Roy's designs are about function and sound quality. I have heard some beautiful looking speakers that sound terrible and they had great gear in front of them. The Callisto is so good, I have owned them since their debut at RMAF. Roy has told me the EOS is better than the Callisto, but if I am moving up, it will be the EOS III. Why compromise? Roy's dealer network is expanding and he has several dealer orders to fill first. Setting up a new line to manufacture is costly and time consuming. I can wait, since I know the end result is worth waiting for.
The tweeter is by itself since it sounds best with air around it. Minimal cabinet deflections and fantastic adjustability. Worrying about it breaking off is absurb. Roy builds like a tank and has the best warranty in the business.
Time will answer the questions we all have on the sound. It will not be everyones cup of tea, but it is about the music.
Enjoy!
