Most accurate, immersive sound
- LS50 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 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.
- 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.
Attention to every detail
- 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.
