Tony,

That's what I'd suggest as well: Use the M2i's on their sides. There will be a difference in the sound, but not all that large a difference. I did comparative tests of the M22 used vertically and on its side some time ago, and it sounded surprisingly good on its side.

But the VP100 will certainly work quite well as a surround speaker.
