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.
An innovative concept inspired by the legendary LS3/5a, the LS50 mini monitor speaker is designed to bring a professional studio monitor concept into the home.
Rarely the case in such a compact design, the LS50 monitor delivers a rich, multi-dimensional 'soundstage experience’ that is out of all proportion to its size. Patent-pending acoustic designs, together with state-of-the-art technologies from KEF’s latest flagship Blade loudspeaker, provide the ultimate studio experience – even in the smallest of spaces.
Breakthroughs
Creating a small housing capable of delivering such a spacious sound is the result of considerable research and development. In cabinet construction, baffle shaping and port design, LS50 breaks new ground with patent-pending technology. All this is made possible by KEF's leadership in modern research (including techniques such as Finite Element Analysis and Computational Fluid Dynamics*). LS50's unique technology offers by far the cleanest, most accurate studio-grade performance of any mini monitor.
Uni-Q®
LS50 employs revolutionary technology developed for Blade, KEF's latest flagship loudspeaker. Using the very latest Uni-Q driver, specifically designed for this model, LS50 radiates an extremely large listening sweet spot and delivers a remarkably fast, clean sound. And, because LS50 neither adds nor subtracts a single sound, it's effortlessly natural and accurate too.
