Short answer: the KEF Q6 Meta. It ranks #31 of 98 center channel speakers by sound quality, rated 3.9/5, at $849.99. The ELAC Uni-Fi Reference UCR52 ranks #86, rated 3.3/5, at $799, $50.99 cheaper, a saving that is not big enough to make up the sound-quality gap.
The KEF Q6 Meta is the better-sounding choice. A true three-way center with a Uni-Q coaxial driver (0.75” vented aluminium tweeter with MAT inside a 4” midrange) between two 6.5” bass drivers, replacing the two-way Q650c at about the same price. The tradeoff: The only measurements are KEF’s own, and spinorama.org computes no preference score for them, so the ranking is an estimate.
What the ELAC Uni-Fi Reference UCR52 does well: A three-way center with a 1” soft dome tweeter mounted concentrically in a 4” aluminum midrange, between two 5.25” aluminum woofers. The tradeoff: On-axis response is among the least even of any center here (1.34dB average deviation), and its listening window spans 5.7dB from 300Hz to 5kHz, the widest spread of any center here, which colors voices.
Buy the KEF Q6 Meta. It is rated higher for sound quality, and the $50.99 saving on the ELAC Uni-Fi Reference UCR52 is not enough to make up the difference.

Older models: the KEF Q250c (ranked lower, rated 3.9/5) and the KEF Q650c (ranked lower, rated 3.7/5).
Pros: A true three-way center with a Uni-Q coaxial driver (0.75” vented aluminium tweeter with MAT inside a 4” midrange) between two 6.5” bass drivers, replacing the two-way Q650c at about the same price. KEF’s Spinorama data shows the most consistent directivity of any center here (2.78dB directivity index deviation), so reflected sound matches the direct sound closely, with the listening window within 2.1dB from 300Hz to 5kHz. Bass reaches 60.7Hz (-3dB) and about 40Hz (-10dB), deep for a center at $850.
Cons: The only measurements are KEF’s own, and spinorama.org computes no preference score for them, so the ranking is an estimate. Sensitivity is a low 86dB and the impedance dips to 3.2 ohms, so it wants a receiver with some power in reserve. Maximum output is rated at 109dB.

ELAC Uni-Fi Reference UCR52: $799.00 each Amazon eBay
Pros: A three-way center with a 1” soft dome tweeter mounted concentrically in a 4” aluminum midrange, between two 5.25” aluminum woofers. The concentric driver keeps dispersion even in every direction: Audio Science Review measured about ±55 degrees both horizontally and vertically, so it works above or below a screen. Bass reaches 60.1Hz (-3dB) and about 44Hz (-10dB). Measured bass extension of 60.1Hz (-3dB).
Cons: On-axis response is among the least even of any center here (1.34dB average deviation), and its listening window spans 5.7dB from 300Hz to 5kHz, the widest spread of any center here, which colors voices. Sensitivity is a low 85dB. Preference score 3.40 without a subwoofer.
