Sonus Aeterna is a unique company based in Greece, which designed and manufactured the very sensitive – ultrahigh fidelity Horn Loudspeakers. Here are few of their loudspeakers products and projects.
One more major proof about the necessity of a matching transformer (this is the closest analog to the horn speakers), is our ears. The nature’s horn device. Our ear is a horn device which couples our inner diaphragm into the air. We are all hear through two directional horns. Horn loading can be thought as the acoustic analog, matching the driver’s diaphragm to the air. The acoustic analog of the output tube is the driver (speaker). The analog of the speaker’s load is the air and the acoustic analog of the output transformer is the horn device. The equivalent function of the horn is to work as an acoustic transformer, matching the driver’s high density diaphragm to the air’s low density mass. Horn loading gives the best coupling between the driver’s
