Compact Arrays of High Power Horn Drivers for Generating Intense Sound Fields
The development of a high power horn driver is described including the significant factors affecting mechanical stresses and temperature rise. The application of this driver to several compact arrays of multiple throat horns is illustrated. Individual drivers can be made with power rating of 60 watts program material. Multiple throat horns for 4, 6, 12 and 24 units have been developed. The efficiency over the range significant to speech is of the order of 35%.
