I have owned a pair of EV Sentry 100A Studio Monitors for about 20 years. In the last 2 years both tweeters have blown. I was unable to find replacements, until I saw on the internet, that these could replace my missing tweeters. I took the chance and bought them. They did not fit the space for the missing tweeters exactly, and so there is a moon shaped space about 1/4" wide around 1/3rd the circumferance of the opening. I am not a hi-fi buff any more to be able to comment on the erits of the sound. All I can say is that the sound is fine.
