Commentary
A cabaret series speaker system developed for sound reinforcement.
Two newly designed 20 cm cone woofer units, 2118H, are installed in the low range.
A horn type tweeter 2404H using a bi-radial horn is mounted in the high range.
The enclosure is made of 19mm-thick rigid multi-layer plywood with a polyurethane coating on the entire surface to ensure high strength. In addition, it is equipped with a corner guard that is useful when using the stack and a handle for transportation.
A level control is provided for the high-frequency band.
The input terminal uses an M6 phone jack.
It can be installed by the separately sold stand. Also, there was a front cover as an option sold separately.
