# Wharfedale Diamond 12.3: specs and price

**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.), as of 2026-07-11.
**Brand:** Wharfedale
**Deskmark:** Gold Deskmark — pay-blind category standing 95/100, #2 of 9 in class (independent, computed from sourced data, never for sale).

## What reviewers say

Only one whitelisted tester, What Hi-Fi, published a hands-on review of this exact model; it is a qualitative listening test with no lab measurements. It rates the Diamond 12.3 a five-star Award winner: refined, balanced and entertaining for the price, with the only real caveat being they need space from walls to sound their best. (Based on 1 review, 1 lab-tested, 2025-10-16.)

Praised: Superbly balanced, refined presentation for the price; Expressive, articulate midrange with seamless driver integration; Pleasing build and finish.
Flagged: Fussy positioning: sound best ~90cm from the rear wall and at least 70cm from side walls.
Disagreement: No cross-source comparison is possible — only What Hi-Fi qualifies as a whitelisted tester for this exact model. What Hi-Fi itself lists 'nothing at this price' under cons, so the only downside it notes is careful positioning rather than any sonic flaw.
