As I start to read & learn more about xovers, the more little questions I have. When using 2 8ohm mids in a MTM configuration wired in parallel, it gives a 4ohm load. So, when I check the charts to see what value inductor & capacitor to use I would read from the 4 ohm side not the 8ohm correct? If wired in series I would use the 16ohm chart. ***Also, if the woofers are now 4ohms and the tweeter is 8 ohm, what problems am I going to run into? Do I need to put a resistor in there /some where to make it 4 ohms? I now know how to make L-R 1st and 2nd order xovers but have no idea how to do something like this. What is this Zobel thing/impenance matcher? Thanks again all.
