Short answer: the Arendal Sound 1723 Monitor S THX. Both are rated 4.1/5 for sound quality (#67 and #71 of 214 bookshelf speakers), and the Arendal Sound 1723 Monitor S THX costs $2,200 against $2,300 for the Monitor Audio Silver 100 8G, with sound quality a draw, the lower price decides it.
Why pick the Arendal Sound 1723 Monitor S THX: A THX-certified two-way with twin 6.5-inch woofers around a waveguided 28mm tweeter, and port plugs that let you run it sealed, with one vent or two to suit the room. The catch: In the configuration measured, the bass response starts to fall early, about 77Hz at -3dB, though it keeps going to about 50Hz at -6dB and 33Hz at -10dB, so it benefits from a subwoofer or placement near a wall.
What the Monitor Audio Silver 100 8G does well: The 2026 Silver 100 becomes a three-way: an 8” C-CAM RST III woofer, a 3” C-CAM midrange and a 25mm C-CAM gold dome tweeter in a waveguide, with Silent Flow ports and 33Hz (-6dB) in-room bass. 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 its measured predecessor.
Buy the Arendal Sound 1723 Monitor S THX. Both are rated the same for sound quality, and it costs $100 less than the Monitor Audio Silver 100 8G.
About the ratings: the Monitor Audio Silver 100 8G’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 3.8 to 4.4, so this verdict could change once it is measured.

Same family: the Arendal 1723 Bookshelf S THX (smaller bookshelf, ranked higher, rated 4.2/5), the Arendal Sound 1723 Monitor THX (larger bookshelf, ranked higher, 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), the Arendal Sound 1723 Center S THX (smaller center, estimated 3.7/5) and the Arendal Sound 1723 Center THX (larger center, estimated 3.8/5).
Pros: A THX-certified two-way with twin 6.5-inch woofers around a waveguided 28mm tweeter, and port plugs that let you run it sealed, with one vent or two to suit the room. Erin’s Audio Corner measured a listening window within a 2.4dB span from 300Hz to 5kHz, a smooth listening window (0.77) and predicted in-room response (0.71), and a preference score of 5.07 that rises to 7.08 with an ideal subwoofer. Sensitivity is a healthy 88.7dB. Measured bass extension of 76.9Hz (-3dB).
Cons: In the configuration measured, the bass response starts to fall early, about 77Hz at -3dB, though it keeps going to about 50Hz at -6dB and 33Hz at -10dB, so it benefits from a subwoofer or placement near a wall. It is large and heavy for a stand-mount at 56.9cm tall and 18.7kg, presents a 4-ohm load, and is sold direct by Arendal.
