Speaker protection circuit with PCB layout
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.

Simple Speaker Protection Circuit for Power Amplifiers with Balanced Outputs XEN Audio October 2013 Introduction If one search on the internet, one would find tons of speaker protection circuits for single-ended power amplifiers. There are also simple-to-use ICs designed for the purpose, like uPC1237 or TA7317, but
Speaker Protection and Muting with an Optical Coupler Nuts & Volts Magazine
A speaker protection and muting circuit is installed between a DC coupled audio power amplifier output and the speaker. Its main purpose is to disconnect the speakers as soon as a large DC voltage that can damage the speaker is present at the output of the amplifier. This can happen when the amplifier is malfunctioning.
Speaker protection circuit
Feb 7, 2020. #3. A protection circuit monitors the output offset voltage, and will usually disconnect the speakers if the offset voltage exceeds about 1 volt. In addition they usually monitor output transistor currents and will 'trip' if the current exceeds a safe value.

How to Protect Loudspeakers from Over Current Surge
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.
