Final D8000 Headphones

With conventional planar magnetic designs, the diaphragm excursion is limited, and the diaphragm easily contacts the magnets. To address this issue, Final performed extensive measurements using finite element method and laser Doppler simulations of the diaphragm, and developed a new diaphragm damping technology known as AFDS – Air Film Damping System.

By doing so, the defect of planar magnetic models which was the poor extension in the low range was solved, this technology could be considered a reinvention of planar magnetic models.

With the D8000, the problem of the diaphragm coming into contact with the magnets has been solved through the AFDS (Air Film Damping System), and it has been possible to extend the minimum frequency that the driver unit can reproduce. In combination with the open ear cups, the D8000 reproduces low frequencies like the best dynamic models.

To enable repairs and future upgrades, almost all parts have been designed to be disassembled, ensuring that the product can be used for many years after purchase.

To use AFDS, an extremely high level of precision is required compared to typical driver units.
For this reason, the aluminum-magnesium alloy housing has been machined with great precision.
The upholstery is made of high quality leather, and every little detail has been taken care of in order to absorb even the slightest vibrations.

The D8000 model is produced at our Kawasaki headquarters. Along with the precision of the individual parts, the assembly process has been obsessively cared for, where nothing is left to chance. In order to be able to control even the smallest irregularities, the assembly jigs are designed and built in Final.

To achieve equal performance for all specimens with the minimum tolerance in Final have developed a machine for forming and one for measuring the diaphragm tension, specific for D8000.

To create excellent products, you need to get to the heart of the production process. The good thing about “made in Japan” is that in Japan, companies collaborate, from the procurement of raw materials to assembly, resulting in high-quality products.

We have developed a dual cable for the D8000, one comprising a 3.5mm mini jack (1.5m) and the other a standard 6.3mm (3m).

Cable length: 1.5m
Input: 3.5mm, 3-pole
Output: 3.5mm, 2-pole with locking function
Compatible models: D8000/D8000 Pro Edition, SONOROUS VIII/VI/IV/III/II

Cable length: 3m
Input: 6.3mm, 3-pole
Output: 3.5mm, 2-pole with locking function
Compatible models: D8000/D8000 Pro Edition, SONOROUS VIII/VI/IV/III/II

With any type of headphones, sealing the earcups provides an extension of the lowest frequency that the driver unit would not otherwise be able to reproduce. Of course, the headphones must be able to reproduce low frequencies, and must also have breathable earcups. Many planar magnetic and dynamic models lack low frequencies precisely because the earcups are not hermetic.

With the D8000, thanks to the low-frequency extension via AFDS, it has become possible to reproduce the extreme lows even with non-hermetically sealed ear cups. The ear cups supplied with the D8000 have been specially developed using highly breathable foam and special fibres.
