Replace ALL the capacitors in that crossover, since electrolytic capacitors basically suck. No need to use Mundorf, they are very expensive, too expensive for what you are getting. The resistors should be fine, they hardly if ever age, unless they got real hot and burned. With older tweeters, the ferrofluid usually dries up or gets thicker which is no good. An oil change would help those tweeters, they sell ferrofluid here at PartsExpress.

Thanks for all the suggestions.
I have tried multiple locations for these speakers in the listening area, bringing them out away from any side or back walls....but the highs still aren't there.
Awaiting new capacitors to arrive...only spent $50 for 2 sets of 3....i say only, because the Mundorfs were competitive priced vs Dayton's or Solen's brand of metalized polypropylene capacitors.
i will report back how and if any sound changes....then may try the fluid change on the tweeters....would be my first try at that!Comment

Update 6.30.21....All 3 capacitors replaced on each crossover board and carefully removed old ferrofluid in both tweeters. Added new ferrofluid to tweeters. Took out the pink fiberglass insulation and replace with new fiberfill.
Wired everything back together. I must say, to my ears, the sound is much brighter in the highs. I will give the caps some time to warm up and report back on further improvements.

Hope you didn't throw the fibreglass away because although horrible to work with, it's arguably the best stuffing material.Comment

There was 3 short pieces of the pink fiberglass inside each cabinet..I kept them..and what looks to be carpet padding as well...I left that in since it was stapled inside the walls and bracing.Comment

I am not sure if I mentioned previously, that these are double rear ported enclosures...make me wonder if fiberglass dust or particles can escape thru the ports?
I have read that fiberglass is a very good sound insulator vs other materials.Comment
