As we just mentioned, tweeters are the opposite of woofers. They can be built into the speaker or be standalone elements, and dedicate themselves to emitting high frequencies (from 3000 to 20000 Hz). From a technical perspective, they are speakers capable of reproducing the last three octaves out of the eleven in the hearing range.
Oddly enough, only young, healthy ears can fully enjoy this type of component—or at least those that cover the full hearing range mentioned above. We lose our ability to perceive high frequencies as we age, which is why you may not be able to appreciate the last half or the full final octave. » learn more
