That depends on how you define a "room". <G>

Seriously, when I had my 'media room' built, I left one wall open, 
interrupted by a fireplace between the new space and the old. Yes, there 
are standing waves in spite of that (and despite a sloping ceiling), but 
they are not nearly as strong as they would be in a closed box.

It helps that two walls are LPs and LDs, that the primary listening area 
is about a third of the way from the rear wall, and other factors. The 
point is that if you have control of such matters, you can time most of 
the standing waves most of the time.
