Tweeters are relatively small speakers that emit the “upper” range of sounds used for reproducing music and speech called “trebles.” Woofers and subwoofers cannot produce the same sounds that tweeters can due to their construction and cone sizes.

Do tweeters count as speakers?

As tweeters produce high-frequency sounds, in cars they're used as part of a speaker system in cars but not alone. They're used alongside others like component speakers or to compliment and improve what's already there.

What is the difference between speaker and tweeter?

Think of a tweeter as the high-pitched tweeting of a bird. The tweeter is the smallest driver unit in a speaker design and is responsible for reproducing the highest range of frequencies. This range is often within 2 kHz to 20 kHz though some specialty tweeters can produce sound waves as high as 100 kHz.
