What is a Moofer?

This parameter is mainly for packaged speakers. The woofer is a woofer unit in a car speaker, and its role is to reproduce the low frequency signal (frequency range is generally 20Hz-150Hz) output from the frequency divider. Generally speaking, the larger the diameter of the woofer, the diameter of the magnet and the voice coil, the better the low-frequency playback performance and transient characteristics, and the higher the sensitivity.
