Wharfedale Diamond 12.3 Floorstanding Speaker

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.

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.
