Interview - Planar Magnetic Speaker Technology
Author: Jon Herron, Wisdom Audio

Our planar magnetic drivers use an advanced thin film membrane to move the air. This film is actually lighter than the air that it is responsible for moving, so it can respond instantly to the smallest detail in the signal. It has vastly less inertia than traditional cone & dome drivers, so the signal is never blurred or inhibited in any way.

The motive force is provided by a voice coil that is printed on the film (in a manner similar to how circuit boards are manufactured), which is suspended in a strong magnetic field provided by rare earth neodymium magnets behind and in front of the film. The ratio of available force to the moving mass is huge, which means that the diaphragm does exactly what it is told; nothing more, nothing less. The dynamics and detail are remarkable.
