Diamond 12.3 -Floorstanding Speakers OPEN BOX (Pair)

The Wharfedale Diamond 12.3 is one of the most acclaimed floorstanding speakers in its class, combining refined sound quality, modern engineering, and exceptional value. Widely recognized as a benchmark in entry-to-mid-level hi-fi, it delivers a performance that rivals more expensive systems.

This speaker uses a 2.5-way design with dual 130mm (5") Klarity™ drivers and a 25mm soft dome tweeter, ensuring smooth integration between bass, midrange, and treble.

The Klarity™ cone—made from a blend of polypropylene and mica—offers low coloration, high rigidity, and fast transient response, resulting in clean, accurate sound reproduction.

With a frequency response of approximately 45Hz–20kHz, the Diamond 12.3 delivers surprisingly deep bass for its size, along with articulate mids and refined highs.

Its well-braced cabinet design minimizes resonance and distortion, while the slim, elegant form factor allows it to integrate easily into modern living spaces.

These speakers are highly versatile—equally suited for 2-channel music listening or home theater systems—and are compatible with a wide range of amplifiers thanks to their 89dB sensitivity and 8-ohm nominal impedance.

The Diamond 12.3 has also earned multiple awards and is frequently cited as one of the best budget floorstanding speakers available, known for its smooth, refined, and engaging sound signature.
