Line 1:

A '''compression driver''' is a type of [[loudspeaker]] driver which uses the technique of "compression" to achieve high efficiencies. In this context compression refers to the fact that the area of the loudspeaker diaphragm is significantly larger than the aperture through which the sound is radiated. Compression Drivers are most commonly used in high [[sound pressure]] level applications. They are normally used in conjunction with [[Horn (acoustic)|acoustical horns]]. Horn-loaded Compression Drivers can achieve extremely high efficiencies compared to direct-radiating loudspeakers. The efficiency can even pass 100%, which is due to the way it is measured in loudspeakers. They are almost universally used for high frequency reproduction in high power sound reinforcement loudspeakers.
