This is the same principle as earphones with sealed earpieces being able to reproduce bass frequencies despite their small size. By sealing the inner earpads, it is possible to produce bass tones across low frequency bands; these become the bass tones produced within a sealed space the same as earphones.
With D8000, the problem with the diaphragm coming into contact with magnets has been solved through AFDS (Air Film Damping System), and it has become possible to reduce the frequency of the bass tones that the driver unit can reproduce. Combined with breatheable earpads, bass tone reproduction with a volume and open sound only achievable with superior dynamic models is possible.
<b>“Subtle high frequencies”</b>
In 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, and as such, the adhesive essential for use between the coil and the diaphragm of dynamic models - which has a very negative effect on sound quality - is not necessary. This is an important part, packed with know-how. With D8000, this problem is solved theoretically, and reproduction of subtle high frequencies has been achieved.
<b>“The combination of the planar magnetic model's subtle high frequencies
and the dynamic model's volume and open bass tones”</b>
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; they have you wanting to listen to your favorite music over and over again. With this product, you realize
that high sound quality provides the impetus for experiencing the deeper aspects of music.
