Short answer: the Wharfedale Diamond 12.4i. It ranks #107 of 228 floorstanding speakers by sound quality, rated 4.2/5, at $1,498. The Wharfedale Diamond 12.3i ranks #133, rated 4.0/5, at $1,198, $300 cheaper, which does not close the gap in sound quality.
Why pick the Wharfedale Diamond 12.3i: An updated slim tower with twin 5 inch woofers that is easy to drive and plays full range in a medium room. The tradeoff: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers.
Why pick the Wharfedale Diamond 12.4i: Affordable floorstanding speakers with twin woofers and easy to drive sensitivity, filling a larger room without a subwoofer. The catch: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers.
Buy the Wharfedale Diamond 12.4i. It is rated higher for sound quality, and the $300 you would save on the Wharfedale Diamond 12.3i 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: Wharfedale Diamond 12.3i 3.7 to 4.3; Wharfedale Diamond 12.4i 3.9 to 4.5). Treat this verdict as provisional.
