Maintained in October 2021! This is a monitor speaker 612C that has been refined from the masterpiece 612A system. The unit is an early model 604-8G. The thick, unsluggish tone centered around the middle range is perfect for vocals. Since the localization is also precisely determined, it is a practical and easy-to-use speaker. The exterior has small scratches and a feeling of use such as dullness. Serial 02122 02141 (Yamato Yuki)
