Still I feel using such costly parts on the poor old klipsch tweeters is a bit of a waist of funds. Replace it, use a good cap and be done. Trust me the tweeters are a very weak link and with what your spending on crossovers parts you could afford proper replacement tweeters. I disagree with money on caps is better than money spent elsewhere for if your loudspeakers where modern and of proper design changing the caps wouldnt make much diferance. Now your replacing parts that probly where out of spec since you dont have a mint stock klipsch to compare to your voicing these speaker to your own tastes room system keep this in mind. I wonder have you tested the old caps to see if they are realy out of spec? Also with loudspeakers transducer quality realy maters as does crossover, cabinet, finish, dampening etc. Its a total design if done right. I disagree with this statement [I think money on caps may be better money[spent] than on speaker wire, interconnects or anything I can think of] I would say treat your system like what it is a system not a colection of gear. Focusing on 1 aspect of a systems performance mostly leads to grief in the long term.
