test crossovers or capacitors with frequency sweep

Hi everyone - I know that with an inexpensive calibrated mic (eg umik) and cheap/free software that generates a frequency sweep you can produce a frequency versus loudness curve for your speakers. If you have this curve from the factory (it came with my speakers, Celestion 700) can you examine the match between your curve and the factory one to see if of some of the crossovers have changed? Wondering if I should recap as I just bought these used, and this seems like a way you could see if there is enough of a change to matter. Thanks for your help.

thanks- my main issue is that it is really hard to get to the crossover for one of the speakers that I also want to work on (B and W 803 matrix series 2).

Thanks to you all for your advice. I will try this simply for the fun of it, as a mic is not that expensive. I guess an important conclusion from what you are saying is that capacitor changes that can be heard and matter will not make a big difference in the response curve, or will be smaller than the variance in any case. I will compare near and far from the speaker to minimize effect of the room. If I am really fired up, might take the system outside :)
