WVL SERENDIPITY – Magnet Construction

The drive. The only magnetic "12-cylinder" we know.  Developed according to the latest findings in modern loudspeaker manufacturing. Using nanometer-precise white light interferometers for absolute measurement of displacement, distance and timing, the modulation of the force factor is reduced to the absolute minimum. After ideal shaping of the ferromagnetic components of the magnet system for the overhanging voice coil, electrically damping rings and another magnet are also used at the appropriate location. Both contribute to the linearity of the overall system. The result is the lowest magnetic hysteresis distortion of permanent magnet systems on the market. Nothing off the shelf. 

To ensure that the electromechanical counterpart also matches the qualities of the magnet system, the voice coil is wound in an interleaved manner on a damping-free carrier and positioned so that only the slightest non-linear distortion occurs during dynamic excitation. In fact, with conventional magnet systems and voice coils, measurements show that the force acting on the entire moving group of a loudspeaker varies greatly with different excursions. Ultimately, in conventional loudspeakers, the diaphragm is then driven by forces of varying strength. This leads to imprecision in music reproduction that must be overcome. 

The nested winding technology and the drive tuned to it result here in clearly audible lower frequency and phase modulation distortions.
