This all-in-one speaker system is in its second generation: upgraded to deliver a more balanced sound in higher resolution with all-inclusive connectivity. Simply stream anything including AirPlay 2, Chromecast, Spotify and Tidal, or seamlessly connect the LSX II to your laptop, TV and many other devices.
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 dedicated amplifiers 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. Feel the performance.
With two speakers positioned apart from each other, the LSX II creates a three-dimensional soundstage of true stereo sound, bringing your favourite tunes to life for a listening experience that a one-box speaker cannot come close to.
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.
Sit anywhere, hear every detail
Uni-Q® technology is the building block of KEF signature sound. Designed to perform at its best in LSX II, the Uni-Q driver array acts as a single point source to enlarge the ‘sweet spot’ and disperses sound more evenly, allowing everyone sitting at different spots in the room to experience the same natural, detailed sound.
Connectivity
All the music in the world
The advanced W2 wireless platform of LSX II 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.
Transform your entertainment experience
Perfect partner for… everything
Sound plays a big role in your home entertainment experience and LSX II elevates the total experience with high-fidelity sound. Fully loaded with wired and wireless connections, LSX II is perfect for music, gaming, TV, movies and even your personal working space.
Plug and play to TV, laptop and more
With LSX II, you can connect your TV with HDMI ARC, your laptop with USB-C, and even a turntable, CD player or games console. If you demand your movies and music come with extra bass, there’s a dedicated output to connect a KEF subwoofer.
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.
User-centred
Instant control in your palm
The KEF Connect app walks you through a 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.
Personalised listening experience
Simple, subtle yet powerful EQ settings allow you to fine-tune LSX II to best suit your room or your personal taste. The only thing you might need is a tape measure.
Design
Designed to fit into different spaces
LSX II delivers high-fidelity sound while it is compact enough to fit comfortably into any setting. It is also incredibly flexible with its dedicated accessories including S1 floor stands, P1 desk pads and B1 wall brackets, so you can place the speakers on a bookshelf or desktop, pair them with the floor stand or even attach them to the wall.
Statement finishes
Every 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. It is available in five finishes: matte satin Mineral White and high-gloss Lava Red, plus Carbon Black, Cobalt Blue and the Soundwave by Terence Conran Edition clad in a specially designed fabric from Danish textile designer, Kvadrat.
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.
Soundwave by Terence Conran
The Soundwave by Terence Conran Edition unites two of Britain’s most celebrated names in a single, unique design. The Uni-Q drivers and rear port are finished in Conran’s signature blue, while a ‘soundwave’ pattern is woven into the unique Kvadrat fabric for a true statement of the meeting of acoustics and design.
Simplicity, beauty and functionality are the solid foundations of good design but I always think a magic ingredient can raise the whole look or mood of a product.
SIR TERENCE CONRAN
Made for each other
LSX II Soundwave by Terence Conran Edition unites two of Britain’s most celebrated names in one unique design. This fusion of Conran’s renowned aesthetic and the legendary KEF sound could not have a more fitting home than the perfectly balanced form and function of the LSX II Soundwave.
A new wave in sound
The Conran Soundwave pattern is woven in to fabric from Danish textile designer Kvadrat. Award-winning technology inside includes KEF’s Uni-Q® driver array that delivers incredibly detailed stereo imaging. Fully wireless, LSX II Soundwave takes just minutes to set up and start connecting to a wide array of music sources.
The people’s designer
In a long and celebrated career, Terence Conran didn’t merely change the rules of design, he created a whole new game. After studying textile design, he set up a workshop in the East End of London in the 1950s and in the years since, the Conran Consultancy has stood at the vanguard of design democratisation.
Fuelled by a passion for the modern movement and its benefit to society, Sir Terence’s astonishing breadth of work, encompasses everything from furniture to product design, restaurants, architecture, fabric, fashion, retail and literature.
