LSX II
The Definitive Compact Wireless HiFi.
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 innovation in acoustic excellence combined with 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 KEF W2 wireless platform for AirPlay 2, Chromecast, Spotify, Tidal, and more. 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.

PERFORMANCE
High-Fidelity sound
KEF is obsessed with bringing a superior listening experience whatever the size of the speaker. With built-in support of streaming up to 24bit/384kHz and a dedicated amplifier inside each speaker, LSX II offers the highest quality sound in its size and makes high-fidelity sound accessible to a wider range of listeners.
Stereo performance
With two speakers positioned apart from each other, the LSX II creates a three-dimensional sound stage of true stereo sound that brings your favourite tunes to life. It’s a listening experience that a one-box speaker cannot come close to.
The beauty of the two-speaker box approach is that music is given space to breathe and develop, creating stereo imaging, where instruments can be picked out in space. The speakers appear to disappear, leaving you to enjoy the immersive performance that unfolds in front of you, drawing you into the experience.
Sit anywhere, hear every detail
Uni-Q® technology is the building block of KEF signature sound.
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,’ allowing everyone sitting at different spots in the room to experience natural, detailed sound.
Small speakers, big sound
LSX II is upgraded from the first generation to deliver a more balanced sound in higher resolution. It is precisely tuned with enhancement on the bespoke Digital Signal Processing algorithms in the Music Integrity Engine (MIE™). Optimised for the Uni-Q driver array, the MIE ensures a perfectly timed performance with clear, accurate and more balanced sound.
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 from such compact cabinets.
CONNECTIVITY
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 Tidal, Amazon Music, 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 and Tidal, and LSX II 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 rendering.
Plug and play to TV, computer, and more
Alongside Wi-Fi and Bluetooth, LSX II also boasts a comprehensive collection of wired connections.
These include HDMI ARC for seamless control using your original 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.
Same music, same enjoyment for every room
When partnered with other sets of LS Wireless speaker systems including LSX II, LS50 Wireless II and LS60 Wireless, you can use Airplay 2, Chromecast or Roon to fill your entire house with music. It’s perfect for parties where everyone in different rooms can enjoy the same playlist.
USABILITY
Instant control in your palm
The KEF Connect app for iOS and Android walks you through simple setup and gives you complete control of what you play on the LSX II. 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.
Wireless or wired
LSX II offers you the choice of wireless interspeaker connectivity or wired connection to maximise performance. 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.
Personalised listening experience
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.
DESIGN
Statement finishes
LSX II is now available in a choice of six finishes: Mineral White and Lava Red models are finished with satin and gloss spray respectively, while Carbon Black and Cobalt Blue are clad in a specially designed fabric from Danish contemporary textile designer, Kvadrat.
The Soundwave by Terence Conran Edition sees the ‘soundwave’ pattern woven into the same unique fabric for a true statement of the meeting of acoustics and design.
Finally, as a personal favourite of the LSX II designer, the new Olive Green finish also features the printed signature of Michael Young.
Sound by KEF. Design by Michael Young.
The aesthetic design of LSX II comes courtesy of Michael Young, one of the leading lights in the industrial design world. Famed for his sophisticated take on minimalism, Young’s smart, pared down aesthetic perfectly strikes the ideal balance between form and function on the LSX II.
Every single aspect of LSX II is carefully considered, with an elegant rear control panel and subtle design accents such as colour-matched finishes on the Uni-Q driver and ports
