Modifying Philharmonic 3 crossovers

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?

Sorry Jonny,
In the first schematic of this page:

All components are in series with the drivers.


In the second, I added a coil (L2) which is in parallel with the driver.


For the tweeter and midrange, stick to the same serial caps.

Caps on a woofer tend to be very large, and in parallel, in those cases going with less expensive options makes a lot of sense.


Best,

That article was very informative Erik, thanks! Okay, so if the caps are in serial then stick with the same caps, got it. How about one type of caps for the tweeter and one type for midrange?

How about one type of caps for the tweeter and one type for midrange?

I'd recommend all series caps be the same.

Because parallel caps are not directly in line, and often much larger and more expensive, that is where you may want to do some cost savings.

What I'd recommend for instance is to use Clarity CMR for the series, and ESA or CSA caps for the parallel. 
Imagine the expense if you had gone with all Jupiter copper foil! :)

Hi Erik, I already purchased an 100uf clarity CSA capacitor to replace a Solen fast capacitor of the same farad rating for the bass. I just now ordered two 20uf clarity CMR capacitors to replace two clarity PX capacitors of the same rating for the mid. I also just now purchased a clarity CMR 3.3uf and 5.6uf capacitors to replace two clarity PX capacitors of the same rating for the highs. I was wondering about something though, there is a Solen 50uf capacitor that connects to both the two 20uf caps in serial and the 3.3/5.6 in serial. I want to replace the solen 50uf with another CMR capacitor although there aren't any 50uf CMRs. Would placing a 15/15/20uf capacitors in parallel be ok? Lol, I know, purchasing a 50uf clarity CSA would be a lot easier(and cheaper) although I'd like to keep it all CMRs, except for the bass(100uf CSA). What is your suggestion?
