Commentary
Driver unit with high efficiency, wide bandwidth, and excellent linearity.
The diaphragm is made of an aluminum alloy with a thickness of 0.05 mm and is formed by the pneumatic drawing method.
The magnetic circuit uses a 44 mm edgewise wound aluminum ribbon voice coil and Alnico V magnet.
In addition, a pure silver ring is attached to the pole piece to increase efficiency in the high-frequency range and to maintain a flat response.
The back cover is aluminum die-cast with reinforcing ribs to prevent ringing resonance that causes distortion.
