What is a tweeter?

A tweeter is a type of loudspeaker driver designed to produce high-frequency sounds or treble. It is responsible for producing sound frequencies up to the upper limit of human hearing, usually around 20 kHz. The design of tweeters can vary greatly, but they typically use lightweight materials such as silk, polypropylene, or metal, which can vibrate at high frequencies. Some tweeters may also use different technologies such as planar magnetic drivers or ribbon tweeters to produce high-quality sound. Tweeters can be found in various audio systems, including home theater systems, car audio systems, and professional audio equipment. They are often paired with a woofer or a subwoofer to cover the full range of frequencies.
