[QUOTE="ludo, post: 83788, member: 691"] Doogle, if you have the x-overs out again, do replace those caps. They look like polarised types to me ??? and very long in the tooth. If you replace with a plastic film type (polyester is not expensive) they'll last forever. You might have to add a good couple in parallel to get to the right value for each cap. Up to 2.2 microfarad (100V or more) should be readily available from places like Communica/Yebo etc. Ideally one would reconsider the values of x-over components when replacing drivers, but what's in there now might work well enough. My concern is just that if crossover components fail, they sometimes take the driving amplifier with them. Open- or short-circuits can create some very unreasonable demands on amps so it's better to play it safe. Age usually improves people, but never electrolytic caps. [/QUOTE]
