WHARFEDALE Diamond 12.4 Floorstanding Loudspeakers

The powerhouse model of the Wharfedale DIAMOND 12 series, the DIAMOND 12.4 is the room-filling, chest-pounding, largest model in the series. For larger, more powerful systems and cinema-style home theatre experiences, the DIAMOND 12.4 will fill your room with an impactful, immersive performance. Wharfedale Diamond 12.4 Floorstanding Loudspeakers 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’. 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. 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.
