Product description
Since 1982, Wharfedale's Diamond speakers have been known as the gateway to true hi-fi sound. Combining outstanding performance with a smart price, the series has won numerous awards and accolades. The Diamond 12 series continues that tradition, taking affordable quality to the next level.
The Diamond 12.3s are the most compact floorstanding speakers in the series, offering a perfect balance of refinement and power. Featuring two 130mm Klartity™ drivers and a 25mm woven polyester dome tweeter, they deliver vibrant, detailed, and natural sound—ideal for 2-channel hi-fi systems or as front speakers in a home theater setup.
The cabinet construction is carefully designed with Intelligent Spot Bracing, where opposing walls are connected by specially shaped wooden bracing. This minimizes resonance and ensures a clean, controlled sound with a full, immersive tone.
