Advanced Technology Metal mesh stators working close to the ultra-fine diaphragm offer superior openness and minimize distortion. Frames incorporate special alloys to ensure sonic stability and reduce distortion. The width of the mesh grating is only 50um so that sound waves below 1 million Hertz can pass through, making it acoustically transparent.
