The perfect all-in-one high-performance wireless Hi-Fi speaker

Introducing the LS50 Wireless II from renowned British brand KEF. The original model was outstanding, but the LS50 Wireless II is even better – and in every respect. There’s improved sound, better usability and connectivity.

The Ultimate Wireless Hifi

More than just a high-performance loudspeaker, this compact all-in-one speaker system lets you stream your music from any source.

Out-of-the-box wireless compatibility with Chromecast, AirPlay 2, Spotify Connect and others alongside wired connections for your turntable, TV and games consoles, means the LS50 Wireless II offers you complete freedom to stream music with fantastic sound, all of the time. This exceptional loudspeaker can support streaming music files up to 24bit/96kHz resolution completely wirelessly, or you can connect the speakers for 24bit/192kHz resolution sound. Perfect for the Hi-Fi enthusiast who requires a flexible set-up or multi-room system.

When using the LS50 Wireless II with Airplay 2 and Chromecast there is the ability to stream to multiple speakers in your home simultaneously – a high-performance yet straightforward multiroom set-up!

12th generation Uni-Q & new technology

KEF developed the LS50 Wireless II’s built-in amplifiers in-house, and each tweeter is driven by a 100W class A/B amplifier to deliver a smooth performance, while the dedicated 280W class D amps power the mid/bass drivers to achieve controlled sound up to 108db that fills the room.

The LS50 Wireless II produces an accurate, immersive sound allowing you to enjoy music without distortion. This is thanks to the revolutionary Metamaterial Absorption Technology (MAT) and the 12th generation Uni-Q with MAT driver array, a revolutionary and highly complex maze-like structure developed using advanced simulation and analysis tools by KEF’s engineers. It absorbs 99% of unwanted sounds from the rear of the driver.

The curved baffle is precision-modelled around the Uni-Q 12th Generation with Metamaterial Absorption Technology driver and is capable of delivering outstanding, detailed sound with low diffraction. This ultimately results in the total elimination of distortion, giving the listener a more natural, accurate and pure sound. This life-like sound is dispersed evenly throughout the room and facilitates a beautifully delivered three-dimensional, wonderfully pure sound and a totally immersive audio experience.


Just like KEF’s LS50 Meta, every aspect of the LS50 Wireless II is engineered with acoustic benefits and design taking equal prominence and with precise attention to every detail.

Colour matched ports are located on the rear, and a top-mounted control panel is both functional and stylish. Available in three matte finishes plus a limited edition colour, the LS50 Wireless II is a modern and elegant piece of equipment to introduce to your home while also being supremely functional.
