Acoustic Horn

The acoustic horn is used to increase the overall efficiency of the driver. Most commonly used for high-frequency reproduction, the usual configuration consists of a compression driver that produces sound using a small metal diaphragm that is vibrated by an electromagnet. The compression driver assembly is then attached to the base of the horn’s throat. Well-designed horns, like the Pivot X110 horn used in the PreSonus ULT-series loudspeakers, can better control the high-frequency response throughout their coverage angle for improved off-axis response.
