National SB-35

Commentary

A floor type sealed speaker system.

In the lower range, 25 cm cone type woofer developed for small cabinet is mounted.
By adopting a yoke with high magnetic permeability, it is possible to reproduce low-frequency sound with a margin with damping.

A 9 cm cone type squaker is mounted in the middle range, and a 5 cm horn type tweeter is mounted in the high range.

The enclosure is designed to be completely sealed with no air leakage and uses a wide range of sound absorbing materials to enhance the damping effect.

Walnut is used for the exterior, and calming tone net and metal sash are used for the front.
Also, there seems to have been a first term model and a second term model with slightly different logo positions.
