Woofer

Definition

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 to handle bass and sub-bass frequencies.

5 Must Know Facts For Your Next Test

1. Woofers are essential for reproducing low-frequency sounds, which are crucial for the depth and richness of audio.
2. The efficiency and performance of a woofer depend on its size, material, and design.
3. Sound waves produced by woofers travel slower than high-frequency sound waves due to their longer wavelengths.
4. Woofers often use large cones to move more air, which helps in producing deeper bass sounds.
5. The enclosure or cabinet that houses the woofer significantly affects its sound quality by influencing resonance and vibration.
