KEF LS50 Wireless Speakers (Display Model)

The KEF LS50 Wireless Speakers, with their expert acoustic design and small enclosures, deliver a clear, accurate and transparent sound. It will guarantee a rich, multi-dimensional soundstage experience that is just as much intense as it is enjoyable. 

This acoustic design works to eliminate any cabinet vibration, sound radiation, resonance and colouration. The FEA-designed cabinet, Uni-Q driver, constrained layer damping bracing, the precision-engineered curved baffle and elliptical flexible sound port, delivering a pristine listening experience as a result.

KEF's patented Uni-Q technology creates a three-dimensional sound image, no matter in which position you are sitting, creating a sweet spot listening experience anywhere in the room. The tweeter in the acoustic centre of the bass/midrange cone, the KEF LS50 Wireless will deliver a more detailed and accurate integrated three-dimensional sound image. 

The high and low frequencies of the KEF LS50s will hit your ears at exactly the right time, creating time corrected, accurate sound in all types of different rooms. This is possible with the advanced time correcting DSP crossover included and Uni-Q's unique sound dispersion abilities; a feature which cannot currently be reproduced by any other active speaker.

Audiophile-grade technologies used in the KEF LS50 Wireless Speakers include an end-to-end 192kHz/24-bit high-res digital signal path, a dedicated DAC per channel, streaming pre-amplifier and a 230-watt x2 amplification. In a bi-amp dual mono configuration, all of which are factory-optimised to ensure the best, audiophile-grade sound possible. The end-to-end 192kHz/24-bit high-resolution digital signal path ensures that every piece of information from a high-resolution music source is reproduced fully and accurately, creating a signal path from the input to the amplifiers. 

The standard RJ45 termination for the interconnect cable between speakers and a Cat 6 shielded cable is included so that bandwidth and performance headroom is greatly improved, rejecting noise and electromagnetic compatibility, promising consistent high-quality performance. 

The KEF LS50 Wireless Speakers include a selectable EQ that offers to tune for the compensation of different mounting scenarios, listening environments and allowing for more options when it comes to the placement and positioning of the speakers.

The quality of the KEF LS50 Wireless Speakers is not impeded by any stressful installation, with a setup that has been made as easy as possible thanks to Kef's Plug and Play method. Simply connecting both speakers to a power source and plugging in an audio source will allow you to enjoy your music through high-quality sound in no time. 

Connectivity options Connecting to your sources have been made just as easy, with a wide range of connectivity options available to you, such as the 2.4GHz/5GHz Dual-Band Wi-Fi connection, Bluetooth apt-X 4.0, Asynchronous USB Type B, TOSLINK Optical and RCA Analogue. These options allow you to connect up to 12 devices, with a maximum 8 Bluetooth devices open to you, allowing you to switch between inputs conveniently. 

All of these connectivity options allow for connection to a plethora of sources, opening up the KEF LS50 Wireless Speakers' amazing sound to your computer, TV, turntables, games consoles and even your mobile devices and tablets.

The included remote control or the touch-sensitive control panel located on the top of the KEF LS50 Wireless Speakers allows for simple user control. However, control becomes even more flexible with the addition of the dedicated iOS and Android app. 

Downloading the app will allow you to pair your mobile devices through the Bluetooth connection, opening up easy, intuitive options and enabling full control of your system, including optimisation of sound and specification of distances, all from the comfort of your armchair.
