KEF LS50 Wireless Speakers


Product Description

Inspired by the legendary LS3/5A, LS50 passive speakers were introduced to the world at KEF's 50th anniversary. Expertly delivering a rich, multi-dimensional 'soundstage experience', people loved LS50, creating huge buzz at launch and bringing the professional studio monitor concept into the home. LS50 passive speakers were designed with the belief that everyone deserves to experience quality sound. After five years, KEF stepped up to the challenge of creating a music system for the digital age. It took LS50 passive speakers to the next level, turning them into a complete, fully active digital studio monitor system for the home.

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. It brings Hi-Fi sound to a new generation of listeners with digital music lifestyles. 

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.

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.
