Modifying Philharmonic 3 crossovers

Hi, everyone I'm new to modding so I'm going to need a bit of help. I have a pair of Philharmonic 3 speakers and I see that they have Claritycap PX capacitors and I'd like to  change them out with Claritycap's new CMR line up although I'm not sure how to start. I see that two of the capacitors are rated at 20uf & 250Vdc although there aren't any CMR caps that are rated at 20uf only 18 and 22uf and 400Vdc. I'd like to upgrade the capacitors although I'm not sure how I would proceed. I would very much appreciate advice on this topic. Thanks!

What is the cap used for in the circuit?

Wow, Thanks for finding the CMR 20uF model Erik, You're a life saver! I'll definitely make a note of the advice regarding the capacitor. I have a few more questions. I heard the CSA caps from claritycap sounds phenominal with bass. Would anyone say that there are better caps for bass than the Clarity CSA?

Well, I don't know about bass. In the pass through, they tend to be a little dark.

However ... as shunts in a woofer, film caps absolutely rule, and CSA caps have a very nice price point. Several modders have been impressed by how changing the woofer caps improves.
Mind you, this is a dangerous place. If you are replacing an electrolytic you really need to know the ESR and compensate for changes.

Please look at the sizes and weights though, CMR caps are effing huge and heavy! :)

Make sure to plan for that.

Based on my research, I don't believe I have any electrolytic caps in the crossover, just solen 400v PB series Polypropylene fast caps and for the mids & highs there are clarity PX series caps.
I'm not sure what you mean by "in pass through".
Hahaha, I'll definitely keep the size and weight of the CMR in mind.

Also, I see that for the mids & highs there are two caps. LOL, is it ok to mix and match brands?
