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. Each compact cabinet hides a dedicated 100W of amplification (70W LF + 30W HF) driving KEF’s Uni-Q® array, so vocals lock in, instruments snap into focus, and bass stays tight even at lively volumes. 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.
