wheelman Posted June 27, 2017 Share Posted June 27, 2017 I was wondering if you hooked up the inductor in a heresy network from the input to the "inner" lead of the coil then the outer lead goes to the woofer terminal? I'm thinking about experimenting with inductors. Quote Link to comment Share on other sites More sharing options...
pzannucci Posted June 27, 2017 Share Posted June 27, 2017 There should only be the two leads on the inductor and there is no polarity with an inductor so you can hook it up either way. Sounds like a read up on how inductors work and their application in a filter network is in order. 1 Quote Link to comment Share on other sites More sharing options...

muel Posted June 28, 2017 Share Posted June 28, 2017 I've heard that there can be a slight advantage for RF rejection with foil caps if you connect the outer foil to the low impedance side of the circuit. The outer foil gives you some shielding. In our crossovers it should be towards the input side. Might not make a "dimes worth of difference" but that is no trouble at all and doesn't cost me a penny. I certainly don't know much at all about inductors other than its a way to make a magnet. If you held an inductor to an oscilliscope probe on one end and ground on the other and compared with it connected opposite ways would you see any difference? (I'm probably showing my ignorance.. if my question doesn't make sense) 1 Quote Link to comment Share on other sites More sharing options...

djk Posted June 29, 2017 Share Posted June 29, 2017 Years ago I needed to mount an air-core inductor on a speaker magnet. I really didn't want to, but space dictated this choice. I got out my trusty LCR meter (that had ESR), and measured it both ways. No measurable difference (I would still have not done it if I had a better choice). Coupling between inductors is something to worry about, if you have the room. 1 Quote Link to comment Share on other sites More sharing options...
wheelman Posted June 30, 2017 Author Share Posted June 30, 2017 Thanks everyone there is only one inductor in "C" network. I haven't got it out of my speaker, but from what I remember the wires seem like they came with it? I wonder if I can change them out, or if they are under specific layers or foils I may screw up. Its the stock one in the Crites crossover I have. I would like to test different wire to it before trying new inductors. Just to see. Drives me nuts having those two wires different.
