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.
Diamond 12 Series:
For many decades, Wharfedale has been famous for fusing even-handed neutrality and transparency with captivating clarity and expression. The Wharfedale DIAMOND 12 embodies that sonic goal. The DIAMOND 12 series represents affordable, authentic hi-fi loudspeakers that truly capture the spirit of music, whatever you play – from rock to classical, jazz to electronica – whilst conveying the recording with truth and accuracy, as all great ‘hi-fi’ should. Developed in collaboration with Karl-Heinz Fink – one of the most successful loudspeaker designers on the planet. Classic DIAMOND price points, industrial design that’s cool and contemporary yet still distinctly Wharfedale, and sound that delivers, yet another, new ‘budget’ benchmark through exceptional acoustic design and engineering.
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. 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 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’. 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.
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 behavior. 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.
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.
The DIAMOND 12’s rear-ported 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. Inside the cabinet, Intelligent Spot Bracing connects opposite 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 commonplace ‘ﬁgure of eight’ brace, which may simply transfer resonance from one wall to another.
