KEF LSX II Wireless Speakers
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 six stylish finishes.
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.
Seamless Home Integration: LSX II is more than a high-fidelity speaker system - it is designed to enhance your everyday life. Seamlessly integrate LSX II into your smart home to browse and play music, select sources, or use controls such as play, pause, and adjust the volume via your smart home app or control interface.
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's 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.
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 six finishes: Mineral White and Lava Red models finished with satin and gloss spray, while Carbon Black, Cobalt Blue, and Olive Green 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.
KEF LSX II Review
"The KEF LSX IIs are wireless marvels. There is no tether necessary to connect the primary and secondary speakers, although using the tether bumps resolution from 24-bit/48kHz up to 24-bit/192kHz. The KEFs sport sleek, gorgeous looks, including real cloth wrappings that feel almost luxurious. They're powered by a 70W Class D amp for the mid and bass driver, and a 30W amp for the tweeter. The inputs are simple: Bluetooth, Wi-Fi streaming, one optical connection, and a 3.5mm analog AUX port. Their small size belies their huge sound: Bass is big and tight when adjusted via the Control app, and the midrange is a delight. For anyone looking for an all-in-one solution in a small package without sacrificing sound quality, the KEF LSX IIs are highly recommended."

Our Take On The KEF LSX II
Just like its bigger brother, it doesn't get any simpler than this. Take a few minutes to set up a pair of LSX II's and that is your whole system, nothing more to add. It almost seems like a trick. Surely you need something else? But no, if you want to stream music from a major streaming service then a pair of these plugged into power and connected to your Wi-Fi is everything you need to enjoy almost all the music in the world. Oh, and if you'd like to invest in an HDMI lead you can also plug your TV in for the simplest, smallest stereo AV system imaginable. A compact, beautifully designed and finished home friendly streaming system for the modern lifestyle. Nice one KEF.
