Diamond 12.C

The DIAMOND 12.C brings cinema-quality vocal tangibility and depth to the Wharfedale DIAMOND 12 series home theatre system.

Designed as the centrepiece and perfect complement for the DIAMOND 12 series standmount (bookshelf) and floorstander models, the DIAMOND 12.C is compact, accurate and powerful.

Using dual 130mm (5”) KlarityTM drivers for accurate, refined mid-range and bass frequencies, while the 25mm (1”) dome tweeter delivers open and smoothly extended high frequencies opening up detail and depth for movies, sports and music.

Klarity a?ords focus

NEW Klarity™ cone material, formulated from a blend of Polypropylene and mica adds sti?ness to reduce ?exing, enabling a lightweight cone with high rigidity, low colouration and lightning-fast response.

Low colour and expression

The Klarity™ cone is ?tted with a low-damping surround, thereby achieving both low colouration and expressive dynamics. By simulating many di?erent cone shapes and adding ribs to provide further sti?ening, a ?at response curve was achieved without resorting to a high-damping surround, thereby striking the ideal balance.

A magnet of forces

A precision-made magnet system with an aluminium compensation ring to minimise the e?ect 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 ?bre 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 sti?er than the Kapton type associated with this price-class.

DIAMOND highs

The 25mm dome is made from a woven polyester ?lm 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 ?at and exposes the dome as much as possible; only a very short duct on the front plate balances the acoustic load and improves the SPL (sound pressure level) measurement.

A crossover of style

The crossover network uses an acoustic LKR 24dB topology. This includes air-core inductors of the type more commonly found in high-end speakers, selected because they produce the lowest distortion of all inductor types. As the resistance of the coil is higher than a standard laminated steel or ferrite core inductor, the magnetic structure of the mid/bass driver has been modi?ed to compensate, resulting in fast, clean bass with no distortion from the inductor.

Brace yourself

Inside the cabinet, Intelligent Spot Bracing connects opposite walls with a speci?c form of the wood brace to achieve an optimal reduction of cabinet resonance. These braces are precisely modelled by computer simulation to improve upon the commonplace ‘?gure of eight’ brace, which may simply transfer resonance from one wall to another.
