Short answer: the Monitor Audio Silver Centre 8G. It ranks #38 of [131 center channel speakers](/passive/center/#monitor-audio-silver-centre-0 lbs (8 g)) by sound quality, rated 4.0/5, at $1,200; the MartinLogan Motion XT C100 ranks #44, rated 3.9/5, and costs $1,279.99, so there is little reason to consider the other one.
Why pick the Monitor Audio Silver Centre 8G: A sealed 3-way center for the Silver 8G range, with the 3” C-CAM midrange placed directly below the 25mm Gold Dome tweeter between two 6” bass drivers. 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 Monitor Audio Silver 50 7G and the 8G range.
Why pick the MartinLogan Motion XT C100: Flagship 2.5-way center channel featuring larger Gen2 FMT XT tweeter with 40% more surface area and dual 6.5-inch Nomex-reinforced Kevlar woofers. The catch: Large 24-inch cabinet depth and width require substantial shelving.
Buy the Monitor Audio Silver Centre 8G. It is rated higher for sound quality than the MartinLogan Motion XT C100 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: Monitor Audio Silver Centre 8G 3.6 to 4.3; MartinLogan Motion XT C100 3.7 to 4.1). Treat this verdict as provisional.

Monitor Audio Silver Centre 8G: $1,200.00 each Estimated Audio Advice eBay
Older model: the Monitor Audio Silver C250 7G (ranked higher, estimated 4.1/5). See every Monitor Audio Silver generation.
Same family: the Monitor Audio Silver 50 8G (smaller bookshelf, estimated 4.2/5), the Monitor Audio Silver 100 8G (larger bookshelf, estimated 4.1/5), the Monitor Audio Silver 300 8G (smaller floorstanding, estimated 4.2/5) and the Monitor Audio Silver 500 8G (larger floorstanding, estimated 4.2/5).
Pros: A sealed 3-way center for the Silver 8G range, with the 3” C-CAM midrange placed directly below the 25mm Gold Dome tweeter between two 6” bass drivers. That vertical midrange and tweeter layout keeps dialogue consistent across a wide sofa, and the sealed box works close to a wall or inside furniture. Sensitivity is 89dB.
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 Monitor Audio Silver 50 7G and the 8G range. Bass is rated only to 66Hz (-6dB), so it relies on a subwoofer, and the impedance falls to 4.0 ohms at 160Hz.
