Horns are an important component of high output audio systems. Their combination of efficiency and pattern control makes them nearly indispensable tools for projecting midrange and high frequencies, especially over longer distances. A properly designed and implemented horn will deliver focused, predictable performance to its designated zone of coverage.
There are horn designs available in a variety of shapes, sizes, coverage characteristics, and construction materials. Besides the need to select a horn according to its intended purpose, it is necessary to match the horn physically with the mounting requirements of a given driver.
