Wireless Connection From XIO Soundbar to Any Subwoofer

The KEF KW2 RX Receiver enables seamless wireless connectivity between the XIO Soundbar and any compatible subwoofer. Designed for effortless integration, KW2 ensures clean installation, flexible placement, and stable high‑quality audio transmission   all without the limitations of cables.


Flexible Subwoofer Placement

KW2 allows your subwoofer to be positioned anywhere in the room within a 15m line‑of‑sight range from the XIO Soundbar. This flexibility ensures optimal bass performance without compromising room layout or aesthetics.

Wireless Connection With KEF Subwoofers

Featuring four connector pins, KW2 plugs directly into the back of KEF subwoofers for a secure, cable‑free connection. It works flawlessly with:

  • KC62
  • KC92
  • KF92
  • Kube Series

This ensures uninterrupted wireless transmission and a clean, minimalist setup.

Aux/Optical Combo Output for Third‑Party Subwoofers

KW2 also supports non‑KEF subwoofers. Simply power the receiver via USB‑C and connect using:

  • 3.5mm analogue output, or
  • TOSLINK optical output

The included cover conceals the exposed connector pins for a tidy finish.
