KEF
'Of all art, music is the most indefinable and the most expressive, the most insubstantial and the most immediate, the most transitory and the most imperishable. Transformed to a dance of electrons along a wire, its ghost lives on. When KEF returns music to its rightful habituation, your ears and mind, they aim to do so in the most natural way they can ... without drama, without exaggeration, without artifice'. Raymond Cooke, KEF founder

LS50 Wireless delivers a clear, accurate and transparent sound that creates an intense, rich, and multi-dimensional soundstage experience. Made possible from its small enclosures through expert acoustic design and state-of-the-art technologies.

LS50 Pedigree

Cabinet vibration, sound radiation, resonance, and colouration are all eliminated through the seamless integration of the award-winning LS50 speaker's acoustic features. These include the FEA-designed cabinet, Uni-Q driver, constrained layer damping bracing, precision-engineered curved baffle and elliptical flexible sound port.

Every Spot is Sweet - Uni-Q

Get a three-dimensional sound image wherever you sit, for a sweet spot listening experience anywhere in a room using KEF's patented Uni-Q technology. Now in its 11th generation, it places the tweeter in the acoustic centre of the bass/midrange cone, allowing LS50 Wireless to create a more detailed, accurate and beautifully integrated three-dimensional sound image.

Crossover Timing Correction

High and low frequencies should hit your ears at exactly the right time. This perfect time alignment was only an ideal case in theory previously, and perfectly accurate sound could only be experienced within a small 'sweet spot'. With LS50 Wireless’ advanced time correcting DSP crossover and the unique sound dispersion abilities of Uni-Q, time corrected accurate sound can be achieved in different types of rooms. This is a feat that cannot be reproduced by any other active speaker.

Audiophile Grade System Configuration

Audiophile-grade sound means audiophile-grade technologies. LS50 Wireless delivers this with an array of sophisticated components built in. Through expert audio engineering, LS50 Wireless includes an end-to-end 192kHz/24-bit high-resolution digital signal path, dedicated DAC per channel, streaming pre-amplifier, and a 230-watt x2 amplification in a bi-amp dual mono configuration. All factory-optimised.

Flexible User Control

Use the touch sensitive control panel or the remote control to ensure complete control of LS50 Wireless from a different aspect. A dedicated iOS or Android app can allow detailed adjustment to optimise sound for different rooms. 

 

 

Review – Gramophone Magazine

"LS50 Wireless is indubitably a very tempting introduction to an ‘alternative universe’ of home audio, one which I am sure will find favour with many users, as much for its captivating sound quality as its remarkable flexibility and simplicity." (Download full review)
