In plain English: A subwoofer is a special speaker that plays only very low bass sounds to make music and movies feel deeper and more powerful.
"The subwoofer boomed with thunderous bass during the movie scene."
Usage: A subwoofer specifically reproduces very low-pitched sounds like deep bass tones that standard speakers cannot handle effectively. You will typically find it paired with larger main speakers in a home theater system rather than used as the sole audio output device.
The word combines the prefix sub- with woofer to describe a speaker designed specifically for low bass frequencies. It entered English as a technical term for this specialized audio component.
