The KEF Concept Blade is a set of enormous one-off speakers engineered to demonstrate the British hi-fi specialist's technical know-how. Developed over a three-year span, these man-size boomboxes are a work of art in both aesthetics and performance.
Clad top to bottom in woven carbon fibre, these gorgeous concept speakers are capable of supporting the full audio spectrum out of the box. To achieve this feat, they employ four side-firing woofers to boost bass extensively and the company's UniQ driver for more natural-sounding vocals. You can't buy these -- they're just for show -- but you can read more in the company's brochure here (PDF).
