Commentary
A speaker system developed for the center of 5.1 ch playback of Dolby Digital, etc.
Two 8 cm cone type woofers are installed in the lower range.
This unit uses linear power technology. This method uses an edge-less structure that eliminates the edge of the diaphragm and eliminates the problems associated with conventional edge-speaker systems. This enables extremely high linearity even for large input signals and powerful sound reproduction even with small-diameter speakers.
A 2.5 cm dome-shaped tweeter is installed in the high range.
The enclosure uses Du Pont.
Uses a gold-plated speaker terminal that supports banana plugs.
