They are terrifically accomplished for the money and good enough to claim a space in the Diamond's hall of fame.

They're smooth, even-handed and wonderfully refined for the money.

the 12.3 aren't massive speakers, but they still perform best if given a little room to breathe

Specifications

Price (US)	Not published No per-single US MSRP could be sourced verbatim. WharfedaleUSA (official US store) lists the Diamond 12.3 at "$999.00 $1,198.00" per pair, labelled "[Last Call]" (i.e. $999.00/pair clearance, reduced from $1,198.00/pair). The What Hi-Fi review lists it "Tested at ... $798" (per pair). Because only per-pair US figures are stated and they conflict ($798 vs $1,198), and the field requires per-single US MSRP, priceUsd is left null.

Source: wharfedale.co.uk (verified 2026-07-11) · corroborated by wharfedaleusa.com. Source (wharfedale.co.uk) confirms the exact model "DIAMOND 12.3" (not the 12.3i variant) and its Specifications table verbatim: 2.5-way, enclosure type "bass reflex", dual 5"(130mm) Advanced PP cones, 1"(25mm) Textile Dome tweeter, sensitivity 89dB (2.83V@1m), "8 ohm compatible" nominal impedance, frequency response 45Hz~20kHz (+/-3dB), crossover 2.2kHz, recommended amp power 30-150W, and net weight 19.5kg/pcs. Corroboration (wharfedaleusa.com, the official US store) confirms the same non-"i" Diamond 12.3 and supplies the imperial per-speaker weight used here (Net Weight: 42.9 lbs) plus US pricing ($999.00/pair "Last Call", was $1,198.00/pair); it quotes sensitivity as 87.5dB versus the manufacturer's 89dB, so the manufacturer figure was used. heightIn is null because the only verbatim inch height (38.38") is the overall dimension including the 50mm plinth/feet (UK spec: 925+50 mm), while the methodology requires cabinet height excluding plinth; no per-single US MSRP is stated so priceUsd is null (What Hi-Fi's independent review also corroborates 89dB, 8ohms, 45Hz-20kHz, and the 25mm woven-polyester soft dome).
