Sherpa, the YG is an awesome center channel, voices are clear and articulate - the best I have heard.
I did order it as a center channel. It is the top module of an ANAT II. Instead of having the mounting hardware on the bottom, it has holes for feet on one side. I don't use the feet as I have it on the top of a Sistrum rack. Other than that, I don't believe there is anything different about it.
