When you take out the 10uf, you are raising the HP filter to a higher frequency. The reason its moving is it may be too low of a frequency in the first place, or just loose.

I checked my foam pad where the ribbon bends back (about a 9 inched below upper ribbon anchor point on my DS) and it was completely gone. I put in a new peice of foam and it tensioned (took up slack) the ribbon just enough that it now does not move as much...

All good points....
But its the caps an coils...Look the Caps are +- 10% hell thay could be at 20years of hard driving diff amps.. 100-120mf now.....An Any coils make movment when there gluded down... EZE to see this... an the should be nothing in the middel of the coils ...there best sound is when there just freeair!
Too low crossover point.. is what i am saying....there should be NO movement for the Best sound....with any tweeter... even if it just hanging... the Stage has nothing No foam... it just hangs...
For years this has been the BIg downd sides For me ...With Magnepans..
There so called True Ribbons Move all over the place....
An i have even seen some say this was good for the brain dose not work that way....i dont read moveing the book..
So any movement is out for the best sound....FOR ME!
But like i said.... Most well not do the work!

One more way to get better sound with Apogees it too just let the covers hang...puting in the bottem swes in can unaline the Drivers.....
this give better bass an highs...better sound all around that all i wont!

An Yes when your driveing hard with a good Amp.... The Apogee or any other Ribbon Mid-tweeter....An it get so Hot you can just tuch it or hot at all....
The crossover point is to low...Or you got a Amp that can keep up!
An Guess what the Apogees are all over 20years old if thay still work now an you fix this...get a nother 20years an Better sound...not bad for just pulling a cap an moveing some coils around!......Have fun live long have good sound
