I have an Apollo arepachi which is in a Maturi frame.
Has anyone installed volume controls / potentiometers to help dampen the volume?

I noticed the sound runs from the top boards of the machine immediately to the front panel speakers, but unsure how easy it is to open that up so before I tear it to pieces (I've only gone so far as removing all the glass panes) I'm curious what other people have done for this style of machine.
