Commentary
25 cm speaker unit with mechanical 2-way configuration.
There is only one voice coil, and the cone paper has a structure in which a tweeter cone is joined to the center of the woofer with a corrugation edge.
When it was changed from inches to centimeters, the model number was also changed from PIM-10 to PIM-25A.
