" I took it upon my self to fix them, and that eventually turned into overhauling the entire speakers. I re-coned the drivers and and radiators, but the sound wasn't quiet up to spec - so I bought the stuff new from Klipsch. I sold the old drivers on ebay but still have the original re-coned passive radiators (I'll throw these in as well - they look new and go for about $125 new from Klipsch). Here is what I updated: -2x New 12" replacement speakers from Klipsch. These are not the same speaker, they are upgraded models with paper surrounds. -2x New 15" replacement rear passive radiators Klipsch. These are not the same radiator, they are upgraded models with rubber surrounds. -2x New horn diaphragms from Klipsch -2x New titanium tweeters from Bob Crites - way smoother than the Klipsch ones. -2x All new caps from Bob Crites - Way better performance than original, real smooth. All of this stuffed was sourced new from either directly from Klipsch or Bob Crites. The rest is original. All the parts, including the new Klipsch drivers, perform better than originals. These speakers are matched perfectly. And they are still breaking in. I did all the work myself, including the crossover stuff. I am a hobby electronic guys and build amps crossovers, etc... For the Bob Crites crossover upgrades I still retained the original binding plates and transformers from Klipsch. These speakers are good for the next twenty years at regular day use."
