Final Audio A3000 | Dynamic Universal IEMs

From Final Audio

The new staple for this price range, features a newly designed driver unit [f-Core DU] which realizes astonishingly natural sound

For the A3000 to achieve the impossibly high-quality sound for this price range requires new development and production facility. The 6mm diameter dynamic driver requires not  just  new  parts,  but  a  total  redesign  of  everything,  including  the  production machinery.    Sound  design  was  conducted  based  on  our  proprietary  sound  evaluation method  established  during  the  development  of  our  flagship  A8000  model.    A3000 delivers  astonishingly  natural  sound  with  each  sound  image  vividly  localizes  over  the comfortably and spatially spreading low-range sound.

Achievements of a new sound quality evaluation method

The  development  of  the  A  series  began  with  the  establishment  of  a  new  sound evaluation  method  by  analyzing  the  relationship  between  sound  quality  and  physical characteristics. The results came to fruition with the A8000, and the sound evaluation method evolved further with the A3000.  We listen to music recorded at various qualities at various sound levels.  Conventional evaluation methods, however, generally entail a subjective evaluation under the fixed conditions such as constant sound pressure level , and  an  evaluation  method  that  takes  into  account  the  various  practical  listening conditions that could actually occur when users evaluate the sound of various products of earphones didn’t exist. We believe that researching a sound evaluation method that made it possible to arrive at a realistic evaluation even under various different listening conditions made it possible to bring to fruition a product that can be said to be the new standard for this price range.

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.

The Feeling of a Customized Fit

Based on the chassis design that serves as an ideal solution for the IEM that become established during development of the B Series, the A3000 realizes a superior sense of fit.  Whether or not earphones offer a superior sensation of fit is determined by the sensation  of  oppression.    While  at  first  glance  it may  seem  correct  to  select  an ergonomic shape and hold it in place with the elasticity of silicone, this always places pressure on the ear which creates an unwary burden and leads to the accumulation of fatigue.  By  limiting  the  area  that  comes  in  contact  with  the  ear  in  contrast  to  an ergonomic shape that comes in contact with a large area of the ear, this product aims to  achieve  a  sense  of  fit  with  no  feeling  of  oppression.    The  green  section  of  the diagram  below  (earpiece)  is  the  1st  position,  the  blue  section  (Tragus)  is  the  2nd position, and the pink colored section (cavity of the concha) is the 3rd position which contribute  to  the  ultimate  stability  and  fitting.  For  that  reason,  it  is  suitable  for  the ears of many different people.  To the extent that there is no feeling of oppression at any of the points of contact, that makes for such a comfortable, superior feeling of a customized earphone fit.
