Setting the DC protection on K4700

Hi, have a question regarding the K4700 speaker protection circuit

The current design is to limit the voltage offset to 1V. I am thinking that to be safer, would want to limit down to maybe 200-500mV.

Any advice on what parts to change to effect this?
Thanks

1V is not a problem for most speakers.
Setting it too sensitive can cause unintended activation of the circuit.
Anyway, decreasing R21 & R22 can help. Sorry, no values, please experiment.
