AR11--dented dustcaps--fixable?

[rogerfederer]

so most of these look like they could be fixed with the bent needle trick. (i've given up on duct tape and vacuum cleaners; ruined a 2ax tweeter that way.)

the dented mid-range looks more problematic. any thoughts?

I pulled a dent out of a paper dome tweeter by SLIGHTY moistening it with a damp sponge and applying suction from a little pump connected to a suction cup roughly the same size hemisphere as the dome. I also drilled a 1/8" hole in the cup to make sure there was a leak. It worked perfectly.

not a big deal on the woofers, they aren't original AR woofers....

the originals are slightly smaller than a true 12" and have truncated frames

I am a newbie here, but I want to point my method I have used to to pull the dents out of speaker dust cone covers using a portable hand held vacuum. I turn the vacuum on, and open the suction adjustment on the side of the nozzle full open, to where there is no suction. I then bring the nozzle to within 1/2" to 1" of the dust and ever so slowly start to close the suction adjustment until to dent in the cone pops out. I have yet to ruin one this way.

If this method is already used here, I apologize. I'm just trying to share.
