The term 'Woofer Range' is used to describe the range of BASS frequencies that a woofer can produce. A woofer is a type of loudspeaker that is designed to reproduce low-frequency sounds, such as BASS and sub-BASS. The woofer range is typically between 20 Hz and 200 Hz, although some woofers can reach frequencies as low as 10 Hz. Woofers are commonly used in home audio systems, car audio systems, and professional sound systems.
