KEF mark 50 years in the hifi business with the LS50s- bookshelf speakers with excellent performance and clever design features. Fitted with KEF's point source "Uni-Q" drivers- so they deliver a full and open sound- and unique tweaks to the cabinet to improve the performance.. Whether for stereo music or home cinema surround sound applications, the LS50s are a great choice.

For what is rarely the case in such a compact design, the LS50 monitors deliver a rich, multi dimensional soundstage experience, filling the room with beautiful sound that is out of all proportion to their size. This model includes (at time of writing) patent pending acoustic designs, together with state-of-the-art technologies from the flagship KEF Blade speakers.

In thanks to their advanced design, with respect to their heritage, the LS50 provide the ultimate studio experience - even in the smallest of spaces.
