What's in the box LSX II; Power cords; Interspeaker cable; Remote control; Quick Start Guide, warranty and safety information.

There has never been a better time to discover the joy of being able to hear all the detail in your favourite songs. KEF’s six decades of experience in acoustic excellence combined with constant innovation and the development of wireless technology has led to the creation of LSX II; a compact wireless Hi-Fi system that delivers pure, accurate sound, but with the compatibility and convenience of the very best wireless technology.

Much more than a simple upgrade from the award-winning original, LSX II combines class-leading sound with the all-encompassing W2 wireless platform from LS50 Wireless II. Connectivity options are further enhanced by the addition of both HDMI and USB-C, making this an ideal companion for both TV and desktop computer systems.

LSX II delivers room-filling, natural, accurate sound from any source thanks to the knowledge and experience of KEF’s talented engineers and the iconic Uni-Q driver array. Plus it has a contemporary design courtesy of famed industrial designer Michael Young, and is available in a choice of five stylish finishes.


Play all the music in the world.

At the digital heart of the LSX II sits the same cutting-edge W2 wireless platform that drives the mighty
LS50 Wireless II. This ensures that no matter how you like to listen to music, you can do so with the minimum of fuss and in pristine sound quality.

The KEF Connect app lets you stream Amazon Music, Qobuz, Tidal, Deezer, Internet Radio stations and podcasts. Apple AirPlay 2 and Google Chromecast seamlessly stream audio from compatible devices, whilst Bluetooth expands the options even further. You can use native apps to stream directly from Spotify Connect, Tidal and QPlay, and it is Roon Ready*. When using Airplay 2, Chromecast or Roon you can stream to multiple speakers, so you can play music all over your house. If that wasn’t enough, LSX II can also play your own private music collection from a compatible NAS drive or music server. Plus, audiophiles are covered with extensive file support up to 24bit/384kHz (PCM), DSD, and full MQA decoding.

Plug and play to TV and laptop

Alongside Wi-Fi and Bluetooth, LSX II also boasts a comprehensive collection of wired connections. These include HDMI ARC for seamless control using TV remote and a high-quality USB-C input which makes LSX II the perfect desktop system with your computer. There are also connections for your turntable, CD player, games console, and many other devices. And, if you demand your movies and music come with some extra bottom end, there’s a dedicated output so you can connect a KEF subwoofer for the bass you crave.


High-Fidelity sound.

The beauty of the two-speaker box approach is that music is given space to breathe and develop, creating a three-dimensional soundstage. The speakers appear to disappear, leaving you to enjoy the immersive performance that unfolds in front of you, drawing you into the experience. Each LSX II speaker uses a version of KEF 11th generation Uni-Q driver array specially designed for this loudspeaker. This signature technology acts as a point source, where the tweeter is placed at the precise acoustic centre of the woofer, recreating how sound is produced naturally. This design eliminates the traditional, tiny ‘sweet spot,’ instead delivering accurate, pristine sound to all listeners.

LSX II has a combined 200 Watts of system power. Both the tweeter and woofer are powered by their own dedicated amplifier to deliver room-filling sound in such compact cabinets.

Performance is further enhanced from the award-winning original by the Music Integrity Engine. The cutting-edge collection of bespoke Digital Signal Processing algorithms has just got an update. Optimised for the Uni-Q driver, the Music Integrity Engine enables LSX II to deliver a perfectly timed performance, for better clarity and a tighter, more accurate sound.


User-focused experience.

The KEF Connect app walks you through the set-up and controls the system and playback navigation, with intuitive sound settings so you can adjust LSX II to best suit your room. With its powerful Room EQ DSP, LSX II can be fine-tuned to your room and personal taste without the need for a degree in acoustic engineering. ‘Normal’ mode is designed to talk you through the process with easy questions – all you might need is a tape measure. For easy integration of a KEF subwoofer with LSX II, Room EQ includes subwoofer pre-sets for the best possible system performance. LSX II also comes with a host of other user-friendly features including volume settings, sensitivity adjustments, and the ability to select a source to wake it up when it comes on. You can choose to connect the speakers wirelessly with 24bit/48kHz resolution for a cable-free setup, or with the supplied cable for 24bit/96kHz resolution.

  3. 4/5


    The speakers are of exceptional quality. The sound is clear and loud without any distortion (not to my ears). For the price they’re a gem.

    The my get one star off because depending of your room setting and the electronic devices you have nearby the “slave” speaker the connection something cuts. It usually happens when a lot of devices are on (I for example have my computer nearby, and it uses WiFi).
