I would also suggest that, if there are indeed NP electrolytics in the XO (a fairly likely situation), that you consider replacing them with with film capacitors. They don't have to be expensive boutique types; the inexpensive "Dayton" brand from PartsExpress (which I believe are rebranded Bennic capacitors) are good and will, IME & IMO, audibly improve the performance of most any old-ish, consumer-brand loudspeaker.
This being said, there are probably good reasons not to just revise a crossover willy-nilly, and even a lowly NP electrolytic made today is almost certainly of better intrinsic quality than the original capacitors of 30, 40, or more years ago. Plus -- electrolytics do age... and not gracefully.
So... yeah, were they mine, and were I disposed in spending a little money on 'em; I'd give serious consideration to "recapping" (as they say).
Applying those same rubrics (i.e., my speakers, my money), I wouldn't bother with the other "passives" in the XOs (resistors, inductors -- if any).
Just my opinions, of course -- and way more words than the subject really needed. Sorry!
all the best,
