Product Features
| LS50 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. |

Press and Awards
| Stereophile Recommended Component - A(Restricted Extreme LF) - 2017 |
| "The LS50 produced a surprisingly large, clean, transparent sound, with natural tone color and precise, stable stereo imaging, said JA, who also noted superb measured performance. "Recommended. Highly." ST found the LS50's tonality "spot-on, more neutral than sweet," adding that the diminutive KEFs could deliver "surprising bass: down to around 50Hz." ST's verdict: "I haven't had such great sound in my listening room since the departure of Quad's ESL-2805 electrostatics." As SM put it: "In 13 years of working at Stereophile, I have not seen another component that offers such a radical combination of value and performance."

| Review : LS50 - The Absolute Sound 07/2013 |
| "The KEF LS50 is one of the most all-around-satisfying little speakers I’ve reviewed in some time. Construction and execution are exemplary. It delivers the kind of performance that deserves to be on a Wheaties box. And there’s an incalculable coolness factor that makes it a breath of fresh air. The LS50 also answers the classic question, 'Who says you can’t teach an old box new tricks?'" |

| Reviewers Choice award |
| “The LS50 is nothing short of a masterpiece of a minimonitor, priced so that anyone serious about audio can buy a pair -- and probably should, if only to know how great a small speaker can be. Time hasn’t been as much on my side as it’s been on KEF’s -- the LS50 is one of their best speakers yet, and one of their best values; it’s proof that, as it ages, this company seems to get better and better.” |
