The Final D8000 is a highly-acclaimed advanced planar magnetic headphone it’s beautifully built and sounds absolutely sublime!
With AFDS (Air Film Damping System), the planar magnetic model was reinvented.
Leaving the merits of the planar magnetic model – a lightweight vibration system
and superior reproduction of high frequencies – as is, the employment of AFDS expands the reproduction frequency band with a bass bias, and makes the use of
breatheable earpads possible. Compared to the conventional planar magnetic model,
with which tightly sealed earpads had to be used to suplement bass frequencies, the natural, open sound achieved is of a quality worthy of being termed a reinvention.
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. To make up for the lack of bass tones, the inside of the earpads have been tightly sealed, and the front section of the diaphragm has been made a closed space.
This is the same principle as earphones with sealed earpieces being able to reproduce bass frequncies 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.
The Final D8000 model is manufactured in Kawasaki. Together with the precision of individual parts, the precision involved in the assembly process depends on the precision of the tools known as jigs that assist in the assembly process.So as to be able to fine-tune even the slightest of irregularities in jig precision during the assembly process, we design and manufacture production jigs and measurement jigs ourselves.
We developed manufacturing apparatus such as a diaphragm formation machine and a diaphragm tension meter in-house, specifically for the Final D8000.
To create truly good products, it is necessary to get to the core of the manufacturing process of parts close to the raw material. What is good about “made in Japan” is that when doing so, you can gain the cooperation of those manufacturers close to the material. By contolling everything together, from sourcing the raw materials through to the assembly of the product, we have achieved high-quality products.
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.
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.
