I asked my self the same question long time ago (about 17 years ago) when I read somewhere that the crossover of my 1891 HBR is only good for 20 years or so. The majority response I got was “trust your ears.” If it sounds good to you, leave it alone. I did.
Either I got lucky on the crossover or I’m deaf.
