Commentary
This is a floor-type speaker system that uses a tall boy type with excellent space factor.
It has two 16 cm cone woofers in the low range, two 7 cm cone midrange woofers in the middle range, and a 2.5 cm balanced drive tweeter in the high range.
One of the two mid-range units is located on top of the front baffle and is a rotating unit that can be reoriented to match screen movement and surround mode to create an ideal sound field.
The enclosure is designed with a bass reflex.
