LS50 Wireless II is more than a high-performance loudspeaker; it’s the perfect all-in-one speaker system, streaming from any source thanks to wireless compatibility with AirPlay 2, Chromecast and more, plus wired connections for your TV, games console and turntable. Great sound, no strings attached. KEF's 12 generation Uni-Q with Metamaterial Absorption Technology (MAT ™) delivers reduced coloration, less distortion, and a sound that is more transparent and life-like than previously possible.
