I'm new to this site as of tonight. I would like to find out what the information on the back of my speakers means.. I have a pair of khorns with the serial #'s 8P757 & 8P758... KB-WO.... I've been told that the WO stands for Walnut Oiled which they are..I don't know what the KB stands for, but I was told the First 8 means 1978...will someone explain this all for me.
