Commentary
Wide range driver unit with flat and low-distortion design over a wide range.
A high-precision pure titanium diaphragm with a thickness of 0.05 mm is used for the diaphragm, and in combination with diamond suspension with excellent linearity, wide response and input resistance characteristics are improved.
