Basically, consider all the components in the crossover to be critical except for the Zobel. When I say "critical" here, I don't mean value tolerance is small. I mean that the quality of component determines the quality of sound. Don't use electrolytics in the signal path, in other words. Don't use coils with high DC resistance. Do use polypropylene capacitors or other high quality types. Use air core coils with large guage conductors for those under 1mH, and good quality laminated steel core for larger values.
