The non-polarized (NP) caps that are used in speaker crossovers are NP,
but they appear to be electrolytics. Are they actually electrolytics,
and if so, how do they make them non-polarized compared to standard
electrolytic caps?

Also, what is the reason they are NP, rather than use regular polarized
caps?

Depends what you paid for it - audiophools would go into shock at the
thought of NP electrolytics in speaker crossovers.

Anything decent will have some kind of metalised film caps - and you don't
necessarily have to pay audiophool prices to get it.
