Ранние варианты выпускались без фенольного кольца

Первые экземпляры этих ВЧ выпускались в 70-хх с фенольным кольцом с голубоватым оттенком диффузора. На примере Marantz Imperial 6G.

Интересно, что в 1973 году Eastman Sound MARTIN LABORATORY 230 MKII, 16 February 1973, made in USA установили образцы ВЧ головок как в 80хх но с маркировкой EASTMAN T-1 137 7301 with Phenolic Ring

В 1983 году в каталогах появились вновь эти ВЧ c маркировкой Tweter C050N08.

Самый последний выпуск запустили в Китае MidwestSpeaker MT-4107-4
