It is five years since the launch of the original KEF LS50 commemorating KEF’s 50th anniversary. Following the original launch, KEF have introduced additional finishes to the range and this time it’s a very special limited numbered edition variant, the KEF LS50 Black Edition loudspeaker.
Featuring a dark black Uni-Q driver array set against a subtly patterned black trim ring encased in a matt black cabinet finished with metallic powder, each pair of this numbered Black Edition celebrates the same award-winning acoustics with added sophistication.
The KEF LS50 mini monitor loudspeaker is an innovative concept derived from the legendary LS3/5a, designed to bring the professional studio monitor concept into the home.
Rarely the case in such a compact design, the KEF LS50 Loudspeaker 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.
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.
The KEF LS50 Loudspeaker 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.
