Wharfedale Diamond 12.2 Bookshelf Speaker – pair

Wharfedale Diamond 12.2 Bookshelf Speaker – pairPlease confirm available colours before handStill 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.Klarity affords focusNEW 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 expressionThe 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 forcesA 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 crossover of styleThe 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 fairThe 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 identifiable characteristics of the cabinet’s ‘sound’. Even the resonant properties of the glue between the layers was measured to determine the optimum combination.Specifications:General description2-way bookshelf speakerEnclosure typebass reflexTransducer complement2-wayBass driver6.5″(150mm) advanced PP ConeTreble driver1″(25mm) Textile DomeAV shieldNoSensitivity(2.83V @ 1m)88dBRecommended amplifier power20-120WPeak SPL96dBNominal impedance8Ω CompatibleMinimum impedance4.0ΩFrequency response(+/-3dB)50Hz ~ 20kHzBass extension(-6dB)43HzCrossover frequency2.0kHzCabinet Volume (in litres)11.8LDimensions ( H x W x D )335 x 200 x (285+28) mmNet weight8.2kg/pcs
