What does a subwoofer mean?

　　①Does it mean only the bass effect?

　　②Does it mean the same thing as a subwoofer?

　　There are left and right channel speakers at home. There is a tweeter on the top of the speaker, and there are two 4-inch speakers on it. This should be a mid-range speaker, right?

　　The frequency range of human hearing is 20hz-20khz. In theory, the speaker needs to be able to restore the 20hz-20khz signal to meet the listening requirements. But it is very difficult to truly restore the bass, and now ordinary speakers have a lot of distortion around 80hz, let alone 20hz. And for the surround system for movies, each channel can be restored to 20hz, which requires a lot of power and the cost is considerable. So the subwoofer came out. The subwoofer can restore the bass in a targeted manner, usually around 40hz-120hz, and it is difficult for ordinary subwoofers to achieve low distortion at 20hz. In this way, the power amplifier can restore the signal below 120hz of each channel to a subwoofer. The speaker you mentioned should be a three-way speaker, divided into high, medium and low. There is a crossover circuit inside, which will divide the 20hz-20khz signal into three sections, and each section is restored by a different speaker. The 10-inch you mentioned is responsible for restoring the bass. It depends on the crossover point of your box. Generally, the three-way low frequency should be 20hz-hundreds of Hz. Generally, it starts to be seriously distorted at 80hz, so although there is a woofer, the 20-80hz signal may have been lost or distorted. Personally, I don't know if it will help you?
