So I just found my right side KG 3.2 speaker sounds boomy and has no highs. I thought that's the 15+ year-old speaker wires, so I switched the left/right channels but with no luck. HOWEVER, when I put the banana plug into the binding post, the tweeter somehow worked for like 5 seconds and then again, boomy sound. I changed a contacting point on the binding post, then, about 5 seconds of clear sound, and then back to boomy sound. I already have some new 12AWG wire and banana plugs on order, but what seems to be the real problem? Do I need to replace the right tweeter? Thanks a lot, TP
