[QUOTE="Riley Casey, post: 218042, member: 125"] I suspect you're really over thinking this. Without knowing how the components currently perform you don't have a starting place for designing a passive crossover network. You need to measure the speakers acoustic output using software like REW or OSM. Model the desired acoustic performance with an active crossover, ideally a DSP based crossover where you can choose characteristics easily and only then start to chose passive network values and details like Zobel networks. The Z network itself is to adjust the apparent impedance of a driver to make the passive crossover network work as desired. Have you measured the impedance of any of the drivers? I gather this is a bit of entertaining DIY as much or more than an effort to get some usable live music speakers so go the extra mile to do it effectively. [/QUOTE]
