What does subwoofer mean?
A subwoofer is a loudspeaker designed to produce low-frequency sounds, particularly the deep bass found in music, film soundtracks, and electronic effects. Its name combines the prefix “sub-,” meaning below or beneath, with “woofer,” a term for a loudspeaker driver that reproduces low frequencies. A subwoofer may appear as a separate box in a home-theatre or stereo system, or it may be incorporated into a larger speaker enclosure. Its controls often allow listeners to adjust volume, crossover frequency, and phase, helping the low-frequency output blend with the main speakers. Although some listeners describe the most prominent bass as “treble,” subwoofers are principally associated with frequencies below the midrange rather than with that higher register. The word is common in technical discussions of audio equipment as well as in everyday descriptions of entertainment systems.
nounA loudspeaker designed to reproduce very low-frequency sounds, especially bass frequencies. It may be a separate unit connected to a main audio system or a component built into a larger speaker.

Where does subwoofer come from?
“Subwoofer” is a compound formed from the prefix “sub-,” meaning below or under, and “woofer.” The term “woofer” was coined in the early 20th century for a loudspeaker driver intended to reproduce low-frequency sounds. The compound “subwoofer” developed later to distinguish a dedicated bass speaker or driver from more general-purpose loudspeakers and from the individual woofer component.
How subwoofer is actually used
The term is standard in consumer audio, sound engineering, and home-cinema contexts. In informal use, it may refer to either a complete subwoofer unit or the low-frequency driver itself, though these are technically different components.
Easily confused with subwoofer
A subwoofer is usually a complete loudspeaker unit, whereas a woofer is the individual driver within a speaker enclosure that produces low-frequency sound.
