My grandson (20 months) was over and after he left I noticed a 'dimple' on one of the woofers dustcaps (metal).It's the size of ...a 20 month old's index finger tip !!! Just left of center. I usually leave the grills off but when I know he's coming over, I install them; this time I forgot! Has anyone tried to 'repair' this? Klipsch customer service people recommended using the hose of a vacuum cleaned; tried that,it didn't work. Any other ideas? Don't forget, it is a very light aluminum dust cap. I know it doesn't effect the sound, only the mind!
