KEF LS50W MKII Wireless Speakers (Pair), Carbon Black with Stands Overview
The KEF LS50W MKII are What Hi-Fi? award-winning wireless speakers, with their 12th-generation Uni-Q driver array enabling a room-filling, three-dimensional sound image and wide 'sweet spot'. This setup is enhanced by Metamaterial Absorption Technology (MAT) which effortlessly reduces any distortion, creating a live concert-like atmosphere in your own living space. KEF's bespoke Music Integrity Engine, a collection of custom Digital Signal Processing algorithms, eliminates timing errors to offer excellent imaging and crossover. Additionally, you can expect incredible audio thanks to the two built-in amplifiers powering each driver individually, capable of delivering a total power output of 380W.
The KEF Connect app adds a layer of convenience, granting full speaker control and support for major streaming platforms such as Spotify, TIDAL, and Apple Music. Using Bluetooth, these speakers can wirelessly connect to your smart devices and stream music up to 24bit/96kHz audio. Taking things one step further, MQA and DSD help produce accurate sound reproduction that's as close to the original recording as possible. The LS50W MKII is even Roon Ready, so you can play your favourite playlists and albums throughout multiple rooms in your home, contributing to an audiophile listening experience that follows you wherever you're listening.
These wireless speakers also include two KEF S2 Speaker Stands, helping to increase sound dispersion for immersive listening.

Exceptional Sounds
At the heart of the LS50W MKII speakers is their 12th-generation Uni-Q driver array. This KEF-exclusive setup places the 25mm tweeter in the acoustic centre of the midrange cone, creating an immersive, room-wide sound that is elevated further by the powerful 5.25-inch driver. To ensure optimal sound clarity, Metamaterial Absorption Technology (MAT) absorbs the rear wave of the tweeter. This extinguishes 99% of any unwanted sound reflections, resulting in a world-class high-frequency response.
Robust Audio
The LS50W MKIIs are fitted with a Music Integrity Engine, which uses Digital Signal Processing (DSP) to optimise the audio in real time. The result is a balanced, well-timed sound with excellent dispersion so you can hear every lyric in pristine quality. These active speakers also feature a combination of a 100W class A/B and a 280W class D amplifier to independently power the tweeter and mid/bass driver respectively. This bi-amplification technique allows for a more dynamic sound output across all music genres.
Smooth Wireless Listening
These adaptable speakers are also designed to cater to the modern listening habits of audiophiles. With built-in Bluetooth, you can effortlessly stream your playlists, albums and podcasts in commanding 24bit/96kHz resolution. There is even full support for Master Quality Authenticated (MQA) and Direct Stream Digital (DSD), so you can relish studio-quality audio. But it doesn't stop there! When using AirPlay 2, Chromecast or Roon you can stream to multiple speakers, enabling you to play music all over your house.
Effortless Connectivity and Control
As well as its wireless capabilities, the two LS50W MKII speakers can be connected using the supplied cable for 24bit/192kHz audio. The optical, coaxial, and HDMI eARC inputs will ensure smooth connectivity to all your hi-fi separates, with the subwoofer output allowing you to expand your speaker system to a 2.1 setup. Moreover, the dedicated KEF Connect app gives you complete control over your musical experience. You can easily play/pause songs, alter audio settings, and access streaming platforms such as Spotify, TIDAL, Apple Music, and Qobuz.
