Commentary
A center speaker system that uses a CD horn to clarify sound localization.
Two 12 cm cone type woofers are installed in the lower range.
A 2.5 cm dome type tweeter and a CD horn are mounted in the high range.
The CD (Constant Directivity) horn is a dome type tweeter with wide directivity. A short horn is attached to the front surface. It has sharp directivity in the direction of the short diameter (up and down), and good directivity is obtained for a predetermined radiation angle in the direction of the long diameter (left and right). In addition, the horn neck has an elliptical shape to add acoustic restriction to the diaphragm, reducing distortion and improving sound quality.
It has a magnetic protection design and can be placed close to CRT etc.
The enclosure uses a bass reflex system.
