When you look at some pretty nice crossovers by some good manufacturers like JM LAb/Focal you see that they use a nice quality series caps but the parallel caps are much lower grade electrolytic. So why does everyone here seem to recommend high(er) dollar caps all around? Just a question. I am not disagreeing.

    Series caps have a much greater influence on sound. For parallel caps in the LF section I still use film caps, but not always of the same quality as series caps in the tweeter circuit.

    There are also a few other factors. Sometimes very large values are needed in the LF circuit, so electrolytics are used because they are much smaller and much cheaper.

    For example:
