Magnepan, Ohm, Spatial or ??

I've heard the mag 1.7s and like the "openness" and other attributes.  However, the size and placement requirements are a killer for me.   I'm thinking Ohm and Spatial would be somewhat similar.  However, I can't demo them.  Any thoughts on these compared to the mags and any other "open" speakers I should consider?

Thanks all as usual!!
