KEF LSX II Wireless HiFi Speakers - Cotton White Pair

Meet LSX II: a true, two-box wireless HiFi system that brings KEF’s reference-grade sound to desktops, bookshelves, and small living rooms - without the rack of separates.

With HDMI ARC and USB-C you can upgrade TV and laptop audio in one move; with AirPlay 2, Google Cast, Bluetooth 5.0, Roon Ready, and high-res network streaming up to 24-bit/384 kHz, your music simply arrives the best way it can. Finished in premium, fabric-wrapped cabinets by designer Michael Young and available in four curated colors - Amber Haze, Cotton White, Carbon Black, and Soundwave - LSX II looks as refined as it sounds.
