Hi all
I built crossover using high grade audiofiler capacitor having 3% tolerance. I built one first then built 2nd one after two months.
I noticed different level of high frequency from both speaker. Could not find out reason. I interchanged all components one by one including drivers. Finally noticed that capacitor causing this small difference.
I thought, due to different burning time this issue is coming. Same Time also did below DYI jugad;
A: Warming using heir dryer for few minutes - One of my friend worked in aerospace. They use to keep components in ove- controlled-warming for couple of days to get the results same as used components. Inspiration from there
This reduced difference from both speakers
B: Changed polarity (not logical as cap are bipolar) - To my surprise this also reduced the difference further
Would like to hear from experts -
1. Are there more ways to stabilise components.
2. Point B above: also experienced by someone?
