Commentary
This 2-way speaker system is based on the same concept as the advanced S-180.
A 27 cm cone type woofer is used for the low frequency band to increase the resolution of the sound at the time of large input.
A 6.6 cm balanced drive type tweeter is used for the high range.
B-alloy (boron alloy) diaphragm is used for the diaphragm.
The unit layout of the enclosure is symmetrical to improve sound localization.
