Hornhøjttalere

Hornhøjttalere, also known as horn speakers, are a type of loudspeaker that uses a horn to enhance the efficiency and directivity of the driver. The horn acts as an acoustic transformer, matching the impedance of the driver to the impedance of the air. This impedance matching allows for more efficient transfer of acoustic energy, resulting in higher sound pressure levels with less power input compared to direct-radiating speakers.

The horn shape is crucial to its function. Typically, it flares outwards from a small throat, where the driver is mounted, to a larger mouth. This flare increases the effective radiating area and controls the dispersion pattern of the sound. Different horn shapes, such as exponential, conical, and hyperbolic, are employed to achieve specific frequency responses and directivity characteristics.

Hornhøjttalere are known for their high sensitivity and dynamic range, making them capable of reproducing sound with great impact and detail, even at low listening levels. Their inherent efficiency also means they can be driven by lower-powered amplifiers, which can be beneficial in certain applications. However, achieving smooth frequency response across a wide range, particularly in the lower frequencies, can be a challenge. The physical size of the horn, especially for low frequencies, can also be a significant consideration in terms of placement and aesthetics. Despite these challenges, hornhøjttalere remain a popular choice for audiophiles and professionals seeking high-efficiency and dynamic sound reproduction.
