Manger

Almost 30 years were spent in systematically searching, testing, researching and rejecting until the vision of the natural resonance-free radiation principle became an acoustic reality. This has resulted not only in one of the most elegant appearances in the loudspeaker market, but also in a masterpiece of precision mechanics. The decisive factor in the Manger sound transducer was the logical turning away from the more than 75 year-old transducer principle used in conventional loudspeakers, therefore doing without the piston-like movements with their faulty reciprocal overshooting. A well-known typical 3-way speaker. Clearly to be seen the time-displaced displacements and transient errors of tweeter, mid-range and woofer. This speaker has been designed exclusively for a smooth frequency response. Instead, Josef W. Manger relied on the principle of bending waves, which starting from the centre of a plate-like diaphragm, travel to the outside, like waves after a stone is thrown into the water. The rigidity of this thin flexible panel increases from the centre to the outside at an equal ratio, very similarly to the basilar membrane in our ear. High frequencies quickly run out in the inner area of the membrane, whereas long waves (low frequencies) concentrically reach right to the edge at the star-shaped damper. There they are absorbed so that no reflections can come from the edge.
