" On the other hand, if the panels are tilted back, then the bottom of the ribbon may be 6 -8 inches closer to one's ear than the top, and each point from top to bottom is a different distance from one's ear. This arrangement gives the maximum time discrepancy possible."
I was thinking pretty much the same thing with regards to the bottom of the ribbon moving toward the listener and the top moving away. I'm just questioning the why of it. How do you know its a time coherence issue, and not a roll off/freq. response issue? Magnepans do measure poorly in that area. I don't know for sure, so you may very well right. I know freq. response can be measured. Is it possible to measure time coherence?
