One of the primary functions of any subwoofer is to handle low-frequency sounds, often referred to as bass. These low tones provide depth and richness to audio content, making it more immersive. The human ear is not as sensitive to low frequencies as it is to midrange or high tones, so a subwoofer compensates by amplifying these sounds. JBL subwoofers, in particular, are designed to reproduce bass with clarity and precision, ensuring that every thump and rumble is felt as much as it is heard.
