Commentary
This is a bookshelf type speaker system that uses a boron diaphragm in the middle range.
A 22 cm cone type woofer is installed in the low range.
R. I. (radial injection) carbon cone is used for the diaphragm, and ideal diaphragm shape is obtained by radial molding of high rigidity carbon fiber mixed resin.
Equipped with 5 cm cone type skoker in the middle area.
Boron is used in the center diaphragm of the Skoker to realize excellent characteristics such as suppression of natural sound.
A 1.6 cm dome type tweeter is installed in the high range.
By using a full-scale input terminal and network, the sound quality is improved.
The enclosure uses a rear bass reflex system.
A 4-sided round baffle with four corners of the front baffle rounded reduces diffraction phenomena at the baffle.
There was a special speaker stand sold separately.
