Is there a way to limit the maximum volume of home stereo speakers?
If you run a resistor in series with the speaker, it will reduce the sound output, and the resistor will generate heat. However, this could become a fire hazard. Home stereo speakers are generally 8 ohm, so a resistor in series would require more power, which depending on the size of the resistor, the amplifier would ultimately be unable to deliver a lot of sound. You could also replace the stereo receiver’s fuse with a low amp fuse so that when she cranks it up, the fuse blows, disabling it completely. Or you could coat the cones of the speaker with some sound-deadening material such as white glue or rubber cement, but this would degrade the sound quality severely.
