I had a pair of older maggies...before they went to the ribbon tweeter. I suppose that could make a difference, espec if the Maggie ribbons are wired out of phase.

Follow Ups:
I had sorta assumed they WOULD be polarity-coherent and it really surprised me that they weren't. You may well be right about the older ones.
Ever play a sine wave through a Maggie with the grill cloth removed? The panel does NOT move in a push pull movement. Instead it generates a series of waves, similar to whipping one end of a long string: you will see a waveform moving down the length of the panel. It is very different from an Apogee or ET planar magnetic.

That makes two of us.Thinking about it further, it may also have to do with how the Maggies are positioned. It's possible that the backwave either reinforces or fights or mixes somewhere inbetween, and this may affect the ability to perceive a polarity change.
