PerformanceMost accurate, immersive soundLS50 Wireless II melts away, leaving you to enjoy the music. Revolutionary Metamaterial Absorption Technology eliminates distortion for a purer, more natural sound, while our 12th generation Uni-Q with MAT driver array delivers three-dimensional, wonderfully revealing sound anywhere in the room.

Music Integrity EngineAll 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 powerThe 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.

DesignAttention to every detailEvery 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.
