My requirements for a speaker protection circuit: 1. Delayed connection of speaker after power on. 2. Instant speaker disconnection on power off. 3. Quick speaker disconnect in case of DC on amplifier output. 4. Latch relays off when any fault occurred. 5. Can be used for my dual mono design without hard wiring ground of the two amps together.
Speaker protector circuit diagram using NE555N Electronics Help Care
$99 The Guardian-86 is a high-end protection circuit designed to protect speakers against two common ways that power amplifiers can misbehave: Sharp voltage transients on power-up and power-down, resulting in annoying clicks and pops in the speakers.

Speaker Protection Circuit (Stereo) This is the speaker protection circuit, provides stereo speaker protection and prevents switch-on clicks and DC components on the output of the amplifier connected. Speaker Protection Components List: R1,R2 : 3K3 R3,R4,R5,R6,R7 : 8K2 R8,R9,R10,R11 : 330K R12,R13 : 18K
Speaker protection circuit kit
The speaker protection circuit detects the DC voltage at the amplifier output and disconnects the speaker. The DC voltage detection level of the protection circuit is very low (0.7…1V) so that the speaker is protected from being exposed to high voltage.
The tweeter speaker protection circuit
Loudspeaker DC protection is always something of a mixed bag. Units such as Project 33 are well behaved and will offer a high level of protection for the speaker. Should the amplifier fail, the most common failure mode is for an output device to short-circuit, causing the output to swing to one supply rail or the other.

Speaker Protection Circuit (Connexelectronic) Hifime Audio
uPC1237 is a well known IC used for protecting the speakers form DC as well as amplifiers from over current. Almost any Sony amplifier starting from the lower range and right up to the higher-end ES series are using this chip. So I thought was a good idea to make a stand alone module which could be used by the DIY community.
