ACT05

The "ACT05" is equipped with the proven "Mirrinx composite driver with Japanese beryllium thin film dome" for the diaphragm, and optimizes the acoustic tuning by combining it with an acoustic chamber body made of CNC-cut OFC (oxygen-free copper). The bass peak of the tuning used up until now has been further lowered, creating not only the width of the sound field but also the depth, producing rich music.

The ACT05  uses OFC material, which is copper with a purity of 99.99% or more and does not contain any oxides.

Due to the nature of the material, oxidation (rust) begins the moment it comes into contact with air, so the OFC chamber is coated with a coating that slows down oxidation. However, in principle, oxidation begins during processing, and black spots (oxidation) may be visible in some areas. Currently, it is very difficult to completely prevent the occurrence of these black spots, so this is not a defect.

Furthermore, although the above coating makes it less likely for black spots to change over time, due to the characteristics of the product, we recommend wiping off any dirt, such as sebum, that has accumulated on the product with a dry, soft cloth after use.

*Using cleaning agents, compounds, hard cloths, etc. may cause the coating to peel off and oxidation to spread rapidly.
