Tall boy type 3-way speaker system.
Two 20 cm cone type woofers with carbon fiber diaphragm are installed in the low range.
By making it a double woofer type, the low sound reproduction ability is improved.
It is equipped with a 5 cm dome type squaker in the middle range and a 2.5 cm dome type tweeter in the high range.
These units use polyimide resin diaphragms that have undergone a titanium vapor deposition process.
The enclosure is hermetically sealed.
In addition, walnut natural wood is used for the whole exterior finish.
