Magnepan 3.7's versus 20.1's?

Before we digress, I suggest

Magnepan 3.7's versus 20.1's versus Tympani IVa's

please.

I would think the 3.7s will be a distant third to both.

I have owned Magneplanars on and off since I was in high school in 1979.

They are wonderful, but need power and are extremely sensitive to room placement.

So a well set up 1.7 might also outperform the 20's. Indeed, a well set up MMG might outperform the 20's in certain situations, neither of which says anything about the value of 3.7s.

Is the "front wall" the long or short wall? This will make a significant difference if you are able to experiment....
