Every so often, I hear vibration sounds emanating from my Totem Arro speakers during bass passages. I have determined that the vibrations are coming from the binding post panels on the back of each speaker. These panels are composed of plastic that is "riveted" to the wood. Thus, the panels are fastened by rivets, not screws, so I can't tighten them with a screwdriver. I tried to eliminate the vibration noise by lining the edges of the binding post panels with Blu Tack, but I only have one pack, which did not yield enough material to cover all the edges of one panel. At this point, I have considered buying a few more packs of Blu Tack at Home Depot or Lowe's to complete the job. Is this the best course of action or is there a better material out there that I should try? Will anything work? Thanks in advance.
