KEF XIO soundbar receives wireless surround speaker support

According to Audio Review Blog, KEF has released a software update for its XIO soundbar. The update allows compatible wireless speakers to be placed behind the listening position as true rear channels. According to StereoNET, the update is now available for use.

Until now, XIO created a virtual surround field through driver placement and signal processing. In the new configuration, rear channels come from physical speakers. The separately sold KW2 RX Receiver is used for the wireless connection between the primary rear speakers and the XIO. Setup and configuration is done through the KEF Connect application.

Which speakers can be used as rear channels?

• Via KW2 RX Receiver: LSX II, LSX II LT and Coda W can be integrated with the XIO according to KEF's specifications.
• Q1 2027: Support for LS60 Wireless and LS LUXE is indicated for this period.
• Subwoofers: KC62, KC92 and KUBE have been able to connect wirelessly since the XIO's launch.

What are the technical specifications of the XIO?

XIO is KEF's first soundbar, launched in 2025. The values provided in the source are as follows:

• Width 1,210 mm, weight 10.5 kg
• 12 drivers, 12 Class D amplifiers, total 820 W peak output power
• 5.1.2 channel configuration
• Coaxial Uni-Q MX driver, side-firing surround units and four oval woofers
• Dolby Atmos, DTS:X and Sony 360 Reality Audio support
• HDMI eARC, optical digital, Ethernet and RCA output for subwoofer

The price of the update is not specified in the source. The KW2 RX Receiver and supported speakers are sold separately, and their prices are also not included in the source. Those interested in comparing similar products can check the soundbar category.

Why does it matter?

XIO users and buyers now have a path from virtual surround to physical rear speakers. Since the KW2 RX Receiver and compatible speakers will need to be purchased separately, the total cost will vary depending on these additions.
