Short answer: the SVS Prime Center. Both are rated 3.4/5 for sound quality (#69 and #82 of 98 center channel speakers), and the SVS Prime Center costs $449 against $499 for the PSB Alpha C10, so with nothing between them on sound quality, price settles it.
The case for the PSB Alpha C10: 0.75-inch anodized aluminum dome tweeter with custom waveguide paired with dual 5.25-inch textured polypropylene woofers. The tradeoff: Standard horizontal 2-way MTM crossover creates dialogue notches for listeners seated far off-axis.
What the SVS Prime Center does well: A three-way center with a 3.5” midrange between the 1” aluminum tweeter and two 5.25” woofers, which avoids the side-to-side cancellation of two-way centers: Erin’s Audio Corner measured the widest horizontal coverage of any center here, about ±75 degrees. The catch: On-axis response is uneven (1.29dB average deviation), and the preference score is 3.34 without a subwoofer and 6.0 with one.
Buy the SVS Prime Center. Both are rated the same for sound quality, and it costs $50 less than the PSB Alpha C10.
