Commentary
A bookshelf type speaker system using a special bass reflex system.
The low range has a 21.3 cm cone type woofer specially designed for bass reflex.
It uses a voice coil that thoroughly pursues low distortion. In addition, it uses free edge obtained by special molding of non-woven fabric for the edge, which suppresses distortion and enables low sound reproduction with good rise and elongation.
Equipped with a 14.2 cm cone type squaker in the middle area.
This unit achieves excellent piston motion by reducing the fo and eliminating the generation of split vibration in the audible band.
A 9 cm cone type tweeter is installed in the high range.
The enclosure uses a duct with a special shape created through repeated cut-and-try operations.
