How exactly does the horn work? In fact, a horn is a sound transducer that converts high-pressure, low-volume sound waves from the driver or horn throat into low-pressure, high-volume sound waves in the horn opening or space. In other words, a horn can also be viewed as an impedance match between a high impedance acoustic wave (driver or throat) and a low impedance acoustic wave (in the horn opening or in the space). With good impedance matching, the efficiency of sound wave transmission is greatly increased. which is also the reason why horn speakers are always efficient.
Whether it is a treble horn, a mid-range horn or a bass horn, a driver composed of a strong magnet is required. Due to the high difficulty of manufacturing the drivers of the mid-range horn and the bass horn, most of the common horn speakers share a single driver for the mid-range horn and the bass horn. The mid and high-pitched horns, these horns are designed to be two-way. There are also a few horn speakers that use high, medium and low three-way channels, in which the treble and midrange use independent drivers, and as for the bass, there are few who use real horn speakers.
