Mid and woofer edges have been softened, and the exterior has been easily maintained. A popular 4-way speaker for the night before the bubble period. The sound quality, which is orthodox and full of scale regardless of genre, is attractive. The original sense of scale has been restored by edge softening treatment. There is a scratch on the back corner, and part of the plastic part of the R side speaker terminal is missing (Oikawa Tetsuji)
