 LS60 Wireless Floor Standing Speakers

Obsessed with sound quality and committed to bringing a superior listening experience, KEF has been pioneering innovative acoustic engineering since 1961. Celebrating 60 years of innovation in technology, performance and design, LS60 Wireless is our vision of high-fidelity for the future. As KEF’s first wireless tower stereo system, LS60 Wireless aims to bring high-fidelity sound to more people in their homes.
For LS60 Wireless KEF’s engineers have seamlessly combined elements of the iconic Blade’s Single Apparent Source technology, a specially designed 12th Generation Uni-Q driver array, the revolutionary Metamaterial Absorption Technology1 (MATTM), Uni-Core bass drivers and much more besides. The final pieces of the jigsaw are the forward-thinking W2 wireless platform and a wide range of wired inputs, ensuring LS60 Wireless can play all major music services and supports all major audio sources.
The combination of all KEF’s key technologies delivers superlative acoustic performance and allows LS60 Wireless to be incredibly slim with highly distinctive look. The ultra slim profile of the speakers makes room placement easier for different spaces within people’s homes.

PERFORMANCE

Celebrating 60 years of acoustic innovation
LS60 Wireless is the world’s first Single Apparent Source wireless system. The unique Single Apparent Source technology is adapted from KEF’s flagship Blade speaker. By precisely placing the LF drivers equidistant around the Uni-Q driver array, it achieves the acoustic ideal of a point source where low, mid and high frequencies radiate from one single point. The result is noticeably more precise imaging and highly accurate sound across a wider listening area.
At the heart of LS60 Wireless’ Single Apparent Source design sits the remarkable 12th Generation Uni-Q with MAT driver array. Specially designed to perform at its best in the LS60 Wireless, this cutting-edge Uni-Q boasts a host of refinements including a tweeter gap damper and new Z-Flex surround that ensure a near-perfect transition of sound from the speaker into the room. With the MAT that acts as an acoustic black hole, 99% of the unwanted sound that comes from the rear of the tweeter is absorbed, eliminating the resulting distortion and providing a purer, more natural acoustic performance. Together, these innovations and refinements deliver a super-wide sweet spot, uncannily natural sound with vanishingly low distortion.
The slim profile of the speakers and close positioning of the drivers in the Single Apparent Source configuration call for a novel approach to bass driver design. As a result, LS60 Wireless features 2 pairs of Uni-Core driver arrays, first found on the KC62 subwoofer, maximising bass performance while minimising space. KEF’s P-Flex and Smart Distortion Control Technology also play their parts, ensuring that the low frequency performance is as balanced and detailed as the audio derived from the Uni-Q driver array. In addition, the bass drivers are mounted back-to-back as force-cancelling arrangement, cabinet vibration is practically eliminated.
Smart and powerful
The Music Integrity Engine brings together the Single Apparent Source configuration and other KEF acoustic technologies, allowing them to work closely, and elevating the impact of each. The brain behind most of KEF’s wireless speakers, Music Integrity Engine offers a suite of bespoke Digital Signal Processing algorithms (DSPs), enabling it to deliver a perfectly timed performance with better imaging and a tighter sound. The Music Integrity Engine for LS60 Wireless features low-frequency phase correction. This new feature does more than ensuring perfect timed performance, it delivers pinpoint timing exactly as if you were listening to the original sound.
The LS60 Wireless also has power in abundance, with a highly optimised mixture of bespoke Class AB and Class D amplification delivering a combined 1400 Watts of audiophile-grade power, with amplifiers dedicated to high, medium and low frequencies within each speaker. This power is smartly managed, so each driver receives precisely what it needs to perform at its best, meaning LS60 Wireless is capable of a beautifully balanced performance at any volume level.
LS60 Wireless also offers you the choice of wired or wireless interspeaker connectivity. You can choose a wired connection with resolution up to 24bit/192kHz or use KEF’s low-latency intelligent wireless interspeaker connection, which provides exceptionally reliable cable-free listening up to 24bit/96kHz.

You can use native apps to stream directly from Spotify Connect, Tidal and QPlay, and it is Roon Ready. LS60 Wireless also supports the streaming of PCM files up to 24bit/384kHz, as well as MQA decoding and DSD.
The connection options don’t stop there, LS60 Wireless also supports all your wired sources whether you love to listen to vinyl records on your turntable or want to get the best possible sound from your CD player and games console. There’s also an HDMI (eARC) connection for a high-quality link up with your TV, and a dedicated output on each of the two speakers for the addition of one or two KEF subwoofers.

USABILITY

Effortless control
The KEF Connect app walks you through the set-up and features intuitive sound settings so you can finetune LS60 Wireless to best suit your room; there are normal and expert modes so you can get the best performance regardless of your knowledge of acoustics. The app first lets you effortlessly connect the LS60 Wireless to your home network, before providing control over every aspect of the performance.

DESIGN

Impossibly slim. Made possible.
The LS60 Wireless’ extremely slim design is only possible because of the advanced technologies contained within the sleek cabinet. The product of a joint design by renowned designer Michael Young and the KEF product design team, LS60 Wireless is an exceptionally elegant loudspeaker that can fit effortlessly into a wider range of living spaces, both because of its looks and thanks to a broader range of placement possibilities.
Finally, LS60 Wireless is available in three elegant matte finishes: Titanium Grey, Mineral White and Royal Blue. This colour scheme is designed to fulfil two types of approach to interior design. Titanium Grey and Mineral white are made to be integrated and blended into various spaces while Royal Blue, a more striking finish, is perfect for people who are determined to make a statement. All of the finishes feature tonematched drive units and detailing to round off a truly exceptional loudspeaker.
