Only if you regularly host large viewing parties where people are spread out across the room.I'd considered the HC1 but from other research I've done it seems like a 3-way is going to be a large improvement over a 2-way MTM design,
If it's just you and one other person sitting in front of the center speaker, a well designed and properly positioned 2 way can work very well.
That said, all the worst center speakers (Pioneer C22, Polk CS2/8//10/20, etc.) are 2-way designs so that's why I tend to recommend 3 way horizontal centers if I'm not sure about the exact make/model available to folks esp. those living outside of North America. Have yet to hear of any truly BAD 3-way horizontal center, but that could because most retail speaker companies only offer 3 way centers only in their top shelf model lines (so that they can price gouge the daylights out of you).
