The KEF XIO is a 5.1.2 channel soundbar with 12 class D amplifiers. It supports Dolby Atmos, DTS:X and Sony 360 Reality Audio. Its up-mixing converts mono and stereo sources into spatial audio.
Three Uni-Q MX drivers and two full range drivers handle the main channels. Four P185 LF drivers produce the bass. Each P185 has a racetrack shape (18cm/7" x 5cm/2") that keeps the soundbar slim while performing like a 4" LF driver. The drivers sit back-to-back in pairs to cancel force and reduce mechanical vibration. P-Flex technology and the VECO sensor, which monitors cone motion in real time to reduce distortion, are built into the bass drivers.
Intelligent Placement Technology calibrates the sound automatically based on the objects around the soundbar. It also offers adaptive shelf and wall modes. KEF's Music Integrity Engine (MIE) for Cinema handles multi-channel processing, virtualization and adaptive placement. A Dialogue Mode in the EQ presets enhances vocal frequencies and reduces background noise. The W2 Wireless Platform streams from Tidal, Amazon Music, Qobuz and Deezer, and from Spotify Connect, Tidal Connect and QPlay.
