I auditioned both the FXi5 and FXi3 and ended up buying the FXi3's based on usage and wall placement. They are spectacular sounding. My friend has a full 7.1 setup of Paradigms and was anxious to hear my new setup. He wanted me to play the FXi3's by themselves. He couldn't believe the tight bass and highs from such a small speaker. The beauty is dual soft dome tweeters. They are extremely smooth, and envelope your room. I recommend wall placement since they are dipoles, mounted at ear level.
