A 12-inch Alnico model with a green frame from Artec. A light and momentum tone typical of Artec. Smaller than 15 inches, so you can expect good sharpness. The enclosure also changes a lot, so it's a unit that is worth playing with in various ways. As for the appearance, dirt marks and scratches on the frame part can be seen on the surface of the cone paper. Serial 361723/391723 (Satoshi Yonejima)
