Commentary
A 30 cm special cone type full range speaker unit slightly smaller than 420A.
This unit is called a bi-flex speaker, and consists of a large cone and a small cone with different stiffness integrated into a multi-dumped corrugation, enabling playback with less distortion in the ultra low, mid low, and mid range included in the program source.
Also, in the center of the cone, the dome radiator made of light alloy is in charge up to the upper limit of the high range.
A strong aluminum die-cast frame is used for the frame part to suppress distortion due to aging and resonance due to cone vibration.
