HiFi enthusiast

LS50 Wireless II has audiophiles covered with support for streaming music files up to 24bit/384kHz, as well as MQA, DSD, and Roon Ready. These features mean that even the experienced hifi enthusiast will marvel at this exceptional loudspeaker’s ability.

Music Integrity Engine

All aspects of the LS50 Wireless II’s performance is aided by KEF’s bespoke Music Integrity Engine. This collection of bespoke Digital Signal Processing algorithms is optimised for the Uni-Q driver, enabling it to deliver a perfectly timed performance, for better imaging and a tighter sound.

Plentiful power

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.

Seamless home integration

LS50 Wireless II is more than a high-fidelity speaker system - it is designed to enhance your everyday life. Seamlessly integrate LS50 Wireless II into your smart home to browse and play music, select sources, or use controls such as play, pause, and adjust the volume via your smart home app or control interface.

Wired or wireless connectivity

You can choose to operate LS50 Wireless II completely wirelessly at 24bit/96kHz resolution for a completely clutter-free set up, or you can connect the two speakers with the supplied cable for 24bit/192kHz resolution sound.
