That is the time that will take for the speaker to be disconnected after the DC threshold voltage has been detected.
Reducing its value will reduce that time delay.

If an amp gets a high DC voltage on its output, how long would it take to cut the speaker off?
2.5 second, too?

A large DC will speed up the charging time for Ci through R1,2.
But not that of R5/C1.
If you want fast cutoff, the easiest way is to reduce C1.
You don't want to change Ci because you need it for AC filtering.

We recommend that you use a 10M resistor or smaller value for Rrs.
10M will give the longest reset time while still sufficient to compensate for any leakage current of OP1.
But you can also use anything between 1M and 10M.
You will still get reasonable reset time, sufficient for you to switch off the amplifier for fault investigation.
