Simplicity meets Sophistication

The beauty of the KEF LS50 Wireless is its effortless combination of simplicity and elegance. It is easy to set up and use, yet offers sophisticated sound fit for audiophiles through inspired audio engineering and the Uni-Q driver.

End-to-End High-Resolution

Every piece of information from a high-resolution music source is reproduced fully and accurately through an end-to-end 192kHz/24-bit high-resolution digital signal path. This creates a signal path from the input to the amplifiers that is completely digital and high resolution.
A standard RJ45 termination for the interconnect cable between speakers and a Cat 6 shielded cable improves bandwidth and performance headroom while rejecting noise and electromagnetic compatibility, ensuring LS50 Wireless sound is consistently high-quality.

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, KEF 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.

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 KEF 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.

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 KEF LS50 Wireless to create a more detailed, accurate and beautifully integrated three-dimensional sound image.
