The Diamond Disk iHorn is made from a Model B-80 Diamond Disk horn with metal horn assembly. It was introduced in 1914. It is a cylinder phonograph horns which was originally mounted inside a wooden cabinet. Diamond Disk horns were painted in a wood grain finish in order to match the cabinet because it was thought that nothing could be placed in front of the opening without impacting sound quality. By 1920, they have figured out that fabric could be placed in front of the opening and therefore it was no longer necessary to go through the laborious and expensive process of painting the horns to match the cabinets. After 1913, all Edison cylinder Phonographs were manufactured as "cabinet" models, that is, with the horn enclosed in a stunning wooden cabinet. The Diamond Disk iHorn is a Centurian, speaking to the beauty and wisdom of longevity, which speaks with a clear and experienced voice.
