National SB-12

Commentary

This speaker system is designed with an emphasis on listening as well as theory.

A 16 cm cone type woofer is installed in the low range.
This unit is designed to show excellent low-frequency characteristics when installed in a small cabinet. By using a newly developed roll edge made of special cloth for the edge part, it is strong even in large amplitude and has low fo and good low-frequency reproduction with good damping characteristics.

A 5 cm cone type tweeter is installed in the high range.

The enclosure is a closed bookshelf type.
Unlike conventional closed-type enclosures, the use of screws is minimized and a special integrated structure improves the degree of sealing. Each unit is also sealed with putty after being attached to a baffle plate to prevent air leakage.

The front net is removable.

It seems that there were the early model and the late model with slightly different logo positions.
