DUAL CONCENTRIC

摘要

First developed by Tannoy's chief engineer Ronnie H Rackham and patented in 1947, the 15in Monitor Black was the world's first full bandwidth coaxial transducer trademarked 'Dual Concentric'. Proclaimed the most accurate loudspeaker available, it was used initially as a calibration instrument for microphones. It soon found favour with countless recording and broadcast studios. Passing decades have seen Tannoy develop and refine the DC concept, implementing new materials and manufacturing processes. Enhancements include the Tulip and Pepperpot waveguides for the tweeters, Tannoy aficionados constantly arguing about which they prefer. Tannoy has gone from strength to strength since becoming part of the TC Croup, a holding company that includes several manufacturers such as TC Electronic of Denmark, Canadian fab-less semiconductor company TC Applied Technologies, and Swedish Lab.gruppen that acquired Lake Technology from Dolby in 2009.
