The first natural sound speaker.
In addition to the faithful sonic reproduction referred to as "HiFi," this unit was intended to be a speaker for listening to music, and was developed independently for use on the Electone. As a sound surface source it was equipped with a diaphragm made of a special expanded polystyrene.
The NS-30 was extremely large at 1030 mm (H) × 740 mm (W) × 315 mm (D).
