I posted recently about a DQ-10 mid range speaker crackle and receive a couple of helpful responses -- thank you!? I think part of my problem was bad solder connections on the main mid range speaker terminals after I installed a new Regnar rebuilt crossover board.? It seems when I pull on the gray wire on the right side of this speaker, after resoldering the connections, (see attached photo) the crackle sound comes back, or worse, the sound completely cuts out for all five speakers within that entire speaker!!! I am far from an expert, and I think what I may have done is held a? hot soldering gun on this terminal for too long and the solder joint inside the speaker cover has come loose.? So, I tried to remove the magnet cover (three screws) from this speaker to see if I could just resolder the inside part (where the tensils connect?) and I cannot get this housing off!? Anyone ever do this?? Did I kill this speaker? Is it something else?? Thanks in advance, I really need help.
