It looks like a stray probing finger pushed in the center dome of a midrange driver on one of my speakers in my back-up system. It doesn't seem to effect the sound quality but is unsightly. Has anyone had any success in pulling out the dimple without replacing the driver?
Thanks all! The vacuum didn’t work. The dust cap on my driver is probably heavier than on most speakers and is constructed of multiple layers of fabric. I was able to get it almost perfect with a piece of Gorilla tape as in the video supplied by akg_ca and it looks much better. I will try to remember to keep the grill covers on when not in use.
Capital my good man, capital.. I can get them almost perfect with a sharp dental pick and tape.. You only need a DUST cap to keep debris and dust out and stop the air leak from front to back. Adding a phase plug the cone to phase plug clearance need to be as close as possible without touching.. Again air leaks..
