Self-made enclosure. The enclosure uses 20mm thick solid board for the baffle, and the exterior is a well-made enclosure with veneer. It seems that a 4-inch unit can be used for the woofer section, and one with an aperture of up to 78 mm can be used for the tweeter part. The exterior is dull, dirty, small scratches, etc. (Takahashi Nobuyuki)
