The more compact of the Wharfedale DIAMOND 12 series floorstanding options, the DIAMOND 12.3 loses none of the accuracy and musicality of the standmount (bookshelf) options. With enhanced presence and power, the DIAMOND 12.3 is refined and the perfect, affordable floorstanding speaker for 2-channel hi-fi systems, or as the front pair of a seriously impressive home theatre system. Configured in a 2.5 way system with exception crossover technology, the DIAMOND 12.3 utilises dual 130mm (5") KlarityTM drivers for impactful yet refined mid-range and bass frequencies, while the 25mm (1") dome tweeter delivers open and smoothly extended high frequencies. NEW KlarityT 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 KlarityT 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'.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. 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.
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. 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. 5(130mm) advanced PP Cone. Dimensions (H x W x D). (925+50) x 180 x (320+28) mm.
