supertweeter

A supertweeter is a specialized type of loudspeaker designed to reproduce the highest frequencies within the audible spectrum, extending beyond the range of a standard tweeter. Loudspeakers, in general, convert electrical energy into sound waves. This is achieved by a motor, often a voice coil, which vibrates a diaphragm. This vibration creates sound waves that correspond to the original electrical signal, such as speech or music.

Because a single loudspeaker cannot fully cover the entire range of audible frequencies (approximately 20 to 20,000 hertz), different types of speakers are used. A woofer handles low frequencies, a tweeter handles high frequencies, and a midrange speaker covers the middle range. Supertweeters and subwoofers are used to reproduce the extreme ends of this spectrum.1
