KEF KC62
The biggest small subwoofer - with two 6.5" elements and 2*500w amplifier.
The KC62 is an incredibly compact subwoofer that offers deep and accurate bass for an immersive music, movie and gaming experience. It was created using innovative KEF technology, including the groundbreaking Uni-Core ™ technology. The football-sized KC62 features two 6.5-inch drivers driven by 1000W of Class D amplifiers.
Two 6.5-inch drivers are placed in a force-absorbing structure that eliminates the reactive forces caused by normal woofers. This setup keeps the KC62 perfectly balanced, so all you hear is deep, clean bass. 5 different presets, depending on the placement of the subwoofer, help the subwoofer to integrate perfectly with your equipment.

Wireless connection to the KEF XIO soundbar
The KEF KC62 subwoofer can connect wirelessly to the KEF XIO soundbar using a KEF KW2 RX receiver, sold separately. The receiver plugs into the subwoofer's expansion port. The transmitter is built into XIO.
- XIO supports up to two wireless subwoofers simultaneously. Each subwoofer requires its own KW2 RX receiver.
- With the firmware update released in November 2026, the same system can also use a pair of LSX II, LSX II LT or Coda W speakers as rear speakers. One additional KW2 RX is sufficient for the entire rear speaker pair.
- A rear speaker pair and two wireless subwoofers require three KW2 RX receivers in total.
Setup is handled in the KEF Connect app. Update XIO, its transmitter, the KW2 receivers and any rear speakers to the latest firmware. The XIO surround system requires a working home Wi-Fi network. Audio is transmitted wirelessly, but the subwoofer still needs a mains connection.
Use KW2 RX for the XIO connection. For wireless subwoofer connections in other audio systems, the KW1 Adapter Kit provides a transmitter and receiver.
The XIO soundbar, KW2 RX receivers and rear speakers are sold separately. See KEF's surround system setup guide (PDF).
