Circuit-delay relay circuit speakers is useful as a delaying / delay on the speaker that functions as a deterrent to prevent pounding of the very first amplifier is turned on. This aims to avoid memperawet speakers easily damaged.? The following is a schematic drawing :

The time needed to re-open relay if the current cut off about 0.5 seconds. Or you can try to use the circuit scheme below:
