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.
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, 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.
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 aluminum magnesium alloy housing
To establish AFDS, an extremely high level of precision compared to typical driver units is necessary.
Because of this, the machined aluminum 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 our own factory, this model espouses precision.
The D8000 model is manufactured at our 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.
Newly-developed open type earpads
With not only sealed headphones but open-type headphones as well, sealing the earpads makes for
a characteristic lengthening of reproduction frequency to bass frequencies that the driver unit originally couldn't 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 breatheable earpads 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 earpads
that are not tightly sealed.
