The speakers (drivers) used in the subwoofer are designed to work in the lowest frequency range. In structure, they are similar to but different from the bass speaker in the multi-channel speaker.
The subwoofer limits the upper limit of the working frequency to about 120-150 Hz, and has a high slope filter (3 to 4 orders)
