KEF Blade

KEF Blade offers the highest quality sound reproduction available through KEF’s Single Apparent Source technology. Single Apparent Source technology ensures the entire frequency range radiates from one point in space, creating a sound picture that is virtually indistinguishable from a live performance. KEF Blade is further enhanced by a glass-reinforced composite cabinet that matches the speaker’s high performance sound quality with elegant industrial design. KEF’s Single Apparent Source ensures that individual driver sections - for bass (LF), midrange (MF) and treble (HF) - of a multi-way loudspeaker work together and produce sound-fields that appear to come from the same point and place, which is especially important at the crossover frequencies where the sound output switches between drivers. The Single Apparent Source is a perfect extension of the new, fully pistonic KEF Uni-Q™ MF/HF array, and includes the bass drivers for the first time. Together they combine to form a seamless point source driver array that can handle the entire frequency range. Four 9” (22.5 cm), newly developed bass drivers deliver the KEF Blade’s distortion-free low frequency response. The engineering principle behind their configuration is simple - let the huge forces of each moving cone cancel each other out by arranging them in opposed, symmetrical pairs - but its effective implementation is fraught with engineering obstacles. The force produced by the bass drivers is so strong that the massive rear magnets have had to be bonded directly to each other to obtain the full benefit of this technology. They are side firing so their acoustic center coincides with those of the all-new, latest generation Uni-Q midrange driver and tweeter - forming the ground breaking Single Apparent Source technology.

Features

KEF Blade is the world's first Single Apparent Source loudspeaker. Conceived from the outset to extend the boundaries of high end audio, it's a unique synthesis of innovative engineering and groundbreaking design based on a new architecture that achieves the ideal point source to which all speakers aspire. This is because the four sophisticated new bass drivers are configured so that their combined acoustic center occupies exactly the same point in space as that of the Uni-Q HF/MF array, so the sound appears to emanate from a single, flawlessly coherent source.

Benefits

KEF Blade is a revolutionary loudspeaker combining unmatched precise sound imaging and elegant design. KEF Blade is the evolution of KEF's widely acclaimed Concept Blade. It offers the highest quality sound reproduction available through KEF's Single Apparent Source technology. Single Apparent Source technology ensures the entire frequency range radiates from one point in space, creating a sound picture that is virtually indistinguishable from a live performance. KEF Blade is further enhanced by a glass-reinforced composite cabinet that matches the speaker's high performance sound quality with elegant industrial design.
