Commentary
High Power Series 4-way bookshelf speaker system.
A 30 cm cone type woofer is installed in the low range.
Various characteristics have been improved by using long travel voice coil and skybar edge.
Two 12 cm cone type skokers are mounted in the middle area.
By using a dome radiator made of Super Duralumin, the connection to the high-frequency range is improved, and by using a newly developed damper to apply appropriate braking, flattening is achieved.
In addition, by adopting a completely sealed frame system, the influence of the back pressure of the woofer is reduced.
A 9 cm cone type tweeter is installed in the high range.
This unit uses a voice coil made of aluminum wire.
A horn type Super Tweeter is mounted for the super high band.
This unit uses a film diaphragm and realizes high-frequency reproduction up to 25 kHz by reducing the weight of the vibration system.
Equipped with 4-step switching type tone control.
This can be switched between Sharp, Normal (Popular), Normal (Classic), and Soft.
The enclosure uses a bass reflex method and has a walnut polyurethane finish on the exterior.
