KEF Blade I Single Apparent Source Loudspeaker. Three-way bass reflex. Single source driver configuration. Uni-Q array: 5" MF, 1" HF, 9" LF x 4. Colour Piano Black. SOLD AS PAIR *** BROUGHT IN TO ORDER ONLY*** BLADE shares a new architecture that achieves the ideal point source, with the four sophisticated bass drivers (225mm/9") configured so that their combined acoustic centre 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. BLADE-PB Sculptural and acoustically inert, the slender parabolic enclosures are engineered never to interfere with the purity of the output. Inside, you find ingenious new venting, bracing and wave management technologies. Every component operates so comfortably within its performance envelope that you experience noticeably more precise imaging than is possible with conventional speakers. Just as KEF's philosophy has always been to innovate in pursuit of the most accurate and realistic sound, BLADE speakers are about perfecting a groundbreaking concept to delight people who really love music. Whatever your taste, BLADE is what all great design aspires to: being the best they can possibly be.
