Clarity affords focus

As with all DIAMOND 12 models, the DIAMOND 12 3D uses the famous KlarityTM polypropylene cones that are renowned for their characteristically low distortion and controlled 'breakup'.

Low color 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 coloration 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 aluminum compensation ring to minimize 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 fiber 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 aluminum 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 optimized for wide dispersion and uncompressed behavior. The front plate is flat and exposed
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 modeled by
computer simulation to improve upon the common place 'figure of
eight' brace, which can have the effect of transferring resonance from one wall to another.
