[When to replace crossover capacitors?]

Unfortunately I am physically not able to disassemble the speakers and access the crossovers to test the caps, so wanted to know if there's a non-invasive way to assess the caps before I hire someone to take the crossovers out to send them out for capacitor replacement.

 

Hence my questions:

1. Have 40 year old caps most likely degraded to the point that replacement would make audible improvements?

2. Is there a listening test to determine if capacitor replacement would improve sound?

[When to replace crossover capacitors?]

How do I know if I need to replace the capacitors on ~40 year old Klipsch Chorus I's? The speakers are new to me and sound very good, but lack a certain "crispness", and I want to know that I'm getting the most out of them.  Does one assume the speaker age alone merits replacing the capacitors, or is there some listening test or test \ tones I can use to determine the need for replacement?
