Hello, been an avid reader but never posted. I recently purchased a pair of KLF20 that need a little TLC. I noticed one of the mids gets a little static when I just turn it up a little. Not constant but definitely noticeable. I figured probably needs a new diaphragm but I had a K55-V laying around and decided to hook it up in it's place and I noticed the same static. This is only on one speaker, the other is fine. So could this be something with the crossover?
