Wharfedale Diamond 12 3D Atmos Surround Speakers - Black

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

DIAMOND highs

The 25mm dome 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, with a short duct to balance the acoustic load and improve the SPL (sound



pressure level) measurement.

Brace yourself




Inside the cabinet, Intelligent Spot Bracing connects opposing walls
with a specific form of wood brace to achieve optimal reduction of
cabinet resonance. These braces are precisely modelled by
computer simulation to improve upon the commonplace ‘figure of
eight’ brace, which can have the effect of transferring resonance from one wall to another.
