I have a pair of Energy C-6 Connoisseurs that I picked up for $100. I think this was a pretty good purchase, since they blow my Kef Q-50's out of the water. But my cat destroyed the tweeter in one of them, since they have no grilles. Is it worth replacing? If so, can someone recommend a good replacement? I'd obviously be replacing both tweeters. Maybe these speakers suck, and I should just save for something better. If that's the case, my price range would be around $300-500 Any help would be appreciated.
