Wharfedale Diamond 12.2 Speakers
Still compact but with increased cabinet volume and driver size for even more potency, the Wharfedale DIAMOND 12.2 offers a little more from a traditional standmount (or bookshelf) speaker format and embodies the history and performance values of the Wharfedale DIAMOND series.
Perfect for larger rooms and more powerful 2-channel hi-fi systems, the DIAMOND 12. features a high-performance 150mm (6.5”) KlarityTM driver for extended, tight bass, and a superb 25mm (1”) woven polyester dome tweeter for open and smoothly extended high frequencies.
The 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 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.
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.
