Commentary
A speaker system using a collagen diaphragm.
A 25 cm cone woofer is installed in the low range.
The corn uses a collagen fiber that is fused with corn paper after a special chemical treatment of animal skin. By giving appropriate internal resistance, resonance of peaks and dips is suppressed.
The mid-range is equipped with a 12 cm cone type squaker that uses a collagen speaker as well as the low-range.
A horn type tweeter is installed in the high frequency range.
Level control is mounted on the front.
