KEF LSX II – Discover the joy of music, movies and games

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

Much more than a simple upgrade from its award-winning predecessor, the KEF LSX II combines class-leading sound with the new W2 platform from the LS50 Wireless II, which offers better connectivity. Connectivity has been further enhanced with the addition of both HDMI and USB-C, making this an ideal companion for both TV and gaming.

How is the sound then? Here we’re pleased to say that the LSX II delivers both rich, natural and accurate sound from any source. A sound that’s only possible thanks to KEF’s talented engineers and the iconic Uni-Q unit. Plus, it features a contemporary design from renowned industrial designer Michael Young and is available in a choice of five stylish finishes.

Unlimited connectivity

With the LSX II, you can play all the music in the world you want. At the heart of this compact speaker you’ll find the same groundbreaking W2 platform that powers the LS50 Wireless II. It ensures you can listen to music exactly the way you prefer. Without affecting the 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, while Bluetooth gives you even more options. You can stream directly from Spotify Connect, Tidal and QPlay, and it’s even Roon Ready. When you use Airplay 2, Chromecast or Roon, you have the option to stream to multiple speakers, so you can play music throughout your home.

If that wasn’t enough, the LSX II can also play your own private music collection from a compatible NAS drive or music server. The wireless speaker even has extensive file support of up to 24bit/384kHz (PCM), DSD and full MQA reproduction.

Plug and play for TV and laptop

In addition to Wi-Fi and Bluetooth, the LSX II also boasts an extensive collection of wired connections. These include HDMI ARC for seamless control using the TV remote and a high-quality USB-C input, making the 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, there’s a dedicated output so you can connect a KEF subwoofer for the bass you crave.

True Hi-Fi quality performance

The advantage of two speakers is that the music has room to breathe and evolve, creating a three-dimensional soundscape. The speakers virtually disappear into the room, allowing you to immerse yourself in the music unfolding in front of you, drawing you into the experience.

Each LSX II speaker uses a version of the KEF 11th Generation Uni-Q driver array, designed specifically for that speaker. This signature technology acts as a point source, placing the tweeter at the precise acoustic centre of the bass unit and recreating how sound is naturally produced. This design eliminates the traditional small ‘sweet spot’ and instead delivers accurate, pristine sound to all listeners.

The 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 Music Integrity Engine. The pioneering collection of custom digital signal processing algorithms has just been updated. The Music Integrity Engine, optimised for the Uni-Q driver, enables the LSX II to deliver perfectly timed performance, for better clarity and tighter, more accurate sound.

A user-focused experience

The KEF Connect app guides you through setup and controls system and playback navigation with intuitive audio settings, so you can adjust the LSX II to best suit your room.

With its powerful Room EQ DSP, the LSX II can be fine-tuned to your room and personal tastes without the need for training in acoustic engineering. ‘Normal’ mode is designed to talk you through the process with easy questions – all you need is a tape measure. For easy integration of a KEF subwoofer with the LSX II, Room EQ includes subwoofer presets for the best possible system performance.

The 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 switched on. You can choose to connect the speakers wirelessly with 24bit/48kHz resolution for a cable-free setup, or with the included cable for 24bit/96kHz resolution.
