Predicting crossover behavior from mixing values? |

I am trying to finally finish up an old cabinet I started years ago. I am trying to do so with components I have on hand. I know the right thing to do is order new, correct parts but that would cause me to put the project off again so unless this causes serious problems, your help is appreciated.
I have never actually built a crossover before. This is for a single cabinet for bass guitar. The low-end is an old Swan305 and the high is an MCM aluminum 5.25". I have several old crossovers to use as pieces. Of course none of them fit the crossover I want to build. I do have an old car audio low-pass which is just a large coil. It would equal 6db/oct @ 200hz. That part was easy. For a second order butterworth high pass I start comparing what I have. I find that I have a 6.8mH coil that could be used for a 265Hz crossover or a 66mFd cap which would contribute to a 210Hz crossover. However I have no idea how these would interact. All calculators and equations figure values based on response you want. If I build a crossover with these two pieces will it have the 210Hz knee but a different slope? Will it skew the cross point between the two values? I know either way there would be a gap in response and phase issues but it is a musical instrument speaker, not a loudspeaker. I know it's not going to burn the house down but I also don't have the test equipment to check and see the results.
