Commentary
3-way speaker system.
A roll-free edge 25 cm cone woofer is used for the low range, a 12 cm cone scoker with a dumped edge for the middle range, and a 5 cm cone type tweeter for the high range.
The enclosure eliminates the boumey by applying special damping to the bass reflex duct.
In addition, the material was reexamined from the hearing test, and lauan plywood was used for the baffle surface, and homogen material was used for other parts.
Terminals and selector switches are installed to support 2 - and 3-channel multi-amplifier systems.
In addition, a continuously variable level control is mounted on the squaker and tweeter.
