I have a number of these in my room. Without question they have improved the overall sonics and naturalness of the room's acoustic without the dampening, dullness, bass-suckout or frequency imbalance I have experienced with other products. Even speaking within the room as you walk in, sounds natural. There are no reverberation or unnatural colorations apparent. It is a pleasant room in which to listen to music, talk with friends, family or when converted to a movie theater, it becomes exceptional, without the sharp-edge to loud movie sound passages. The Stillpoints and the room build are what I consider to be the key system strength.
