A previous discussion included a statement about crossover components.
The commentator stated something to the effect that some very high end speakers really cheaped out on the capacitors and resistors in their crossovers, and hinted that replacing them with high quality components might improve the sound quality of the speakers. My question is "Have you ever replaced the caps and resistors in your speakers crossovers, and to your ears did that result in better sound quality?" Also, what brands of caps and resistors do you consider to be "the best", and why?
@knotscott Spatial M4 Holograms. Just got my Precision Fidelity M7-A back together and am looking forward to a test drive. The Spatials are sensitive 93 db at 4 ohms so they should be a good match. Spatial offered a crossover upgrade when I bought them, but I had to pass on that.Now I might consider replacing some of the components. Since the M4 is no longer in production, I assume the crossover upgrade is no longer available also. It might be fun! |
It couldn’t hurt to ask them if the upgrade is still available, or at least what they’d recommend. Otherwise, go your own way...it should still be an upgrade from cheap electrolytics, sand cast resistors, and iron core inductors. Should definitely be fun to do if you’ve got that gene! Good luck! Don't recommend adding polyfil to open baffle speakers! 😁

Here is a photo of the crossover components on a $83K/pr speaker. https://photos.app.goo.gl/ieh8b6wj4ykdZWxF9 Here is a pair of crossovers I made for my speakers: https://photos.app.goo.gl/Gcs1i3H7gJbQtfxq9 As you can see I use a lot of Mundorf caps (I read with interest Erik’s comments). I also added a couple of Duelund bypass caps. I also use Jantzen foil inductors and path resistors. The sound is clearer, cleaner, and more accurate. Jerry |
@carlsbad2 So, your first picture demonstrates the parts for a very (to me) expensive speakers, and the second picture is crossovers for a set of your speakers, not replacements for the high dollar speakers? |
