For larger, more powerful systems and cinema-style home theatre experiences, the DIAMOND 12.4 fills your room with an impactful, immersive performance – this open-box unit is finished in Walnut Pearl.\u003c\/p\u003e\n\u003cp\u003eConfigured in a 2.5-way system with exceptional crossover technology, the DIAMOND 12.4 utilises dual 150mm (6.5\") Klarity™ drivers for impactful yet refined mid-range and bass frequencies, while the 25mm (1\") dome tweeter delivers open and smoothly extended high frequencies.\u003c\/p\u003e\n\u003ch3\u003eKlarity Affords Focus\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch3\u003eLow Colour and Expression\u003c\/h3\u003e\n\u003cp\u003eThe Klarity™ cone is fitted with a low-damping surround, achieving both low colouration and expressive dynamics. By simulating many different cone shapes and adding ribs for further stiffening, a flat response curve was achieved without resorting to a high-damping surround, striking the ideal balance.\u003c\/p\u003e\n\u003ch3\u003eA Magnet of Forces\u003c\/h3\u003e\n\u003cp\u003eA precision-made magnet system with an aluminium compensation ring minimises the effect of variations in inductance as the voice coil travels, contributing to an absence of distortion and intermodulation generated by the motor system.\u003c\/p\u003e\n\u003ch3\u003eA Voice Coil Beyond This Class\u003c\/h3\u003e\n\u003cp\u003eThe voice coil is wound on a high-power epoxy\/glass fibre bobbin, highly unusual in speakers at this price level. This avoids adding eddy currents and delivers greater power handling than an aluminium bobbin, while being much stiffer than the Kapton type associated with this price class.\u003c\/p\u003e\n\u003ch3\u003eDiamond Highs\u003c\/h3\u003e\n\u003cp\u003eThe 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 front plate have been optimised for wide dispersion and uncompressed behaviour; a flat front plate exposes the dome as much as possible, with only a very short duct balancing the acoustic load and improving SPL measurement.\u003c\/p\u003e\n\u003ch3\u003eA Crossover of Style\u003c\/h3\u003e\n\u003cp\u003eThe crossover network uses an acoustic LKR 24dB topology, including air-core inductors of the type more commonly found in high-end speakers, chosen because they produce the lowest distortion of all inductor types. As the coil resistance 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.\u003c\/p\u003e\n\u003ch3\u003eFirm and Fair\u003c\/h3\u003e\n\u003cp\u003eThe DIAMOND 12.4'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 own sound, with even the resonant properties of the glue between layers measured to determine the optimum combination.\u003c\/p\u003e\n\u003ch3\u003eBrace Yourself\u003c\/h3\u003e\n\u003cp\u003eInside the cabinet, Intelligent Spot Bracing connects opposite walls with a specific form of wood brace to achieve an optimal reduction of cabinet resonance. These braces are precisely modelled by computer simulation to improve upon the commonplace \"figure of eight\" brace, which may simply transfer resonance from one wall to another.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnclosure Type:\u003c\/strong\u003e Bass reflex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBass Driver:\u003c\/strong\u003e 6.5\" (150mm) advanced PP Cone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMidrange Driver:\u003c\/strong\u003e 6.5\" (150mm) advanced PP Cone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTreble Driver:\u003c\/strong\u003e 1\" (25mm) Textile Dome\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAV Shield:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensitivity (2.83V @ 1m):\u003c\/strong\u003e 89 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Amplifier Power:\u003c\/strong\u003e 30 – 200 W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePeak SPL:\u003c\/strong\u003e 102 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Impedance:\u003c\/strong\u003e 8Ω Compatible\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Impedance:\u003c\/strong\u003e 5Ω\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency Response (+\/-3dB):\u003c\/strong\u003e 40 Hz – 20 kHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBass Extension (-6dB):\u003c\/strong\u003e 35 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrossover Frequency:\u003c\/strong\u003e 2.1 kHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCabinet Volume:\u003c\/strong\u003e 40.8 L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (H × W × D):\u003c\/strong\u003e (1100 + 50) × 200 × (350 + 28) mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNet Weight:\u003c\/strong\u003e 22.4 kg per speaker\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Wharfedale","offers":[{"title":"Walnut Pearl","offer_id":54833726488899,"sku":"W-DIA12.4-WP-OB","price":589.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0278\/4696\/7399\/products\/WharfedaleDiamond12.4FloorstandingSpeakerPair-WalnutPearl-A.jpg?v=1636569672","url":"https:\/\/www.hifihut.ie\/products\/wharfedale-diamond-12-4-floorstanding-speaker-pair-open-box-walnut-pearl","provider":"HiFiHut","version":"1.0","type":"link"}
