Room size and shape do not change multiple-loudspeaker sound quality ratings

Evidence

Of course, different programs will elicit different responses based on spectral interactions, and their abilities to reveal resonance or other problems in the loudspeakers. But radically changing the room size and shape had no significant effect on the loudspeaker sound quality ratings. This is profound. But keep in mind that this is a multiple-loudspeaker evaluation exercise, not at-home recreational listening, or single-stimulus subjective reviewing. It demonstrates the power of the method in revealing aspects of sound quality. — Toole, Floyd E, Sound reproduction- the acoustics and…, 553

• QUESTION: Does this result hold outside the controlled multi-loudspeaker method — or does room adaptation in real listening change ratings? The caveat is stated but the boundary is worth chasing.
