Kef LS50 Wireless II Speaker System

£2,249.00

Brand Kef

The new Kef LS50 Wireless II Speaker System incorporates Kef's new Metamaterial Absorption Technology which is a highly complex maze-like structure that eliminates unwanted sound from the rear of driver, resulting in a purer, more natural performance.  KEF's trademark Uni-Q driver has also been redesigned and improved, incorporating the new Meta technology, powered by a new 280W Class D amplifier, and a new 100W class A/B amplifier powering the tweeter. 

The Kef LS50 Wireless II will streaming music files up to 24bit/384kHz, as well as MQA Decoding and DSD256 for truly high-resolution audio playback. LS50 Wireless II is also Roon Ready certified. AirPlay 2 and Google Chromecast seamlessly connects your compatible Apple or Android device, whilst Bluetooth expands the options even further. With the KEF Connect app, you can stream Tidal, Amazon Music, Qobuz, Deezer, Internet Radio stations and podcasts. You can also stream directly from the native app with Spotify Connect. There are also wired connections for your TV, turntable, CD player and games console, via the HDMI, analogue, optical and coaxial sockets. 

LS50 Wireless II is available in three matte finishes, carbon black, titanium grey, and mineral white, as well as a Crimson Red Special Edition. All the colour options are mirrored on both the drive units and the rear-facing port. The top-mounted control panel is designed to be stylish and functional.
