Not sure about the current conventional wisdom. I generally stack them vertically to get the mid-high driver on the upper cabinet up higher and have sometimes stacked them horizontally (usually when we're in a smaller place and an owner or manager seems to be concerned about volume - they look smaller and presumably less imposing when horizontal
).
I remember seeing the flipped configuration with fEarful and fEarless cabs in the past. But my recollection is that Greenboy would optionally build one as the top cabinet in a flipped configuration so that they could be stacked as you described.
This is complete naivete on my part but, since the only stupid question is the one that doesn't get asked, I'll ask. Is there any risk of damage to a cabinet by placing it upside down? Like I said, I never thought about it before and have no idea if doing that can have any bad consequences. Maybe @alexclaber could chime in on that one?
