Short answer: the Sony SS-CS8 M2, though neither ranks well in its class. It ranks #122 of 131 center channel speakers by sound quality, rated 2.8/5, at $123; the Fluance Signature HFC ranks #129, rated 2.1/5, and costs $179.99, which makes this an easy call rather than a real tradeoff. Both are rated below 3.0/5 among the 131 center channel speakers, so if sound quality matters, consider the Polk Audio XT30 instead, ranked #65 at $139.
The Sony SS-CS8 M2 is the better-sounding choice. The matching center for Sony’s 2025 Core M2 speakers, with two 3.94” woofers either side of a 1” tweeter in a compact 430mm wide cabinet that fits under most TVs. The catch: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured Sony SS-CS5 M2.
What the Fluance Signature HFC does well: The center channel of Fluance’s Signature series, with two 5” glass fiber woofers either side of a 1” soft dome tweeter. Watch for: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured Fluance Signature HFS bookshelf, which had an uneven, colored response.
Buy the Sony SS-CS8 M2. It is rated higher for sound quality than the Fluance Signature HFC and costs less, so only choose the other one for a particular feature it does better.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: Sony SS-CS8 M2 2.4 to 3.2; Fluance Signature HFC 1.7 to 2.5). Treat this verdict as provisional.

The Two Speakers In Full
Sony SS-CS8 M2: $123.00 each Estimated Amazon eBay
Same family: the Sony SS-CS5 M2 (bookshelf, rated 3.2/5) and the Sony SS-CS3 M2 (floorstanding, estimated 3/5). See every Sony SS-CS generation.
Pros: The matching center for Sony’s 2025 Core M2 speakers, with two 3.94” woofers either side of a 1” tweeter in a compact 430mm wide cabinet that fits under most TVs. Sensitivity is 87dB, so any home theater receiver drives it.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured Sony SS-CS5 M2. The small woofers limit bass to 55Hz and maximum output, and the woofer and tweeter layout narrows dispersion for seats off to the side.

Fluance Signature HFC: $179.99 each Estimated Amazon eBay
Same family: the Fluance Signature HFS (bookshelf, rated 2.1/5) and the Fluance Signature HFF (floorstanding, estimated 2.4/5).
Pros: The center channel of Fluance’s Signature series, with two 5” glass fiber woofers either side of a 1” soft dome tweeter. Sensitivity is a high 92dB, so it is easy to drive and keeps up with the HFF towers.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured Fluance Signature HFS bookshelf, which had an uneven, colored response. The horizontal woofer and tweeter layout narrows dispersion off to the sides, and bass is rated only to 60Hz.
