Band: opinion spread · Dot: weighted average
Sources split, lopsidedly and in two directions. Erin's Klippel data, the German reviewers and most owners hear a neutral, balanced speaker — less bright than the Q150, with a slightly forward midrange around 1 kHz that Erin would trim with EQ. A minority of owners hear it as dull, muted or muffled; one was driving it from a budget Sony receiver with the treble control turned all the way up, and a dealer calls it much warmer than the LS50 Meta. A smaller group hears it on the bright, forward side of neutral.
Measured
Erin's Klippel data (YouTube review) shows a bump of about +2 dB around 800 Hz–1 kHz followed by a dip of about 3 dB centred on 2 kHz, which he says makes the midrange sound forward; he suggests a −2.5 dB parametric cut there. His estimated in-room response also shows a rise of about 1.5 dB between 150 and 300 Hz — 'warm male vocals'. KEF's own anechoic data on spinorama.org deviates ±2.3 dB between 300 Hz and 5 kHz.
vs. listeners — Nothing in the data looks dull or muffled. The 'muffled' reports come with a budget receiver, desk placement or a listener used to treble-boosted speakers, and owners in those threads suggest the listeners were used to brighter sound — but the data can't confirm which setup caused them.
“Overall, neutrality is reasonable, but that 1K or so forwardness, I recommend bringing that down with EQ.”

“They always sounds slightly muffled.”
