Commentary
A National brand speaker system developed for MFB-based amplifiers.
There is a model with the same model number in the Technics era, but the content is a different configuration.
It has a 25 cm cone woofer for the low range, a 9 cm cone squaker for the middle range, and a 5 cm horn tweeter for the high range.
The enclosure is hermetically sealed.
