Please look at the sizes and weights though, CMR caps are effing huge and heavy! :)
Make sure to plan for that.

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!

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: https://speakermakersjourney.blogspot.com/2016/02/crossover-basics.html 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, E |
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! :) |
