Timbral neutrality drives 69.5 percent of sound-quality preference

Evidence

It was found that timbral quality corresponded to about 70% of the overall quality, whereas spatial reproduction corresponded to the remaining 30%. An interesting finding was that, when low-pass timbral artefacts were present, the spatial reproduction resulted in no advantage over monophonic reproduction. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 2375 (#corroborates, via linked claim)

The most important feature of these measurements is that there is no evidence of strong resonances. These would show up as repeated bumps in the family of curves because sound from resonant activity tends to radiate in all directions, whereas acoustical interference bumps and dips change with angle and are averaged out in the spatial averaged curves below the on-axis curve. This characteristic combined with a flat direct sound is the prime indicator of a timbrally neutral loudspeaker. The shape or tilt of the off-axis curves is less important than their smoothness in this respect. — Toole, Floyd E, Sound reproduction- the acoustics and…, 1933 (#expands, via linked claim)
