The only significant drawback I found was in the center channel. As I moved around the room I noticed fairly significant lobing which reduced movie dialogue intelligibility to the sides of my viewing space. In addition, I noticed a slight chestiness or nasal quality to male dialogue in movies, the deeper the voice the more pronounced the problem, especially when the characters were not speaking with significant volume (turning the volume up usually compensated for this problem).
I also noticed that the center channel was not a perfect timberal match during movie scenes in which sounds pan from left to center to right. I also had the center placed on top of my TV about 2 feet above my head while seated and I feel this contributed to the audibility problems I had with movie dialogue. On the â€œknockingâ€ test it becomes immediately apparent that the center channel has a good deal more cabinet resonance than either the towers or the monitors. This single factor could be responsible for almost all of the inconsistencies I found between the center and the rest of the system (and might be an easy fix for version II). In their defense, all surround setups will exhibit some degree of inconsistency between the L/C/R unless they are identical. One bit of advice I have for users is to play with the center channel placement. If you can put it directly on ear level or slightly above that would be ideal but definitely try to keep it within 12 inches above or below your seated position (and at least 2 feet off the floor).
