Diamond - the Ideal Material for Diaphragms
Diamond has excellent physical properties such as sound speed and hardness, making it the most suitable material for diaphragms. Its particularly excellent bending rigidity contributed greatly to the realization of the "ultra-low distortion DU" we aimed for this time. When observed with a laser displacement meter, even hard metal diaphragms deform in various directions, causing distortion, but in the case of diamond, its bending rigidity makes the displacement extremely small, suppressing the noise generated on the diaphragm surface. Its particularly excellent bending rigidity contributed greatly to the realization of the ultra-low distortion DU we aimed for this time. This product uses "True Diamond", which manufactures diamond foil by crystallizing diamond on silicon and then melting the silicon.
New Surround Edge
Diamond has a specific gravity of 3.5—about twice that of beryllium—posing a challenge when paired with film-type edges, which tend to collapse under the weight and exhibit rolling motion. Additionally, conventional edge materials are prone to resonances at specific frequencies, which is another unavoidable issue.
To address these problems, Final developed a new edge using a special polyurethane material. While traditional polyurethane has the drawback of being prone to degradation, this new material overcomes that weakness. It is lightweight yet offers high elasticity and flexibility, successfully resolving the conflicting demands of ease of movement and suppression of unwanted resonance.
Completion of Ultra-Low distortion DU
Through the development of the above diaphragm material and manufacturing technology, the newly developed DU equipped with a diamond diaphragm has achieved an astonishing distortion rate of less than 1/100 of the conventional model in the frequency range below 100Hz.
By reducing distortion in the ultra-low range and improving the amplitude frequency response of the ultra-low range, the reproduction of the low range has been improved to an unprecedented extent, and the overlap with the delicate and gorgeous mid-high range with good transients has also been reduced. While reproducing a huge amount of musical information with overwhelming resolution, it also achieves an amazing sense of separation that allows you to feel whichever band you focus on. In addition, since there is no distortion at all, the silence of the silent parts of the music is felt more strongly, and each sound stands out even more.
Stainless Steel Machined Housing with Côtes de Genève
The housing is made of precision-machined, highly rigid stainless steel. It is designed to firmly support the driver and suppress unnecessary vibrations, resulting in clear sound contours. The housing is also treated with a wavy precision cutting process called "Côtes de Genève." This is a sophisticated technique that is often used for the internal parts of luxury watches, not just for aesthetic reasons, but because the cutting surface is the finished dimension as is, compared to polished finishes, there is less deviation in precision.
Designed for Long Life and Easy Repair
No adhesives are used for assembling the housing or attaching the DU, but rather screws, which are difficult to design, are used, making long-term repairs possible. In addition, the fastening force of the screws firmly supports each part, suppressing unnecessary resonance.
Small Contact Area for an Excellent Fit
The comfort of earphones is determined by the feeling of pressure. Although the method of holding the earphones by using the resilience of silicone, such as selecting an organic shape that promotes ergonomics, may seem correct at first glance, it always puts pressure on the ears, which can unconsciously strain the ears and cause fatigue. Compared to a shape that contacts the ears with a large organic surface, we aimed for a fit without a feeling of pressure by limiting the contact area. Therefore, it fits the ears of many people. If there is no feeling of pressure at all contact points, you will feel how comfortable the earphones are to wear, and it is an excellent fit that feels like a customized earphone. In addition, the housing size is smaller than the A8000 , so it fits even easier in the ear.
High-Precision Silver-Coated Cable with MMCX
This product was developed in collaboration with Junkosha, which is famous for developing and manufacturing cables that pursue the transmission speed of signals for the supercomputer "K". The wire material is silver-coated OFC wire that brings together the know-how that Junkosha has cultivated over the years under the Junflon brand, and the insulation coating is ePTFE (expanded Teflon™), which bo
