...don't you think I should not use them as they are mainly for PA drivers?
As I have not used these xover's cannot comment on their quality, jaudere will be the person to ask.
Also, in all the xovers, both the coils are sitting side by side and as a result they will always keep on talking to each other cause of the Polarity factor. Don't you think that a bad factor as far as home Audio quality is concern?
I did not find more than one inductor in both the xover's mentioned (C-650SW and C-300/200).
