Secret recipe beryllium-copper film, containing 16.7 % beryllium and 83.3 % copper, which enables the film to be extremely thin while being less prone to breakage than pure beryllium film. With a thickness of only 0.015 mm, it far surpasses aluminum film at 0.04 mm and titanium film at 0.03 mm. Paired with a patented metal dome structure, it offers exceptional analytical power, blending the characteristics of metal and silk films, providing strong resolution, being pleasant to listen to, without the sharp peak of high-frequency ear fatigue, and having better extension with a frequency upper limit reaching 40K.
It features a 104*4mm thick precision-machined aluminum panel with a protective mesh, Y35 high-performance magnets, anti-magnetic, and cooling magnetic fluid. It also has a 0.15 mm copper short-circuit ring and a large sound-absorbing cavity.
