Product details

KEF’s LSX II LT is a compact stereo wireless music system with dedicated Class D amplification for each driver. Its Uni-Q array places the 19 mm aluminium tweeter at the centre of a 115 mm magnesium/aluminium mid/bass cone, helping distribute sound evenly across the listening area.

Music, television and desktop audio

AirPlay 2, Google Cast, Bluetooth 5.0 and UPnP support music playback from compatible devices and services. HDMI ARC connects a television, USB-C accepts computer audio and Toslink accommodates an optical source. Spotify Connect, Tidal Connect and other services integrate through the network platform, subject to regional availability.

Simple setup and room adjustment

The KEF Connect app provides setup and room-oriented EQ. A proprietary USB-C interspeaker cable carries power and audio to the secondary speaker, so only the primary speaker needs a mains connection. All sources are resampled to 96 kHz/24-bit between speakers. An RCA subwoofer output extends system flexibility. Sage Green, Graphite Grey and Stone White finishes are available; optional S1 stands, P1 desk pads and a longer C-Link cable are sold separately.
