Tweeter
open-in-new
<p>A tweeter or treble speaker is a special type of <a href="/facts/Loudspeaker/tqEjnJ2z">loudspeaker</a> (usually dome, inverse dome or horn-type) that is designed to produce high audio frequencies, typically from 2,000 to 20,000 <a href="/facts/Hertz/6Wshj5qm">Hz</a>. The name is derived from the high pitched sounds made by some <a href="/facts/Bird/RJF6zwLP">birds</a> (tweets), especially in contrast to the low woofs made by many <a href="/facts/Dog/DvQVRVzy">dogs</a>, after which low-frequency drivers are named (<a href="/facts/Woofer/cTSN55j0">woofers</a>). </p>
