So I opened up the speaker and it appears as if a nut is holding the binding post in place. Doesn't appear as if I need to solder anything. However, there is some purple goop (most likely glue I presume) at the interface between the bolt and the red spade connector from the speaker. What is the purpose of the glue/goop? Thanks again for everyones suggestions.
