Short answer: the RSL CG23M, though neither ranks well in its class. It ranks #131 of 168 bookshelf speakers by sound quality, rated 2.6/5, at $298. The Cambridge Audio Minx Min 22 ranks #140, rated 2.4/5, at $258, $40 cheaper, a saving that is not big enough to make up the sound-quality gap. Both are rated below 3.0/5 among the 168 bookshelf speakers; for better sound, the Ascend Acoustics HTM-200SE2 ranks #7 at $368.
Why pick the RSL CG23M: RSL’s current MTM monitor, two 4” mineral-filled aramid woofers around a 1” silk dome tweeter in a Compression Guide cabinet, rated at 89dB so it is easy to drive. The tradeoff: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers.
Why pick the Cambridge Audio Minx Min 22: A taller Cambridge Audio Minx Min 12 with a second BMR driver for more output, still small enough for a shelf or wall bracket at 1.7 lbs (0.75 kg). The tradeoff: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers.
Buy the RSL CG23M. It is rated higher for sound quality, and the $40 you would save on the Cambridge Audio Minx Min 22 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: RSL CG23M 2.2 to 3.0; Cambridge Audio Minx Min 22 2.0 to 2.8). Treat this verdict as provisional.

The Two Speakers In Full
RSL CG23M: $298 per pair Estimated RSL eBay
Older model: the RSL CG23 (estimated 2.4/5). See every RSL CG generation.
Same family: the RSL CG3M (smaller bookshelf, ranked lower, estimated 2.4/5).
Pros: RSL’s current MTM monitor, two 4” mineral-filled aramid woofers around a 1” silk dome tweeter in a Compression Guide cabinet, rated at 89dB so it is easy to drive. It replaced the CG23 and works upright as a main or surround speaker or on its side as a center.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers. Rated only from 80Hz, so it needs a subwoofer, and its 4 ohm load suits receivers set to 6 or 8 ohms as RSL recommends.
