Description

The KEF Q11 floorstanding speakers represent the flagship of the Q Series, offering a 4-way configuration in a sleek, refined cabinet. These floorstanding hi-fi speakers integrate KEF's renowned Uni-Q technology , which positions the tweeter in the center of the midrange driver for uniform sound dispersion and improved temporal coherence. The innovative design includes an oval woofer with a polymer diffuser dedicated to the lowest frequencies and a traditional driver for the mid-bass, ensuring precise control of the entire sound spectrum.

The adjustable bass reflex configuration on the rear panel allows you to tailor the frequency response to your listening environment, while dual binding posts allow for bi-wiring to optimize performance. With a sensitivity of 91 dB and power handling of up to 200 W, these speakers are ideal for both medium-powered tube amplifiers and more powerful systems. Their excellent stereo imaging and ability to create a deep soundstage make them perfect for listening to classical, jazz, and rock music, where precise instrument localization is crucial.

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, which began within the premises of a metallurgical 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 from the BBC laboratories, brought a rigorously scientific approach to the world of loudspeakers: KEF was among the first manufacturers to experiment with new synthetic materials and advanced measurement and design tools, with a single goal: to bring listening as close as possible to the 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), the company has developed a special acoustic labyrinth capable of absorbing almost all the sounds.missionthe rear of the tweeter, reducing distortion and delivering exceptionally pure sound. It is the heart of the celebrated LS50 Meta, an evolution of the legendary LS50: one of the most awarded and beloved bookshelf speakers of all time.

The KEF catalog ranges from compact bookshelf monitors to large reference floorstanding systems: from the historic LS3/5A—a mini-monitor associated with BBC studios—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.
