Diamond 12.C Centre Speaker

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 affords focus

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

Low colour and expression

The Klarity™ cone is fitted with a low-damping surround, thereby achieving both low colouration and expressive dynamics. By simulating many different cone shapes and adding ribs to provide further stiffening, a flat 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 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 associated with this price-class.

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 have been optimised for wide dispersion and uncompressed behaviour. The front plate is flat 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 modified to compensate, resulting in fast, clean bass with no distortion from the inductor.

Firm and fair

The DIAMOND 12.C's closed-box enclosure is precisely sized so that the internal volume works in harmony with the drive unit system to deliver the desired sonic result. A multi-layered sandwich design subdues the identifiable characteristics of the cabinet's 'sound'. Even the resonant properties of the glue between the layers was measured to determine the optimum combination.

Brace yourself

Inside the cabinet, Intelligent Spot Bracing connects opposite walls with a specific 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 'figure of eight' brace, which may simply transfer resonance from one wall to another.

Frequently Asked Questions

Where should the Diamond 12.C go in a home cinema?

The Diamond 12.C is a dedicated centre channel — sit it directly below or above the screen, aligned with your front left/right speakers and angled toward ear height at the main seat. It anchors on-screen dialogue so voices stay clear and locked to the picture.

What amplifier should I pair with the Diamond 12.C?

The Diamond 12.C presents a nominal 8Ω load and 90dB sensitivity, and Wharfedale recommends roughly 20-120W per channel. A quality integrated amplifier or AV receiver in that range drives it cleanly without strain — aim for clean, stable power rather than maximum wattage.

What finishes does the Diamond 12.C come in?

The Diamond 12.C is available in Walnut, Black, Light Oak and White. All finishes are the same speaker acoustically — choose whichever best suits your room. Every option is in stock with free Australian shipping.
