I had all the Caps changed in the x-overs of a 30 year old set of speakers - replaced them with Mundorf caps.
Cost $250 for both x-overs
As long as the speaker surrounds are in good shape you won't be wasting your money - I had to have my speaker surrounds replaced also.
They now sound much better than they did with the original caps
I can highly recommend Mundorf :-)
