While the Diamond 11 has a curved look, the Diamond 12 with its angular appearance suggests greater precision and enhanced dynamics. This Diamond model looks completely different from its predecessor and also differs in sound. This is another stunning Diamond bookshelf speaker that is basically one of the cheaper two-way bookshelf speakers. Wharfedale Diamond 12.2 bass reflex speaker testing Speaker sensitivity 88 dB, recommended amplifier power 20-120W, maximum sound pressure (SPL) 96dB, frequency response (+/- 3dB) 50Hz ~ 20kHz, dimensions (L x W x D) 335 x 200 x (285 + 28) mm, the weight is 8.2 kg / pc. The stiffeners were accurately modeled by computer simulation for this purpose. Inside the cabinet, Intelligent Spot Bracing optimally reduces cabinet resonance. Because the coil resistance is greater than a conventional laminated steel or ferrite core inductor, the magnetic structure of the mid / deep bass drive has been modified, resulting in fast, clean bass without distorting the inductor. The crossover system uses an acoustic LKR 24dB topology, which results in the least distortion. The sound coil is wound on a high-performance epoxy / fiberglass spool, which is extremely unusual for speakers in this price range. The magnetic system is equipped with an aluminum compensation ring to minimize distortions when the voice coil moves. This is said to contribute to extended yet tight bass and reduce hue and performance speed. The stiffness of the cone is further increased by the ribs formed on its surface. Made from a blend of polypropylene and mica, the Klarity cone is rigid, lightweight, and secure. The Diamond features 12 high-performance 150mm KlarityTM drives for extended, tight bass, and anticipated 25mm woven polyester dome tweeter for clean and extended high frequencies. Perfect for larger rooms and more powerful 2-channel hi-fi systems. Its size still remained compact, but the speaker box volume and drive size were increased for even greater efficiency. Wharfedale Wireless Works was founded in 1932 by Gilbert Briggs and has since become one of Britain’s leading manufacturers of audiophile equipment, particularly speakers.
