The left side of my paragon has periodic distortion in the 375. I recognize it as a contact problem which is easy to correct with cleaner and some de-oxit. Problem is I hate removing the red JBL seals if the contact is inside the back of the driver. I'm hoping it is somewhere between the LX5 and the driver or perhaps the switch in the LX5. I know my LE-85s in my other speakers all have foam pads that have long since turned to goo but I have resisted opening them to change out the pad. I seem to recall that the 375s had a felt pad that would not decay another reason not to open them unless you have to. I know the collector value is diminished when the seals are not intact but any alnico LE85 with seals will always have a bad foam pad by today. My question, finally, is how often do you folks have this intermittent problem in the connections inside the compression drivers? Anyone have an LX5 switch problem?
