Check out the KEF Concept Blade speakers that were specially developed to demonstrate the British hi-fi specialist’s technical know-how. Taking three years to complete, these life-size boomboxes would be able to garner a place in any modern art gallery thanks to their rare marriage of performance and aesthetics in a single package. The whole speaker case is made from woven carbon fiber, and are able to handle the full audio spectrum right out of the box. This was achieved by using four side-firing woofers to boost bass extensively, while holding their proprietary Uni-Q driver within for more natural-sounding vocals.
