Commentary
Coaxial 20 cm speaker system.
The low range part is a 20 cm diameter cone with a free edge of the cone made of Kapok.
The free edge reduces fo and improves the low range.
The high-frequency part is a horn type.
The crossover frequency is set to 2,400 Hz in order to improve directional characteristics and eliminate distortion caused by the split vibration of the woofer.
