What is a subwoofer?

what is a subwoofer

A subwoofer, also sometimes called a sub, is a type of loudspeaker driver designed to produce low-frequency audio known as bass. Subwoofers for both car and home use typically have a frequency output range somewhere around 30 to 150 Hertz.

The name “subwoofer” is also commonly used to refer to a speaker driver installed in a matching speaker enclosure, sometimes with a pre-installed amplifier for home theater use. Although their cones can vary by speaker size, subwoofers require a larger cone size to produce lower bass frequencies due to the larger wavelength size of low frequency sound.

Subwoofers are often used to fill in the lack of bass performance from main speakers, small speaker drivers, and especially to make use of the dedicated bass channel in surround sound media.
