Unit maintained! It looks like a plain tall boy speaker, but it's a 3-way system with a 4-speaker configuration, with an even more independent enclosure and woofer built into the enclosure. Other units also have a structure that suppresses resonance, and are characterized by sound with a sense of localization. There are line wounds and bruises in places (Kojima Yosuke)
