The VP100/150 and M2/M22 all use the same drivers thus have virtually perfect timber match. If you can't fit the shorter M2 as a center then either of the VP series you are looking at works very well.

I have been using my VP100 instead of my VP150 recently and I think I might prefer it over the 150 even though the 150 plays most male voices better, some seem to have a resonance to them that is not quite natural on the 150, IMO, but this could also be seating and room issues. I need to do more listening but I am sure you would be happy with either one of the VP series. smile
