@KEW - How did the Canton Ceramic, RAAL, and Focal Be sound to your ears? Did you have a favorite?\nBTW what are you using for speakers now that you loaned out all of these? :D\n\nA lot of the sound of these tweeters is determined by other things like mostly the crossover and to a lesser extent the enclosure. I would be very hesitant to say that tweeter A is better than tweeter B merely from their implementation in some speaker. The overall design will have more to do with the sound even within the tweeter's bandwidth.
