I have the Bose VCS-10 for my center channel and I am starting to think it has a flat sound. When I demo equipment and home theater stores, there center channel always seems to be for full and alive. Is it the fact that I don't have any external amp and that the center speaker is running off of receiver power (receiver is the JVC RX-6000, 100 Watts x5)? Or, is the Bose VCS-10 just not a very good performing center speaker? Any recommendations to get full, alive sound out of the center speaker, since that is where most of the action occurs?
