The mini's I audtioned weren't optimally placed for sure. The woofer was off to the left of my knee.. the two main panels were correctly spaced, but had a lot more room behind them then I would in my room/setup.
The movement of one instrument as it dropped in frequency from a center position to the left of my knee was quite audible to me and rather disconcerting. I question how well a system can work with that high a crossover point. You're well above the range where the ear supposedly (I believe there is a lot of debate on the subject) becomes non-directional.
Having instruments move from the desktop to down around my feet might be just as troubling.
I Googled "low frequency directionality" - and found this in a Wikipedia article:
Evaluation for low frequencies
"For frequencies below 800 Hz, the dimensions of the head (ear distance 21.5 cm, corresponding to an interaural time delay of 625 µs), are smaller than the half wavelength of the sound waves. So the auditory system can determine phase delays between both ears without confusion. Interaural level differences are very low in this frequency range, especially below about 200 Hz, so a precise evaluation of the input direction is nearly impossible on the basis of level differences alone. As the frequency drops below 80 Hz it becomes difficult or impossible to use either time difference or level difference to determine a sound's lateral source, because the phase difference between the ears becomes too small for a directional evaluation."

Another interesting discussion on low frequency localization:

I've given thought to getting the MMGs with the return option and seeing if they can be made to work correctly - if not send them back, and think more about the MiniMagi, or?
