Commentary
This speaker system uses a newly developed cone cave unit.
A 20 cm cone woofer using cone cave technology is installed in the low range.
In the cone cave speaker, the part that used to be a dust-proof cap in the conventional unit is positively utilized, and a concave diaphragm made by mixing special chemical fibers is used, which suppresses the disturbance of high frequency and prevents the sound from becoming muddy near the crossover.
A 3-cm dome type tweeter is installed in the high range.
Equipped with a 3-step switching type level control for high frequency.
The enclosure is hermetically sealed.
