User-Centred -Â you be you

Personalised listening experience

Simple multiroom system
When using LS50 Wireless II with Airplay 2, Chromecast or Roon you can stream to multiple speakers around your home at the same time. By using multiple LS50 Wireless II speakers, you can have a simple, high-performance multiroom system.
Performance - The 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 IIâs performance is aided by KEFâs 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.
Design - 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.
The perfect colourÂ
LS50Â Wireless II is available in three matte finishes, carbon black, titanium grey, and mineral white, as well as a Crimson Red Special Edition. All the colour options are mirrored on both the drive units and the rear-facing port. The top-mounted control panel is designed to be stylish and functional.
