Boom, boom, boom. . . Most people associate subwoofers with contemporary hip-hop or heavy bass music. Although a subwoofer can certainly deliver powerful bass, the purpose of a subwoofer is to handle lower frequencies, such as those found in jazz, classical music, and country. Subwoofers are an important component to any high-fidelity system because it allows your speakers to handle vocals, while the subwoofer processes and delivers lower frequency sound which distributes music as the artist intended the music to be heard.
