The newly developed 10-mm driver uses a 5-micron-thick diaphragm made of a combination of a high-strength, special aluminium material that suppresses unwanted vibration and a supple free-edge material. The special aluminium material contributes to improved high-frequency sound reproduction, while the free-edge material lowers the lowest resonance frequency to achieve outstanding low-frequency sound reproduction. Furthermore, magnetic fluid is used in the voice coil section to maximise its characteristics to ensure high stroke accuracy of the supple-edge diaphragm and to provide a high damping effect, which were previously difficult to achieve. The result is the reproduction of sound over a wide frequency range with ultra-low distortion.
