wonder dynamicaps any good ?

hi, i have a pair of infinity kappa 9's and a couple of the solen caps went bad in both speakers, one emit and on the other speaker on a semit, i bought 8 new solen caps for all 6 tweeters but to me they sound kinda harsh, so i was just wondering if anyone has tried using the wonder dynamicaps as i have heard that they are pretty good sounding, if so how do you think they would sound in the kappa 9's being that they have ribbon tweeters, will there be any improvement over the solens?, if so what can i expect, thanks in advance.
