Ok so i have some LX3-1 crossovers. They are paired with Le10 and Le30 drivers. Im wondering what i should do to bring the Crossovers up to snuff i guess. Every now and then i hear crackling out of the high end that seams to go away if i adjust the crossover. It seams like a dirty pot but i dont want to do anything to them without posting here first. My goal is to keep this system as original as possible. But not at the expense of quality sound.
I would like to know what maintenance should be done to these ageing crossovers? Any help is greatly appreciated.
