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 Q Acoustics 5090 ranks #47, rated 3.7/5, at $799, $50.99 cheaper, a saving that is not big enough to make up the sound-quality gap.
Why pick 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.
Why pick the Q Acoustics 5090: Dual 4.5-inch C3 Continuous Curved Cone woofers paired with high-performance Point-2-Point internal bracing. The catch: Impedance drops to 3.2 ohms minimum at bass frequencies.
Buy the KEF Q6 Meta. It is rated higher for sound quality, and the $50.99 you would save on the Q Acoustics 5090 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.
