KEF LSX II Wireless HiFi Speaker System – Carbon Black (Pair)
The KEF LSX II is an active stereo loudspeaker system supplied as a pair, with amplification and network streaming built into the speakers. Its Uni-Q array places a 19 mm aluminium-dome tweeter at the centre of a 115 mm bass/midrange cone, providing a compact alternative to separate hi-fi components. HDMI ARC makes television connection straightforward, while USB-C, optical and analogue inputs accommodate computers and other sources. AirPlay 2, Google Cast and Bluetooth add wireless listening options, subject to service and device compatibility. Both speakers need mains power; wireless communication between them does not make the system battery-operated. The supplied interspeaker cable offers a wired alternative and increases internal signal resolution from 24-bit/48 kHz to 24-bit/96 kHz. A separate amplifier is unnecessary, while stands, wall brackets and any optional subwoofer should not be assumed to be included.
