A "Woofer" is a type of loudspeaker designed to reproduce low-frequency sounds, typically in the range of 20 Hz to 2 kHz. It is commonly used in audio systems, such as home theaters and car audio setups, to enhance bass performance. Woofers are essential for delivering deep, rich sound, making music and movie experiences more immersive. In many audio systems, woofers work alongside other speakers, like tweeters, which handle high-frequency sounds. Together, they create a balanced sound profile. Woofers can be found in various sizes and designs, including subwoofers, which are specialized for even deeper bass reproduction.
