I just bought FE83en and would like to use it above 500hz with a 6/db crossover on an open baffle. But to do this I need to flatten the impedience at FS. So when I plug the FS of 165hz, RE 7.5 ohms, QES 4.06 and QES 1.057 in a seriese notch calculator it calls for : 121.7 uf, 7.65 mh and a RC of 9.45 ohms. Ok but my question is can I use other values for L and C as long as they are in resonance at 165hz. For example could I use 25 uf and 37 mh and a RC of 9.45 ohms or am I stuck using that 121.7uf cap and 7.65 mh inductor.
