On many system 11 games Williams installed a resistor in series with the ground wire on the volume control. This prevents the volume from being turned down below a certain level (always too loud IMO). You need to remove that resistor and bypass it. Then you'll have full range of the volume. The Elvira manual shows the original factory wiring of the volume control and shows the value of the pot.

Quoted from kyle5574:

I don't see it in the manual, but other System 11 machines use 10k ohm.

It wasn't shown in all manuals. I know for certain the wiring schematic is in the Elvira (EATPM) manual in cabinet wiring schematic.

Quoted from jackd104:

Check for a min volume override setting in the menu and enable it.

That's for WPC games, not for System 11.
