What’s the tweeter?
A tweeter or treble speaker is a special type of loudspeaker
(usually dome or horn-type) that is designed to produce high audio
frequencies, typically from around 2,000 Hz to 20,000 Hz (generally
considered to be the upper limit of human hearing). Specialty
tweeters can deliver high frequencies up to 100 kHz. The name is
derived from the high pitched sounds made by some birds, especially
in contrast to the low woofs made by many dogs, after which
low-frequency drivers are named (woofers).
Most tweeters are designed to reproduce frequencies up to the
formally defined upper limit of the human hearing range (typically
listed as 20 kHz); some operate at frequencies up to approximately
30 kHz. Tweeters with a greater upper range have been designed for
psychoacoustic testing, for extended-range digital audio such as
Super Audio CD intended for audiophiles, for biologists performing
research on animal response to sounds, and for ambient sound
systems in zoos. Ribbon tweeters have been made that can reproduce
80 kHz and even 100 kHz.
