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 MartinLogan Motion C10 ranks #44, rated 3.7/5, and costs $1,099.99, so there is not much of a tradeoff to weigh.
The case for the KEF Q6 Meta: 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 MartinLogan Motion C10 does well: McCracken-Vojtko 2.5-way crossover rolls off the outer woofer early, significantly mitigating horizontal lobing suckouts. The tradeoff: 4-ohm nominal impedance requires an amplifier capable of stable low-impedance drive.
Buy the KEF Q6 Meta. It is rated higher for sound quality than the MartinLogan Motion C10 and costs less, which makes it the one to get unless you need something the other one does better.

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.

MartinLogan Motion C10: $1,099.99 Estimated Crutchfield eBay
Pros: McCracken-Vojtko 2.5-way crossover rolls off the outer woofer early, significantly mitigating horizontal lobing suckouts. Gen2 Obsidian Folded Motion Tweeter provides smooth treble with high transient speed and low distortion.
Cons: 4-ohm nominal impedance requires an amplifier capable of stable low-impedance drive. Rating estimated based on measured Motion series sibling performance.
