The award-winning LS50 Wireless II from KEF is more than a high performance loudspeaker, its the perfect all-in-one speaker system with new, innovative technology giving you superior sound so clear, revealing every detail of your favourite music, as though the artist is there with you in the room.

Featuring Metamaterial Absorption Technology (MAT), a truly revolutionary tool in the KEF acoustic armoury. Its a highly complex maze-like structure that absorbs 99% of the unwanted sound from the rear of the driver, eliminating the resulting distortion and providing purer, more natural sound. The built-in amplifiers have been developed in-house by KEF. Each tweeter is driven by a 100W class A/B amplifier that delivers a smooth, incredibly detailed treble performance. Dedicated 280W class D amplifiers power the mid/bass drivers, for room-filling, controlled sound up to 108db.

No matter how you stream your music, LS50 Wireless II has you covered. You can stream directly from the Spotify native app with Spotify Connect. With the KEF Connect app you can also stream Tidal, Amazon Music, Qobuz and Deezer or tune in to internet radio and podcasts. Out-of-the-box wireless compatibility with AirPlay 2, Google Chromecast and more means you can stream to multiple speakers around your home at the same time and by using multiple LS50 Wireless II speakers, you can have a simple, high-performance multiroom system. There are wired connections for your TV, turntable, CD player and games console.

The brand-new dedicated KEF Connect app controls LS50 Wireless II on a day-to-day basis, including intuitive sound settings so you can tune the sound to your own personal tastes. You can even select your favourite source to wake up LS50 Wireless II whenever it comes on, allowing you immediate access to the best sound.

Every aspect of LS50 Wireless II has been considered for acoustic benefits and from a design perspective. The low-diffraction, curved baffle is precision modelled around the Uni-Q driver, while eye-catching heat sinks and colour-matched ports are located on the well-equipped rear. The top-mounted control panel is designed to be stylish and functional.
