Fostex's classic full range unit. This unit is highly regarded not only domestically, but also from overseas. It uses a high-rigidity die-cast aluminum frame and a large, strong ferrite magnetic circuit. I definitely want you to enjoy combining it with a backload enclosure. There are smudges and terminal solder marks around the label (Daiki Goto)
