Here is a circuit suggested by my friend. But it is very old & for small tweeter. I want to use it for 40~60W compression driver(Tweeter). So it need to be more reliable & modified .
Waiting for suggestion & modifications required.

That circuit designed for DC protection and low frequency.
For tweeter protection its better to limit the amplifier input for high frequency.
Relay protector will not work, it's too slow.
