DM7 recap

[Andy1]

I’m about to recap my dm 7 mk1’s. I’ve got the original crossover drawing and it doesn’t match the crossovers themselves in as much as they’ve put 1x4.7uF where there should be 2 x 1.5uF’s in parallel for the tweeter. They’ve also completely omitted a 1.0uF in the woofer side. Basically the entire crossover is full of 4.7uF’s. By the looks of it they’re all original too. I’ve found some polypropylene film capacitors on the bay (cylindrical shape unfortunately and 630v not 100v) . Questions are:
1. should I just replicate what’s there or fit to the original drawing?
2. Any better places to get matching caps from?

I can't see the circuit diagram clearly unfortunately but if they sound good as they are I wouldn't change them. I don't think those caps (polyester) age much either unlike the round (electrolytic) ones.

Why do you think the crossovers need re-capping?
