Commentary
Semi-hard domed mid-range.
The diaphragm is made of a highly elastic material with no natural resonance, and is double coated with a damping agent to achieve a low distortion factor.
CCAW is used for the voice coil, and by maintaining the optimum mass balance with the diaphragm, the high range limit is expanded and the transient characteristics and resolution are improved.
Uses a large 100 φ ferrite magnet for the magnetic circuit.
The use of square rigid duralumin panels prevents resonance. In addition, the exterior is treated with special treatment after hairline treatment to bring out the goodness of the material.
