The compact wireless system that brings true hi-fi sound to every room
The KEF LSX II are compact active wireless speakers designed to offer high-quality listening in modern homes, studies, living rooms and advanced desktop set-ups. This stereo system combines elegance, ease of use and a complete technical specification, making it an ideal solution for those who want a refined system without resorting to separate electronics. Thanks to KEF's acoustic design and the bookshelf format, the LSX II manage to combine a small footprint with credible performance, and a carefully judged, versatile sonic character.
Uni-Q technology and dedicated amplification for a precise, engaging sound
At the centre of the system is the 11th-generation Uni-Q driver, with a 19 mm tweeter and a 115 mm mid-bass unit in each speaker, designed to improve spatial coherence and the precision of the sound image. The KEF LSX II also include a dedicated amplification section with 70 W in Class D for the bass/midrange and 30 W in Class D for the high frequencies in each speaker, allowing accurate control of the signal and an energetic, detailed sound. The declared frequency response reaches 49 Hz – 47 kHz as range and 54 Hz – 28 kHz at ±3 dB, with a maximum sound pressure level of 102 dB.
High-resolution streaming, TV and desktop: a truly complete system
The KEF LSX II support streaming up to 24 bit / 384 kHz and provide an extremely complete platform with AirPlay 2, Google Cast, Spotify, Tidal and multiroom compatibility, making them well suited both to streamed music and to simple, immediate everyday use. On the rear they offer very versatile connections, including HDMI ARC and USB-C, in addition to the other digital and network inputs provided by the system, so that they can be easily integrated with TVs, computers and modern sources. For this reason they are one of the most interesting solutions for those looking for a compact yet technologically advanced wireless hi-fi system.
