tweeter
n. countablen. a small speaker that is designed to play only high-pitched sounds. You usually find these in high-quality headphones or speakers to make the sound clearer.
n. a high-frequency loudspeaker driver designed to reproduce the upper range of the audio spectrum. Typically smaller in diameter than a midrange or woofer to ensure accurate reproduction of treble frequencies.
The tweeter makes the music sound much clearer.
To improve the sound quality of the home theater system, the technician replaced the old tweeters with higher-quality models.
In a multi-way speaker system, the tweeter is often mounted in a separate enclosure or baffle to prevent acoustic interference from the larger drivers that handle midrange and bass frequencies.
From to tweet + -er.
