Electrolytic capacitors are polarity conscious, so they can normally only be fitted one way round.

Other capacitors are bipolar, but I have heard some say they can hear differences depending which way round they are. :o

What are they, some are some aren't.

IMO never use electrolytic capacitors in crossovers even just as a protection cap as in this case.
