I was using a different chart

Posted by Ralph on June 5, 2012 at 13:49:13:

This is what Dr. West sent me late last year, which is probably a lot more recent.

The one with the peak is with no resistor if I have his notes right. Sorry for the bad resolution but this is how I got it. So I have base a lot of my conjecture on this chart, but it is quite clear that it probably does not represent all speakers- probably just the newer ones. That peak though being up to 40 ohms says to me that the cap can be about 1/4-1/3 of its original value in those models after the resistor is removed.
