I don’t have much doubt. Though the Stereophile measurements show a bump around 1800Hz:https://www.stereophile.com/content/kef-reference-5-loudspeaker-measurements
The issue is the formula liking narrow directivity, with the Reference 5 is, so with real human trials it likely wouldn’t score as high as the formula predicts.
It seems odd that the formula favors narrow directivity. The listening tests heavily favored wide directivity, so much so that Toole lists wide dispersion as the second most important metric after flat LW.
