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 Arendal Sound 1723 Center THX ranks #51, rated 3.8/5, and costs $1,400, which makes this an easy call rather than a real tradeoff.
What the Monitor Audio Silver Centre 8G does well: 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. 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 Monitor Audio Silver 50 7G and the 8G range.
What the Arendal Sound 1723 Center THX does well: The center of the THX Ultra certified 1723 series, using the same 28mm waveguide tweeter as the measured 1723 Monitor THX between two 8” woofers. 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 1723 Monitor THX and the measured Arendal Sound 1961 Center.
Buy the Monitor Audio Silver Centre 8G. It is rated higher for sound quality than the Arendal Sound 1723 Center THX 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; Arendal Sound 1723 Center THX 3.4 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.

Arendal Sound 1723 Center THX: $1,400 each Estimated Arendal Sound eBay
Same family: the Arendal 1723 Bookshelf S THX (smallest bookshelf, rated 4.2/5), the Arendal Sound 1723 Monitor S THX (bookshelf, rated 4.1/5), the Arendal Sound 1723 Monitor THX (largest bookshelf, rated 4.2/5), the Arendal Sound 1723 Tower S THX (smaller floorstanding, estimated 4.2/5), the Arendal Sound 1723 Tower THX (larger floorstanding, estimated 4.3/5) and the Arendal Sound 1723 Center S THX (smaller center, ranked lower, estimated 3.7/5).
Pros: The center of the THX Ultra certified 1723 series, using the same 28mm waveguide tweeter as the measured 1723 Monitor THX between two 8” woofers. Arendal rates it to 35Hz (-6dB) with 89dB sensitivity, so it matches the towers for dynamics in a large home theater.
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 1723 Monitor THX and the measured Arendal Sound 1961 Center. With a woofer either side of the tweeter, dispersion narrows for seats far off-center. It is 635mm wide and 26.7kg.
