Hello Music Enthusiasts, We are running an additional $100 off for our Valentine’s Day special while units last! Enjoy 😉
You're looking at a beautiful pair of KEF LS50 Wireless speakers. I have 3 different finishes available and very limited quantities. These are brand new and unopened. Please reach out with requested finish, if your color scheme is sold out... you will be informed immediately.
The LS50 Wireless Music System is a complete and fully active music system. Sharing the same winning acoustic features of KEF’s renowned LS50, LS50 Wireless enables the user to easily enjoy excellent music reproduction, previously only achieved with a system comprised of separate high quality components. Created without compromising on any of LS50's award winning acoustic capabilities, LS50 Wireless adds audiophile-grade amplification and sound processing, as well as extensive connectivity. The LS50 Wireless features Tidal Streaming, is a Roon endpoint providing the ultimate in flexibility and connectivity, and is compatible with all music streaming services.
All of the acoustic features and innovations that set the LS50 apart from every other speaker in its class remain. The FEA-designed cabinet with its constrained layer damping bracing and precision engineered curved baffle, the Uni-Q driver and the elliptical flexible port all work in concert to prevent cabinet vibration and resonances that produce unwanted sound coloration – putting you that much closer to how your favorite music was intended to sound.
Uni-Q sound taken to the next level
To get the most out of your music, every note should arrive at your ears at exactly the right time. Before KEF perfected our Uni-Q technology, this perfect time alignment could only be experienced in a small 'sweet spot,' leaving listeners outside of the ‘sweet spot’ with a less than ideal listening experience. Uni-Q changed that, opening up the optimum listening space to practically every spot in your room. The LS50 Wireless employs an advanced time correcting DSP crossover which takes that awesome achievement to the next level by correcting for inherent time delays introduced in the crossover stage. Amazing sound dispersion matched only by a live music performance is now attainable in virtually every room. This incredible achievement cannot be reproduced by any other active speaker.
Crossover Timing Correction
Every note should hit your ears at exactly the right time. Previously, this perfect time alignment was only a theoretical ideal 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, accurate sound reproduction can be achieved in practically every location in any type of room. This is a feat that cannot be reproduced by any other active speaker.
A complete fully active system
The LS50 Wireless features an end-to-end 192kHz/24-bit high-resolution digital signal path, a streaming pre-amplifier, and two separate DACs for each channel, for a total of four. Powered in the analogue stage by an incredibly fast and clean 230 Watts per channel in a bi-amp dual mono configuration, the LS50 Wireless is a complete, high-fidelity music system that will cost you far less than you’d spend putting together the separate components necessary to match the performance of the LS50 Wireless. LS50 Wireless gives you all of the connectivity options you’ll need to get the most out of your music, including 2.4GHz/5GHz Dual-band Wi-Fi, Bluetooth 4.0 aptX, Asynchronous USB Type B, TOSLINK Optical, and RCA-type line-level analogue inputs. A dedicated LS50 Wireless app (available for iOS and Android) easily facilitates network setup, music streaming, playback and DSP control.
An incredible listening experience is easy as plugging in. Simply connect both LS50 Wireless speakers to a power source and connect an audio source to enjoy high quality sound that music deserves. Adjust how the LS50 Wireless sounds using a selectable EQ tuned to compensate for different mounting scenarios, creating more options for placement and positioning. Regardless of placement, Uni-Q technology disperses sound evenly for total listening enjoyment. 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.
