KEF LS50 Wireless – a complete and fully active system

KEF LS50 Wireless

Singapore, @mcgallen #microwireinfo, 22 March 2017 – KEF proudly presents LS50 Wireless, a complete and fully active music system, which just happens to look like a pair of LS50. Sharing the same winning acoustic features of LS50, LS50 Wireless enables the user to easily enjoy excellent music reproduction, hitherto only achieved by putting together a system based on high quality separate components.

Six years ago, with the belief that everyone deserves to experience quality sound, the LS50 passive speakers were introduced at KEF’s 50th anniversary. Now, with the LS50 Wireless Bluetooth system, KEF has developed a complete, fully active, system that retains all the acoustic features and benefits of LS50 with everything built in to allow a multitude of connectivity needs.

Astounding multi-dimensional sound

LS50 Wireless delivers smooth and detailed sound that creates an intense, rich and multi-dimensional soundstage experience, made possible by expert acoustic design and state-of-the-art technologies. Despite its small enclosure, the wireless pair will deliver a sweet spot listening experience regardless where you sit in a room. This is due to KEF’s patented Uni-Q® technology that allows the speaker to create three-dimensional sound image, for your ultimate listening pleasure.

The FEA*-designed cabinet, Uni-Q® driver, constrained layer damping bracing, precision-made curved baffle and the elliptical flexible sound port, all part of the LS50 pedigree, are retained. These features prevent cabinet vibrations, enhance radiating sound, and reduce resonances and colouration. New additions include an end-to-end 192kHz/24-bit high-resolution digital signal path, a dedicated DAC per channel, a streaming pre-amplifier and factory-optimised amplification in a bi-amp dual mono configuration (200 + 30 watts per speaker). Combined with a time-correcting DSP crossover, the incredible award-winning sound of Uni-Q® is taken to the next level.

Simplicity meets sophistication

The beauty of the LS50 Wireless is its effortless combination of simplicity and elegance. It is brilliantly easy to set up and use, yet offers sophisticated audio profile for audiophiles with expert audio engineering. The audiophile grade system configuration includes an end-to-end high-resolution digital signal path, dedicated DAC per channel, streaming pre-amplifier, and 2 units of 230-watt amplification in a bi-amp mono configuration.

To make the LS50 Wireless a total music system, a comprehensive range of connection options are available, including 2.4GHz/5GHz Dual-band Wi-Fi, Bluetooth 4.0 with aptX codec, Asynchronous USB Type B input, TOSLINK Optical and RCA Phono, allowing connection to a wide range of sources.

Dedicated LS50 Wireless mobile application

A dedicated app for LS50 Wireless, available on both IOS and Android, enhances the user experience during network setup, music streaming, playback, and control. The app also includes 3 user levels of customisable EQ settings for personal music preference.

LS50 Wireless contains sophisticated components. Replicating this system using a traditional Hi-Fi setup typically would cost at least double.

Audiophile grade amplification is partnered with audiophile grade sound processing. The advanced time correcting DSP crossover solves this problem and ensures perfect time alignment between low and high frequencies so that every note arrives to the listener at the same time. This theoretical ideal is now made practical in regular rooms by the unique sound dispersion properties of Uni-Q®, which no other active speaker design can correct.

About Uni-Q®
Of the many landmark innovations KEF has pioneered, arguable the greatest of all is the Uni-Q® point source driver array, with its outstanding acoustic clarity and off-axis dispersion. With over twenty years of continuous innovation and development, the Uni-Q® driver arrays achieves a level of sound quality over a broad area simple not achiever from conventional speakers. With Uni-Q®, sounds come at you so naturally that it seems as if the musicians or actors are actually there in front of you. Whether you are in the centre of the room or off to one side, recordings sound uncannily real and utterly convincing. Uni-Q® achieves this because, unlike conventional speakers, the sound that is critical to the experience comes from the same point in space, and is produced in a controlled and continuous way over the whole audio range.
