Two sub location alternatives.One room
That does not lead to any conclusion about optimum subwoofer placement for audiophiles in general.
It also may be that Earl's data are from a computer simulation rather than from measurements in a real room. That would make the data further removed from reality.
And there was no listening panel to report whether or not they could hear differences (measurements under 80Hz. were similar).
Earl did come to one conclusion that placing all subs in corners made the bass frequency response rougher than his alternative This is because corners cause maximum excitement of standing waves in rectangular rooms and this is also well known without any measurements.
Earl does not compare front-speaker - subwoofer integration differences among his two alternatives -- this is the top priority for two-channel audio, IMHO, but of course Earl's work concerns surround sound home theater, not two-channel audio.
It is also well-known that placing one sub near the ceiling and one near the floor can prevent an important floor-to-ceiling standing wave ... assuming the ceiling doesn't rattle and make the bass sound worse!
