Why should I go with an M2 when I can get a true center channel like the VP100? Its bigger than my current EC-1 but should still fit on the table I have below the TV.

The QS10's look nice. And the site shows a photo of them hanging on the back wall. Which is where my current EC-3 are. But these seem also too big for my room. QS8 may be the better choice. Never-the-less, wouldnt the design of these surrounds lend themselves to placement either back wall or side wall due to the fact that they are not one directional? Sound comes from all 4 sides of the speaker?
