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 Micca RB42-C ranks #130, rated 2.1/5, at $119.99. The price gap is small enough that the sound-quality ranking should decide it. 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.
Why pick the Micca RB42-C: The center channel of Micca’s Reference series, matching the measured Micca RB42 bookshelf with two 4” long-throw woofers and a 0.75” silk dome tweeter, and a crossover using film capacitors and air-core inductors with 18dB/octave slopes. The tradeoff: 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 Micca RB42, which scored 4.59 on Spinorama but had a recessed, uneven balance that held its rating down.
Buy the Sony SS-CS8 M2. It is rated higher for sound quality, and the $3.01 you would save on the Micca RB42-C does not close the gap.
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; Micca RB42-C 1.7 to 2.5). Treat this verdict as provisional.

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.

Micca RB42-C: $119.99 each Estimated Amazon eBay
Same family: the Micca RB42 (bookshelf, rated 2.3/5).
Pros: The center channel of Micca’s Reference series, matching the measured Micca RB42 bookshelf with two 4” long-throw woofers and a 0.75” silk dome tweeter, and a crossover using film capacitors and air-core inductors with 18dB/octave slopes. Its symmetrical cabinet also works upright as a front speaker.
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 Micca RB42, which scored 4.59 on Spinorama but had a recessed, uneven balance that held its rating down. Small 4” woofers limit bass and output, so a subwoofer is a must.
