Old crossover

[Tomv]

Hi,

I'm building the old x-over I have from new parts but I can't seem to understand the way capacitors are implanted: there are 2 47uf electrolytic capacitors for the mid connected together at the opposite way - to - , is that the normal way connecting electrolytic's together and this halves the value as in bipolar cap's?

That's how bipolar electrolytic capacitors are made - 2 normal electrolytics back to back (but bipolars are made in one common housing). If you examine bipolar electrolytic capacitors found e.g. in crossovers, you'll see that they are symmetrical, as opposed to regular (axial) electrolytics that typically have one lead connected to the can and one coming out of some rubber plate (or similar).
