Speaker Protection Circuit

High-quality low-frequency chain is relatively very expensive and thus no wonder that they are trying to protect its individual components in every possible way against damage or even destruction of improper manipulation or random problems. One of the possible failures are punctures one of the terminal transistors power amplifiers or any other cause, leading to
