KEF LS50W High Resolution Music System - Grey




LS50 Wireless

LS50 Wireless is a complete and fully active system designed for the way high resolution music is now enjoyed. Based on the award-winning LS50 speakers and sharing the same acoustic features, the LS50 Wireless enables users to easily enjoy exceptional sound quality previously only achieved by an array of sophisticated components.

The LS50 pedigree

All the acoustics features and benefits of the award-winning LS50 speakers are retained. These include the FEA-designed cabinet, Uni-Q driver, constrained layer damping bracing, precision-made curved baffle and the elliptical flexible sound port. Together these prevent cabinet vibrations, radiating sound, resonances, and colouration.

A complete, fully active system

With end-to-end 192kHz/24-bit high-resolution digital signal path, a dedicated DAC per channel, a streaming pre-amplifier, and factory-optimized 230-watt x2 amplification in a bi-amp dual mono configuration makes the LS50 Wireless a total music system.

LS50 Wireless includes a broad range of connectivity options, including 2.4GHz/5GHz Dual-band Wi-Fi, Bluetooth 4.0 with the aptX codec, Asynchronous USB Type B, TOSLINK Optical, and RCA Analog. A dedicated app for LS50 Wireless, available on iOS and Android, simplifies network setup, music streaming, playback and control.

Uni-Q sound taken to the next level

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.
