The powerhouse model, the Wharfedale Diamond 12.4 Floorstanding Speakers are the room-filling, chest-pounding, largest model in the series. For more powerful systems and home theatre experiences, the Diamond 12.4 will fill your room with an impactful, immersive performance.
Configured in a 2.5-way system with exception crossover technology, the DIAMOND 12.3 uses dual 6.5-inch Klarity drivers for impactful yet refined mid-range and bass frequencies. The 1-inch dome tweeter delivers open and smoothly extended high frequencies.
Klarity affords focus
As with all Diamond 12 models, the Diamond 12.4 uses the famed Klarity polypropylene cones, which are renowned for their characteristically low distortion and controlled ‘breakup’.
Low colour and expression
To make Klarity, Wharfedale adds mica to the formulation. This increases stiffness compared to polypropylene alone and reduces flexing. This creates a lightweight cone with high rigidity, low colouration, and lightning-fast response—ideal for both accuracy and excitement.
A magnet of forces
A substantial, precision-made magnet system drives Klarity diaphragms, with an aluminium compensation ring to minimise the effect of variations in inductance as the voice coil travels. This contributes to an absence of distortion and intermodulation generated by the motor system.
A voice coil beyond this class
The voice coil winding is a high-power epoxy/glass fibre bobbin—highly unusual in speakers at this price level. This has the advantage of not adding eddy currents and delivering greater power handling than an aluminium bobbin, while also being much stiffer than the Kapton type.
DIAMOND highs
The 25mm dome is made from a woven polyester film with a high-loss coating to deliver open and smoothly extended high frequencies. The magnet system and the front plate are optimal for wide dispersion and uncompressed behaviour. The front plate is flat and exposes the dome as much as possible, with a short duct to balance the acoustic load and improve the SPL (sound pressure level) measurement.
Cabinet Bracing
Inside the cabinet, Intelligent Spot Bracing connects opposing walls with a specific form of wood brace to reduce cabinet resonance. These braces are precisely modelled by computer simulation to improve upon the ‘figure of eight’ brace, which can transfer resonance from one wall to another.
