Wharfedale Diamond 12.0 Bookshelf Speakers (Pair)

The ultra-compact speaker in the DIAMOND 12 series, the DIAMOND 12.0 features all of the same technology as its larger siblings but is designed for small-footprint hi-fi systems, or even as a high-performance, compact satellite speaker in home theatre systems.

The DIAMOND 12.0 features a high-performance 100mm (4”) Klarity^TM driver with a bass performance that exceeds its diminutive footprint, while the superb 25mm (1”) woven polyester dome tweeter brings open and smoothly extended high frequencies.

FEATURES

• 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’.
  
  
• 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.
  
  This has the advantage of not adding eddy currents and delivering greater power handling than an aluminium bobbin, whilst also being much stiffer than the Kapton type associated with this price-class.
  
  
• 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.
