Differentiating audibly between bad caps and bad Ferro fluid


Is there any way to differentiate, audibly, between worn caps vs dried up or mucked up Ferro fluid? My JBL and other speaker tweeters ARE working, but high end informbut high end information seems off to me. Opinions? Thank you

Be careful replacing electrolytics that go to ground through a resistor as the ESR is critically important in those components.  In series with the drivers is less critical.

Well, if your speakers are old and have FF go ahead and change it.

If you have electrolytic caps that are > 10 years old replace them with modern electrolytic caps. They are inexpensive.
