With conventional planar magnetic models, amplitude was an increasing low range, and the diaphragm came into contact with magnets. To solve this problem, we took measurements by conducting diaphragm simulations using the finite element method and laser Doppler devices numerous times, and estabished new diaphragm braking technology known as AFDS - Air Film Damping System.
Newly-developed open type earpads
With D8000, the reproduction band of bass frequencies has been extended through AFDS, and it has become possible to sufficiently reproduce bass frequencies even with earpads that are not sealed tightly just with driver unit ability. The earpads that great influence sound quality have been newly developed specially for D8000 from highly-breatheable foam and specialized fibers.
