Replacing caps on crossovers?


Has anyone tried upgrading caps on their crossovers? Curious if they experienced any issues with changing the voicing of the speakers in a negative way? Thinking the speakers might be voiced based on lower quality components.

OP:

What you should do is gain some practical experience, cheaply!

My recommendation for inexpensive experiments are Mundorf MKP and Clarity CSA caps.

Should run you about $20 for a pair of caps. Gain knowledge for yourself. If you can't hear a difference, you will learn there's nothing to gain for you.

Musichead. If the speakers are working properly there is little to gain


Hi @Mijostyn : Can you tell me how many times you’ve tried this and what parts you used to come to this conclusion?


Is this book learning, or have you actually experimented?

Because I have the latter, and I conclude you are mistaken.


Thanks,

The negative aspects happen if you willy nilly replace caps that go to ground. Especially with 1980's, 1990's or earlier speakers. You alter the ESR and the impedance makes your amps work oddly.

Series caps are usually pretty safe to change.

When / if you replace coils, keep the DCR the same.
