Performance

Most accurate, immersive sound

Metamaterial Absorption Technology

A truly revolutionary tool in the KEF acoustic armoury, Metamaterial Absorption Technology (MAT) is a highly complex maze-like structure that absorbs 99% of the unwanted sound from the rear of the driver, eliminating the resulting distortion and providing purer, more natural sound.

Every spot is the sweet spot

12th generation Uni-Q with MAT

Even beyond the flawless musical performance, LS50 Wireless II is a breeze to set up thanks to the KEF Connect app. It is intuitive to use with any source in your home, and it allows simple over-the-air firmware updates that bring you new and improved features with the minimum of fuss.

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.
 

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 colour for you

LS50 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.

Design by Simon Davies and KEF Industrial Design Team

Simon Davies led the KEF Industrial Design Team from 2000 through to 2018. He was responsible for key product designs including LS50 and LS50 Wireless, The Reference and R Series.

What's new

Owners of the LS50 Wireless may be wondering what’s new? The answer: pretty much everything. The original was fantastic, but LS50 Wireless II is better in every respect, with improved sound, better connectivity and usability thanks to the brand new W2 wireless platform.
