I have the UERM and the internals look very simple. It seems to be two of same high and mid drivers with a bass driver, which is likely a CI22955, and both high and mid drivers goes into one tube. Both all 3 drivers uses white filters. There are 3 components in there, which looks like 2 capacitors and a resistor/diode. Need to look closer for the connections however.
Also, I want to ask what is the center tab for?
Edit: Are there more information about the phases of the drivers?
