    The KEF LS50s are 2-way bookshelf speakers with incredible performance

    Fitted with KEF's point source Uni-Q drivers, with a 130mm bass/mid-range driver and a 25mm aluminium dome tweeter with 'tangerine' waveguide, the LS50s fill your room with exciting and engaging sound

    Cutting edge technology is used in the cabinet construction as well. With a curved front face and bass port designed with the help of Finite Element Analysis and Computational Fluid Dynamics every element of the LS50 works to provide the finest possible sound

    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.


    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.



    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
