RE: It is official it is the panel

Take a flashlight and shine it through the spandex as you examine every rectangle in the speaker frame, looking for holes or tears in the diaphragm. Typically they occur at the edges, where the frame impinges on the mylar. Typically you will find them along the topmost row of rectangles, nearest the top edge of the frame. If one or two are "holey", you can repair that by "killing" that rectangle, using silicon caulk. You will have to slice an opening in the spandex so as to admit the nozzle of the silicon caulk tube. (I did it at the rear so the damage to the spandex is not seen from in front.) Then squeeze the tube so silicon caulk is deposited between the mylar and the stator. This will eventually cut off the capacity of that rectangle to respond to audio signal. It's actually a permanent fix, unless or until too many of the rectangles are affected. You won't hear any difference between the affected panel and the intact one (after repair). if it's only one or two or three rectangles flapping.
