I can easily go with a 100 uF and a 75 uF but is it better to use two caps that are closer in capacitance rather than two that are further apart or does it not make much difference either way? Aug 22, 2011 · If you have a little change lying around, and if the series capacitor(s) in the tweeter circuit are NPE's, you might replace it (them) with a decent poly cap like the Jantzens. After spending about 40 or 50 bucks on parts and a couple of hours removing the drivers, swapping out capacitors, re-glueing them in place, and putting everything back together, they sounded the same. Our Audiophiler capacitors are rated at a maximum of 400 volts, which offers significant margin over typical voltages found in audio speaker circuits. I wonder if there is any guide or listing of the parts needed for each model crossover, and recommended brand/source. A small, high quality bypass capacitor in parallel with the main capacitor can significantly improve performance. Experiment with the resistor value. Capacitor Replacement. As for the woofer, you need to determine if the driver is bad or if the wiring is messed up. 5uf capacitor (which I can't find), which is the recommended solution? 1. Boochie would then be misdirecting me because obviously others are replacing capacitors on these crossovers so there must be something they are replacing. Jan 31, 2022 · Not a technical guy but all I want is to replace the capacitors on the crossover of my FOCAL 726s Speakers . Get some decent film caps, but ones with at least 150volt rating. So if a capacitor upgrade is carried out, we can assume that the capacities will (at least) deviate on average by 2-5% from the originally installed capacitor. Over time, capacitors can degrade, affecting sound quality. The manufacturer may have balanced the crossover with the particular characteristic of electrolytics in mind. Nov 1, 2017 · I want to replace these caps with modern audio quality caps. 2 uf, and that shouldn't cause you much financial grief. Try the same experiment with a 200 volt capacitor of the same construction type, it won't make a sound.
