Features
Connectivity
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 rendering.
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.
Performance
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.
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 cuttingedge 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-centred
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.
Design
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 world of industrial design. Famed for his sophisticated take on minimalism, Young’s signature is a smart, pared down aesthetic that perfectly suits LSX II’s requirement to deliver pristine, accurate sound while also looking incredible. 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. LSX II also has neat mounting inserts, for secure placement on the P1 desk pad, S1 floor stand or B1 wall bracket.
Statement finishes
LSX II is available in a choice of five finishes: Mineral White and Lava Red models finished with satin and gloss spray, 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.
