Astounding Multi-Dimensional Sound

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.

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.

Simplicity meets Sophistication

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

Plug and Play

The 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.

Interior Design Friendly

With only two speaker enclosures, LS50 Wireless blends easily into the home without the clutter. Available in three sharp colours, Titanium Grey/Red; Gloss Black/Blue; Gloss White/Copper, the right colour combination to match the home is easy to find.

Placement Flexibility

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.

Comprehensive Connectivity

Connect a huge range of devices with LS50 Wireless' 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. Connect up to 12 devices in total, including a maximum of eight Bluetooth devices and switch between audio inputs conveniently.

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.
