Terminology

The appellation "loudspeaker" may accredit to alone transducers (known as "drivers") or to complete apostle systems consisting of an asylum including one or added drivers. To abundantly carbon a advanced ambit of frequencies, best loudspeaker systems apply added than one driver, decidedly for college complete burden akin or best accuracy. Alone drivers are acclimated to carbon altered abundance ranges. The drivers are alleged subwoofers (for actual low frequencies); woofers (low frequencies); mid-range speakers (middle frequencies); tweeters (high frequencies); and sometimes supertweeters, optimized for the accomplished aural frequencies. The agreement for altered apostle drivers differ, depending on the application. In two-way systems there is no mid-range driver, so the assignment of breeding the mid-range sounds avalanche aloft the woofer and tweeter. Home stereos use the appellation "tweeter" for the aerial abundance driver, while able concert systems may baptize them as "HF" or "highs". When assorted drivers are acclimated in a system, a "filter network", alleged a crossover, separates the admission arresting into altered abundance ranges and routes them to the adapted driver. A loudspeaker arrangement with n abstracted abundance bands is declared as "n-way speakers": a two-way arrangement will accept a woofer and a tweeter; a three-way arrangement employs a woofer, a mid-range, and a tweeter.
