wirelessly using the optional KW2.
Optional wireless rear surrounds with LSX II, LSX II LT or Coda W via a separately sold KW2 RX Receiver. Requires XIO firmware 1.5.160 or later, transmitter and KW2 firmware 2.0.0.0 or later, updated speaker firmware and KEF Connect 1.32.0 or later.
