With conventional planar magnetic models, amplitude is an increasing low range, and since the diaphragm comes into contact with magnets, it was necessary to raise the frequency of bass tones to a level that the driver unit can reproduce.
Reproducing subtle high frequencies, the lightweight nature of the diaphragm comes before anything else. Compared to other dynamic models with the same diameter, D8000's diaphragm is 1/3 lighter. A super thin aluminum coil has been etched on the extremely lightweight film diaphragm, the adhesive essential for use between the coil and the diaphragm of dynamic models.
With a combination of the planar magnetic model's subtle high frequecies and the dynamic model's volume and open bass tones, you discover new things about music you're used to listening to when you use D8000.
