Will I notice improvement with crossover mods?

I've finally discovered that the difference in sound between my two Hales Transcendence 5"s is due to a difference in crossover values between the two speakers. Aparently one of the speakers was at the correct values but the other speaker's crossover was off by over 10%. I've decided to repair the speakers by having both the crossovers completely redone with new caps, coils and resisters. The crossovers of both speakers will be upgraded to better parts and they will be the same correct values(evenly matched).
My question is that will I notice a big improvement with this upgrade/mod? I am having Solen foil caps replacing the old caps, Hepta- Litz coils replacing the old coils and improved resistors although I do not know exactly which ones. Opinion would be appreciated.

Thanks for all your advice. I am researching the availability of different caps through the shop where my speakers are at. I may go with the Solen parts as they are easily available but I will wait and see what the technician has to say about his availability for better parts. How are the Solen Hepta-Litz coils, Solen foil caps and their best resistors? Thanks again

So now I am waiting for the return of my speakers with Mundorf Supreme Silver/Oil caps all around, Mundorf Zero Ohm coils and MR10 non inductive metal oxide resistors. It will be interesting to hear how my Hales will sound with these moves. As they were always different sounding from each other due to one of the crossovers not being correct, I'm sure I will enjoy the sound. As well I have my Pass X250 being looked at by Pass Labs as the right and left channels sounded different from each other as well. If the speakers weren't enough I had an amp problem as well just to confuse the issue.At least all is being taken care of at the same time and I won't have to have my system down much longer than necessary. Thanks for eveyones advice as I'm sure I'll get a better loudspeaker returned than I sent out

Mundorf makes excellent components. You will hear the generic "sound" of your speaker design much better now, and clarity should be improved. Allow the coils some (break-in) time before passing judgement, however.

Seems like capacitors are a can of worms! I decided on Hovland musicaps for my MG1.6 partly because they were of smaller diameter and greater length so that they fit nicely into the crossover cavity. I am happy with them.

One way to avoid the capacitor can of worms is to use a parallel inductor instead of a series capacitor. "Look Mom, no capacitors!" I saw a comment on AA describing such a crossover, with favorable comment.

Does anyone here care to comment?
