Featuring the completely redesigned [f-Core DU] driver unit, which entails new design, parts and production technology.
In order to achieve sound quality impossible at this price range, we newly developed 6mmφ [f-Core DU] dynamic driver unit from the scratch. To realize the brand new driver, we established new production facility overseas and newly designed not only parts for the driver unit such as diaphragm, voice coil, magnet, magnetic circuits, adhesives, but also the production machinery used in the manufacturing process. As material for the driver front housing, rather than the traditional aluminum, we used brass, a material that is both highly resistant to the effects of magnetism and also boasts a high specific gravity. In order to increase the time response characteristic of the diaphragm, the voice coil employs a 30μ ultrathin CCAW, and a minimum of adhesive is used for assembly to thoroughly lighten the moving parts. Moreover, the diaphragms are neatly pressed in small lots of roughly 1/3 the normal size in order to constrain pressure deviation to a minimum and realize uniform shaped diaphragm with no deformation.
