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 Sonus Faber Lumina Center I ranks #65, rated 3.5/5, at $799, $50.99 cheaper, which does not close the gap in sound quality.
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 Sonus Faber Lumina Center I does well: Iconic DAD (Damped Apex Dome) 1.1-inch tweeter and dual 4.75-inch natural cellulose pulp woofers with front reflex port. Watch for: 4-ohm nominal impedance requires adequate amplifier drive.
Buy the KEF Q6 Meta. It is rated higher for sound quality, and the $50.99 you would save on the Sonus Faber Lumina Center I does not close the gap.

KEF Q6 Meta: $849.99 each Amazon eBay
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.

Sonus Faber Lumina Center I: $799.00 Estimated Crutchfield eBay
Pros: Iconic DAD (Damped Apex Dome) 1.1-inch tweeter and dual 4.75-inch natural cellulose pulp woofers with front reflex port. Delivers warm, articulate vocal clarity and luxury handcrafted Italian cabinet aesthetics.
Cons: 4-ohm nominal impedance requires adequate amplifier drive. 2-way horizontal driver arrangement causes off-axis crossover cancellation. Rating estimated based on Lumina series measurements.
