Cornwall 1 crossovers

I have a pair of Cornwall’s I’s purchased 10 years ago from the original owner. They sound great. They had the original caps which I replaced thru Crites. I also replaced the stock tweeters with Crites CT 125. While I’m happy, and not obsessed with improvements, I do wonder about the stock crossover’s. Any advice on upgrades that would make an audible difference? Or leave well enough alone?
