A line-array-type speaker system of the Cabaret series designed as a wide range of SR systems such as small halls and banquette halls.

Two horn type tweeters 2402H are installed 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.
