Passive speakers can be regarded as "wooden box plus speakers". The advantage of this is that the sound can reach the best state without interference. At the same time, passive speakers are also speakers without an external power supply. They use speaker cables to connect to the power amplifier to make the speakers sound.

Passive speakers generally have two red and black binding posts behind them.
