They are indeed sharp,crisp and clear sounding, but I dont believe they handle the power Infinity claims. I am still confused about the ratings because with the supplied paperwork from Infinity, they say because of the factory wiring in cars, the speaker actually sees 4 ohms, but are otherwise rated at 2 ohms. My amp is CEA compliant at 60WRMS@4ohms and 90WRMS@2ohms. So if the Tweeters actually see 4 ohms, RMS was a close match, but if 2 ohms is really what they "see", then that explains why they are blown. Also I have last years set of 6x8's with these same MMD tweeters and you guessed it....the tweeters in those are toasted...so much for the RMS on those too. Watch your power and you should do well with these.
