"sub") is a woofer‚ or a complete loudspeaker‚ which is dedicated to the reproduction of low-pitched audio frequencies (the "bass"). The typical frequency range for a subwoofer is about 20–200 Hz for consumer products‚ below 100 Hz for professional live sound‚ and below 80 Hz in THX-approved systems. Subwoofers are intended to augment the low frequency range of loudspeakers covering higher frequency bands. Subwoofers are made up of one or more woofers in a loudspeaker enclosure capable of withstanding
