To the casual observer, the LS50 might seem like a minimalist speaker with just one driver, but in reality it is a very sophisticated product. The speaker is in fact one of KEF's famous Uni-Q units with the tweeter placed in the acoustic center of the midwoofer. The latest version, colored rose gold, uses a cone membrane made from a special magnesium-aluminum alloy and is capable of increased floating head excursion to improve low-frequency reproduction. The cabinet is not only elegantly finished but also excels in sturdiness with layers of damping material between the walls, internal bracing and front panel. As promised, the LS50 delivers authoritative sound with excellent soundstage reconstruction capabilities and a low-frequency consistency rarely associated with such small dimensions: close your eyes and you'll feel like you're listening to a much larger speaker.

About the brand

KEF is a British brand of high-end loudspeakers, founded in 1961 by Raymond Cooke in Tovil, near Maidstone, Kent, England. The name itself—an acronym for Kent Engineering & Foundry—recalls the company's origins, founded next to a metal foundry. KEF positions itself in the premium segment of the hi-fi market, targeting discerning audiophiles seeking faithful, natural, and technologically advanced sound reproduction.

KEF's corporate philosophy is rooted in the education of its founder. Raymond Cooke, an engineer with a background in design at the BBC and then at Wharfedale, brought a rigorously scientific approach to the world of loudspeakers: KEF was among the first manufacturers to use new synthetic materials for speaker diaphragms, with a single goal: to bring listening as close as possible to a live musical event.

The innovation that made KEF famous worldwide is the Uni-Q driver, introduced in 1988. In this system, the tweeter is placed precisely at the acoustic center of the mid-woofer, creating a single point source: the result is extraordinarily coherent sound, a wide and stable soundstage, and optimal listening even off the central axis, from any position in the room. Constantly refined over the years, Uni-Q technology has become the brand's unmistakable signature.

KEF research has never stopped. With Metamaterial Absorption Technology (MAT), introduced in 2020, the company has developed a special acoustic labyrinth capable of absorbing noise.missionthe rear of the tweeter, reducing distortion and delivering exceptionally pure sound. It's the heart of the celebrated LS50 Meta, an evolution of the LS50 launched in 2012 for the brand's fiftieth anniversary; MAT technology received the 2020 Innovation of the Year award from What Hi-Fi?

The KEF catalog ranges from compact bookshelf monitors to large reference floorstanding systems: from the historic LS3/5A—a mini-monitor designed by the BBC with KEF speakers—to the highly acclaimed Q and R series, all the way to the flagship Reference and Blade, true acoustic sculptures. The result of a constant dialogue between engineering and design, KEF speakers combine top-level performance with a refined and instantly recognizable aesthetic.

Choosing KEF means bringing home over sixty years of British innovation and the promise of faithful, detailed, and emotionally resonant sound. Discover the KEF range available from Audiocostruzioni and let yourself be won over by the coherence and naturalness of the Uni-Q sound.
