The different types of loudspeaker horns include exponential horns, conical horns, tractrix horns, and hyperbolic horns. Each type has its own design and characteristics that affect sound dispersion and frequency response.

A number of symmetrical, narrow dispersion, usually exponential horns can be combined in an array driven by a single driver to produce multicell horns.

A horn with a flare constant of 1.0 is a true exponential horn, while a flare constant less than 1.0 is a hyperbolic-exponential horn. As the flare constant goes lower, the horn flares more suddenly at its mouth (in a full-size horn).

Mar 22, 2017 · The most notable differences have been the exponential midrange horns of the Klipsch Heritage series vs. the modified tractrix horns--the K-510 and the K-402, and the other modified tractrix designs on the Forte II, Chorus II, Quartet, etc.

Figure 5.1 shows the minimum geometry required to define an exponential horn. The area at the throat S0, the area at the mouth SL, and the length L are used to calculate the flare constant m of the exponential horn. The exponential horn geometry is described by the following expression.

In the world of horn design, exponential horns are known for providing excellent loading properties, while conical horns have poor loading but excellent directivity control. How Does A Horn Amplify Sound?

An exponential horn flares at a smoothly increasing rate as sound moves from the driver toward the mouth. The hyperbolic horn adds the flexibility to fine-tune the shape and achieve even better characteristics. For a hyperbolic horn, the area increases along the horn axis in accordance with the following expression:

Exponential Horns:Exponential horns are those where the horn length is exponentially related to the horn area. The expression for an exponential horn is: S = S1e mx S = the area at the horn mouth S1 = the area at the horn throat m = the flare constant x = …

The Constant Directivity horn flare had three distinctive regions, each with a specific purpose. Adjacent to the compression driver, was an exponential flare designed to provide acoustic loading. Moving outwards from the exponential throat section is a section with conical flare (i.e., straight side walls).

May 1, 2017 · The exponential horn is known as the shape realizing the best matching between a source and the external field for frequencies higher than its cut-off frequency. In practice, the horn being of finite length the effective cut-off is significantly higher and resonances appear as waves are reflected at the end of the horn.
