“Manger’s ingenious drive unit replicates the basilar membrane in the human ear and produces acoustic signals that are temporally and tonally correct at the same time. Avoiding the piston-shaped movement of a conventional driver, Manger created a bending-wave transducer with a flat, circular membrane of angular flexible foil, excited by a voice coil to make back and forth movements. Yet, and here’s the clever part, its waves radiate concentrically from the centre to the edge; the voice coil only having to excite the membrane’s centre for the sounds to be radiated by the bending waves around the coil.”
