A type of loudspeaker driver called a super tweeter is made to reproduce high-frequency sound outside the normal tweeter's frequency range. They frequently function over 10 kHz and can reach up to 100 kHz, much above the human hearing threshold. Super tweeters can be a hidden weapon for high-fidelity music, despite some people's doubts about their usefulness.

One explanation is that they make high-frequency sound reproduction more accurate and detailed. High-frequency harmonics are produced by many musical instruments, including triangles and cymbals, and they are crucial for accurate and realistic sound reproduction. Super tweeters may pick up these harmonics and give the music a level of depth and clarity that is frequently lacking when they are absent.

The entire sound of a system may be balanced with the aid of super tweeters. Without them, the system's frequency response might be uneven and place an undue focus on mid-range frequencies. Super tweeters may fill up the voids and produce a more even tone.

A sense of roominess and depth may be added to the music using a super tweeter. Super tweeters may produce a more realistic and lifelike listening experience by recreating high-frequency sound, which is sometimes lost in regular speakers.
