Measure what you have. Don't just mirror.

Why are my crossovers different
You can use Room EQ Wizard, or DATS to measure your caps with high accuracy and the correct ESR. https://www.roomeqwizard.com/help/help_en-GB/html/impedancemeasurement.html https://www.parts-express.com/dayton-audio-dats-v2-computer-based-audio-component-test-system--390-8... Also some handheld meters I know nothing about. Best, E |
Ditto on measuring. I would take the group of 4 caps you removed from each board and measure their capacitance in parallel and that is the value I would use for the new ones. The design value may 26.7 but chances are the manufacturer tested every driver and tweaked the caps to allow for variations in driver paramenters to meet overall design specs. (If one of the four caps is much smaller in physical dimension than the others, then that is almost certain what they did). Without measuring the original caps, your best bet is to install 26.7uF total. |
I looked at my buddy's pair and his are 26.3, two 10uf, a 4.7 and a 1.5. Here's the question... can they be measured on the board. I have taken this crossover apart a million times and I'm not going to desolder the finished crossover to measure each cap. So the question is do I put it back at what was original with the 28uf, or do I get it close to the other side 25.7. Or just get it as close to the 26.7, which if I leave the 6.8 in there and leave the 1uf out. I'd have 26.8 |
