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 Bowers & Wilkins HTM6 S3 ranks #79, rated 3.4/5, and costs $899, so there is little reason to consider the other one.
The KEF Q6 Meta is the better-sounding pick. 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 catch: The only measurements are KEF’s own, and spinorama.org computes no preference score for them, so the ranking is an estimate.
What the Bowers & Wilkins HTM6 S3 does well: Decoupled 1-inch Titanium Dome tweeter and twin 5-inch Continuum cone bass/midrange drivers. Watch for: Exhibits characteristic Bowers & Wilkins rising treble profile on-axis.
Buy the KEF Q6 Meta. It is rated higher for sound quality than the Bowers & Wilkins HTM6 S3 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

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.
