Optimizing any two of room, subwoofer, and seating yields the third

Evidence

The approach offered by Allison (1974, 1975) and Ballagh (1983) involves choosing the position of the loudspeaker with respect to the boundaries in a manner that minimizes the variations in frequency response at the listening locations. Obviously, the goal is to arrange for the woofer-to-boundary distances, floor and walls, to be as different as possible, while not being multiples of each other. The more different these distances are, the less will be the effect. Finding an optimum result may involve some trial-and-error in practical listening. It may also result in visually unappealing, asymmetrical, or incorrect (in terms of stereo or multichannel imaging) locations for the loudspeakers. — , Toole, Floyd E - Sound reproduction-…, 1068 (#expands, via linked claim)
