Congrats on your Klipschorn purchase , I bought a new set in 86 for stereo and they are now part of a home theater system. I agree with Soundbound Paul Klipsch did a fine job with the Klipschorn. If you have some bad caps , then change them out , my personal opinion is to stick with factory crossovers and horns , some want you to believe that they need to be modified , I don’t think so , they sound fantastic as built . I listened to a pair of supposedly upgraded Klipschorns and wasn’t impressed , I think they were downgraded, but everyone hears differently I suppose . Don’t listen to the naysayers, you’ve got some awesome speakers.
