Product description
The active, fully wireless version of KEF's iconic LS50: the 12th-gen Uni-Q array (25 mm MAT tweeter coaxial with a 130 mm aluminium mid/bass) driven by 380 W of bi-amplification per cabinet. Wi-Fi streaming with AirPlay 2, Chromecast, Roon and Spotify/TIDAL/Qobuz Connect plus HDMI eARC make it a complete two-piece hi-fi system — a benchmark active stand-mount that needs no separate amp.
