Crossover - Polarized vs Non polarized Caps

[turnitup]

I’m working on some 60’s University speakers and need to order some new crossover caps. Normally I replace all of the caps with poly caps, but this beast has a 200uf and 250uf cap in it and I’m not going to spend $300 to replace these with polys. Both of these caps are polarized, which I haven’t run into in replacing crossover caps. Am I OK in replacing these with non polarized crossover caps? Do crossover caps even come as polarized? Probably a dumb question, but there it is. I’d sure appreciate some knowledgeable input on this one…

Nichicon ES bi-polar would be my recommendation. You can use 2 100uf in parallel for the 200uf and 2 100uf + 47uf in a parallel for the 250uf.

Since the parts are probably 20% tolerance a 220uf may work as well for both.

I've seen capacitors marked as polarized many times in old speakers. Not sure if they were really polarized or the mark means other thing. But I always replace them with non polarized caps.
