Diamond 12 Series speakers from Wharfedale

Working with Karl-Heinz Fink for the first time, Wharefedale’s Diamond 12 Series comprises three standmount speakers, two floorstanding models and a centre speaker for home cinema

Cone construction includes the company’s polypropylene-based Klarity but with added mica to increase stiffness compared to polypropylene alone, reducing flexing.

Polypropylene speaker cones are often combined with high-damping surrounds to achieve a smooth response curve. However, the hysteresis of these surrounds can restrict dynamics and make bass sound somewhat ‘soft’.

For the Diamond 12 Series, the aim was to combine the Klarity cone with a low-damping surround.

The Klarity diaphragms are driven by a substantial magnet system with an aluminium compensation ring to minimise the effect of variations in inductance as the voice coil travels.

The voice coil is wound on an epoxy/glass fibre bobbin.

The Diamond 12 Series’ treble unit sports a 25mm dome made from a woven polyester film. 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.

The cabinet walls are made from sections of wood fibre board of varying thickness, constructed in such a way as, “…to subdue the identifiable characteristics of the cabinet’s ‘sound’ and ensure the drivers’ output remains unsullied,” said the company. Inside the cabinet is Intelligent Spot Bracing.

Available from October, prices are:

  •  12.0 – £199 per pair 
  •  12.3 – £499 per pair 
  •  12.C – £229
  •  12.1 – £249 per pair

    The current Diamond 11 series didn’t require this “upgrade”. They are perfect as is, already.
    The new 12 series looks more like a replacement for the D 200 series sans the bottom firing subwoofer output. Many won’t like this as the bottom firing port was something that defined the D 200 and D 11 series and is confirmed by the experts as the step above the back firing port design.

    Totally unnecessary. I can see Walmart, Sears and other shopping centers flooded with these, discounted in about 6 months time to as low as 50%. I’ve seen this first hand with the older Diamond 10 series.

    Looks cheap, doesn’t add anything to beat the current 11’s.

    I’d agree with that, David. The 11.2’s are a very fine speaker and very musical too, unlike a lot of the current “ching and boom” recommended models.
