Diamond 12.3 Floor standing Speakers (Pair)
Call for Price
The more compact the Wharfedale DIAMOND 12 series floorstanding options, the DIAMOND 12.3 loses none of the accuracy and musicality of the stand mount (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 utilizes 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.
Diamond 12 3
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 coloration, and lightning-fast response.
Low color and expression
The Klarity™ cone is fitted with a low-damping surround, thereby achieving both low coloration and expressive dynamics. Simulating many different cone shapes and adding ribs to 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 aluminum compensation ring to minimize 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. Diamond 12 3 has the advantage of not adding eddy currents and delivering greater power handling than an aluminum bobbin, whilst also being much stiffer than the Kapton type associated with this price class.
Diamond 12 3 highs
The 25mm dome is made from a woven polyester film with a high-loss coating to deliver open and smoothly extended high frequencies. Diamond 12 3 magnet system and the front plate have been optimized 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.
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 modified to compensate, resulting in fast, clean bass with no distortion from the inductor.
Firm and fair
The Diamond 12 3 ’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 were measured to determine the optimum combination.
