As a long-time dipole user, and completely understanding your interest in the Magnepan speakers (I own a pair), my advice is to forget about it for use in your current space. Why? is the obvious question.
The common wisdom is that dipoles need an absolute minimum of 3’ spacing from the wall behind them. That wisdom is debatable: 5’ is more like it in the opinion of those (such as myself) who have learned the hard way that 5’ is required for the front wave and back wave of dipole loudspeakers to be heard as separate events, rather than the back wave being a smearing of the front wave.
The literature informs us (as do our brains) that 10 milliseconds is the time required for our gray matter to perceive two sounds to be heard as separate events. As sound travels at approximately 1’ per ms, with 5’ spacing the back wave of a dipole loudspeaker reaches the front wall (behind the speaker) 5 ms after being launched, reflecting off that wall and arriving back at the planar 5 ms later, where it meets (in time) the loudspeaker. 5 ms plus 5ms equals 10ms, the elapsed time thereby meeting the required 10ms spacing of acoustic events.
When dipoles are placed closer that 5' from the wall behind them, the front and rear waves meet at varying degrees of phase alignment, which creates cancellation and reinforcement at different frequencies. This phenomenon is called comb filtering: peaks and troughs in the frequency response of the loudspeaker. Not good ;-) .
