... sound waves CANNOT bounce off empty space...
Mmm...I don't think anyone suggested that.
It's really about the "corner"...the walls/floor all connecting to form the corner, trap the sound waves there.
The point was that having the corner door open, doesn't let the LF "escape". It may help some...but the buildup is still there, and you need to find a way to put some trapping there, even if it something movable, just to suck up the LFs.
I wonder if it makes more sense to close the door, and also put some trapping there...that way there is a symmetry between the two corners...rather than leaving the door open at one corner....?
