Final have reinvented the planar magnetic model driver with AFDS (Air Film Damping System)
With the development of the new AFDS (Air Film Damping System), they have achieved sound quality that has both the sensitive high ranges of planar magnetic models and the volume and open feel bass tones of dynamic models.
This is a product that will have you making new discoveries from music you’re used to listening to, and will have you wanting to listen to your favorite music over and over, reaffirming the pleasure that audio products bring.
A combination of the sensitive high ranges of planar magnetic models and the volume and open feel bass tones of dynamic models.
“Volume and open feel bass tones”
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 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.
“Subtle high frequencies”
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 aluminium 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.
“The combination of the planar magnetic model’s subtle high frequencies and the dynamic model’s volume and open bass tones”
With a combination of the planar magnetic model’s subtle high frequencies 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.
Newly-developed AFDS: Air Film Damping System
With conventional planar magnetic models, amplitude was an increasing low range, and the diaphragm came into contact with magnets. To solve this problem, Final took measurements by conducting diaphragm simulations using the finite element method and laser Doppler devices numerous times, and established new diaphragm braking technology known as AFDS – Air Film Damping System.
In doing so, the shortcoming of planar magnetic models – the low reproducibility of bass tones – was solved. This technology could be considered a reinvention of planar magnetic models.
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 breathe-able ear-pads, bass tone reproduction with a volume and open sound only achievable with superior dynamic models is possible.
Designed with prolonged use and ease of repair in mind
So as to make repairs and future upgrades possible, almost every part has been designed in such a way that they can be disassembled, ensuring that the product can be used for many years following purchase.
A machined aluminium magnesium alloy housing
To establish AFDS, an extremely high level of precision compared to typical driver units is necessary.
Because of this, the machined aluminium magnesium alloy housing has been machined with great precision.
By applying the kind of leather coating finish used with high-quality cameras, we’ve also taken measures against minute vibrations.
Manufactured at their own factory, this model espouses precision.
The D8000 model is manufactured at their head office 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.
Final developed manufacturing apparatus such as a diaphragm formation machine and a diaphragm tension meter in-house, specifically for the 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 controlling everything together, from sourcing the raw materials through to the assembly of the product, we have achieved high-quality products.
Newly-developed detachable cable
Final have developed a new cable for the D8000. Two kinds of cable are included – a 3.5mm mini plug type (1.5m) and a 6.3mm standard plug type (3m).
Final developed a headphone stand, for the D8000, the first such stand created by final. While compact, it is made entirely of machined aluminium. It is a stand for exclusive long-term use with the D8000.
New open type ear-pads
With not only sealed headphones but open-type headphones as well, sealing the ear-pads makes for a characteristic lengthening of reproduction frequency to bass frequencies that the driver unit originally could not reproduce. However, for the high-quality expression of the natural spread of bass frequencies the source sound originally has, it is necessary for the driver unit itself to have the ability to reproduce bass frequencies, and also to use breathe-able ear-pads that are not tightly sealed.
With all conventional planar magnetic models and many dynamic models, there is a lack in terms of bass frequencies with ear-pads that are not tightly sealed.
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 ear-pads that are not sealed tightly just with driver unit ability.
The ear-pads that great influence sound quality have been newly developed specially for D8000 from highly breathe-able foam and specialised fibres.
