Central speaker WHARFEDALE Diamond 12.C

The DIAMOND 12.C brings cinema-quality vocal tangibility and depth to the Wharfedale DIAMOND 12 series home theatre system. Designed as the centrepiece and perfect complement for the DIAMOND 12 series standmount (bookshelf) and floorstander models, the DIAMOND 12.C is compact, accurate and powerful. Using dual 130mm (5”) KlarityTM drivers for accurate, refined mid-range and bass frequencies, while the 25mm (1”) dome tweeter delivers open and smoothly extended high frequencies opening up detail and depth for movies, sports and music. ]]>

DIAMOND 12 Series

Innovative, High-performance, Whole Home Audio Solution For Music Lovers Of All Levels
In the early 1980s, Wharfedale created the blueprint for modern ‘budget’ hi-fi speakers when it made the first-ever DIAMOND. Through successive generations, the Wharfedale DIAMOND has remained the most famous name in budget hi-fi speakers
worldwide. The launch of a new DIAMOND range is always a major hi-fi event and this campaign will introduce the latest generation of DIAMOND loudspeakers to the world.
The Wharfedale DIAMOND line is “one of the most successful speaker ranges of all time” (What Hi-Fi? 2015). It’s also one of the most enduring – there have been Wharfedale DIAMOND speakers on the market for the past 38 years, updated from one generation to the next.
The all-new DIAMOND 12 Series is the best DIAMOND range yet, developed in collaboration with Karl-Heinz Fink – one of the most successful loudspeaker designers on the planet. Classic DIAMOND price points, industrial design that’s cool
and contemporary yet still distinctly Wharfedale, and sound that delivers a new ‘budget’ benchmark through exceptional acoustic design and engineering – the DIAMOND 12 Series is one of the most exciting audio product launches of 2020.

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.

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.

Firm and fair

The DIAMOND 12.1 ’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 ‘sound’. Even the resonant properties of the glue between the layers was measured to determine the optimum combination.
