Maintained! A consumer aircraft developed as a tall boy based on the BBSM series. Two 25cm woofers are placed to ensure low frequencies. A dynamic sound that you wouldn't think of as a tall boy, combined with high efficiency. The low range with a low center of gravity, which sets it apart from the light low frequencies of recent speakers, is attractive. There is a line scratch on the side plate on the exterior. Serial 425 426 (Yonejima Satoshi)
