WHARFEDALE DIAMOND 12.3

Diamond 12.3
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 a?ords focus
NEW Klarity™ cone material, formulated from a blend of Polypropylene and mica adds sti?ness to reduce ?exing, enabling a lightweight cone with high rigidity, low colouration and lightning-fast response.

Low colour and expression
The Klarity™ cone is ?tted with a low-damping surround, thereby achieving both low colouration and expressive dynamics. By simulating many di?erent cone shapes and adding ribs to provide further sti?ening, a ?at 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 e?ect of variations in inductance as the voice coil travels. This contributes to an absence of distortion and intermodulation generated by the ‘motor system’.

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 modi?ed to compensate, resulting in fast, clean bass with no distortion from the inductor.

Firm and fair
The DIAMOND 12.1 ’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 identi?able 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 speci?c 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 ‘?gure of eight’ brace, which may simply transfer resonance from one wall to another.
