DIATONE P-62F

Commentary

This speaker unit was completed in 1947 through joint development with NHK engineers at Diatone and was adopted for NHK monitors.
It is displayed at the Broadcasting Museum in Mount Atagoyama as the first domestic monitor speaker.

It adopted corrugation and was produced as the first Diatone's unique matched resonant full-range speaker, and became the prototype of P-610.
