how to make a speaker protector circuit?

This is a speaker protector circuit diagram using NE555N IC. Every brand amplifier has its own speaker protection system. But the handmade amplifier has no speaker protection in the circuit board. For this case, we have to use another speaker protection circuit. Here in this post, we can get a speaker protection circuit diagram.
