Klarity affords focus
As with all DIAMOND 12 models, the DIAMOND 12 3D uses the famed KlarityTM polypropylene cones that renowned for their characteristically low distortion and controlled ‘breakup’.
Low colour and expression
To make KlarityTM, Wharfedale adds mica to the formulation. This increases stiffness compared to polypropylene alone, reducing flexing and enabling a lightweight cone with high rigidity, low colouration and lightning-fast response – ideal characteristics to deliver both accuracy and excitement.
A magnet of forces
The KlarityTM diaphragms are driven by a substantial, precision-made magnet system 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 is wound on 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, whilst also being much stiffer than the Kapton type.

DIAMOND highs
The 25mm dome 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
have been optimised 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.
Brace yourself
Inside the cabinet, Intelligent Spot Bracing connects opposing walls
with a specific form of wood brace to achieve optimal reduction of
cabinet resonance. These braces are precisely modelled by
computer simulation to improve upon the commonplace ‘figure of
eight’ brace, which can have the effect of transferring resonance from one wall to another.
