“An innovative and entertaining sequel”

“As a new product following in the footsteps of such a huge success, the KEF LS50 Wireless IIs arrive with a world of expectation on their shoulders – but they well and truly meet those expectations. Make no mistake, this is a sequel of rare quality.”

AV Forums – Highly Recommended

“All the engineering cleverness has been corralled into something fundamentally usable day to day and that obviates some of the demands that the passive version makes on commensurately priced equipment.”

The multi-award winning LS50 Wireless speaker system set the bar high for high-performance wireless speakers, and in the same spirit of invention and innovation that created the original, the LS50 Wireless II is much more than just a new generation.

The result of three years intensive research and development, the new KEF LS50 Wireless II is a fully active wireless stereo speaker system that delivers pristine, KEF signature sound coupled with great usability and high-performance wireless capability. LS50 Wireless II has been built on a whole new acoustic platform, the LS50 Meta passive loudspeakers, while the brand-new wireless platform has been engineered from the ground up. Active electronics, Digital Signal Processing (DSP), wireless streaming platform and the new KEF Connect app all combine to set a new benchmark of class-leading acoustic and user experience.

All The Music, All The Time

The new wireless platform that sits at the digital heart of the LS50 Wireless II ensures that no matter how you like to listen to your music, you will be able to do so with the minimum of fuss and in fantastic sound quality. LS50 Wireless II gives you direct access to your favourite music services, including Spotify (via Spotify Connect), Tidal, Amazon Music, Qobuz and Deezer. You can even tune in to Internet Radio Stations and catch up on the latest podcasts through the KEF Connect app. AirPlay 2 and Google Chromecast seamlessly connects your compatible Apple or Android device, whilst Bluetooth expands the options even further. There are also wired connections for your TV, turntable, CD player and games console, via the HDMI, analogue, optical and coaxial inputs. LS50 Wireless II has audiophiles covered with support for streaming music files up to 24bit/384kHz, as well as MQA Decoding, DSD256, and Roon Ready. These features mean that even the experienced hi-fi enthusiast will marvel at this exceptional loudspeaker’s ability; LS50 Wireless II really does offer something to everybody

Let You Be You

Even beyond the flawless musical performance, the LS50 Wireless II speaker system is a breeze to set up, intuitive to use and offers over-the-air firmware updates for bringing you new and improved features with the minimum of fuss. You can choose to connect the speakers with the supplied cable (24bit/192kHz resolution) or wirelessly (with 24bit/96kHz resolution) for a completely clutter-free set up. You can even select your favourite source to wake up LS50 Wireless II whenever it comes on, giving you immediate access to your favourite source. Plus, when using AirPlay 2, Chromecast or ROON you can stream to multiple speakers, so you can play music all over your house. The brand-new dedicated KEF Connect app walks you through the set-up and controls the system on a day-to-day basis, including intuitive sound settings, so you can tune LS50 Wireless II to your own personal tastes.

Attention To Every Detail

The LS50 Wireless II will also fits comfortably into your living space when it comes to style. The lowdiffraction, curved baffle is precision modelled around the Uni-Q driver array, while eye-catching heat sinks and colour-matched ports are located on the well-equipped rear. LS50 Wireless II is available in three matt finishes, Carbon Black, Titanium Grey, Mineral White as well as a Crimson Red Special Edition. All the colours are mirrored on both the drive units and the rear-facing port means the LS50 Wireless II looks fantastic from any angle. On the LS50 Wireless II’s underside, each corner has a threaded inset allowing the speaker to lock onto the top of the new KEF S2 Floor Stands, which also boast integrated cable management and a mass loadable column. The stands are all colour matched to your finish of choice. For even more impact and bass extension, LS50 Wireless II features two subwoofer outputs, one on each speaker. When paired with KEF’s KUBE range or KF92 subwoofers, music and film becomes even more impactful.

Most Accurate, Immersive Sound

When it comes to physical technology, LS50 Wireless II takes its lead from KEF’s LS50 Meta passive loudspeakers. A truly revolutionary tool in the KEF acoustic armoury, Metamaterial Absorption Technology (MAT) is a highly complex maze-like structure, where each of the intricate channels efficiently absorbs a specific frequency. When combined, the channels act as an acoustic black hole, absorbing 99 of the unwanted sound that comes from the rear of the tweeter, eliminating the resulting distortion and providing a purer, more natural sound.
