They come in original packaging, with grilles and our standard 3 month warranty.
Wharfedale Say….
The true all-rounder, the Wharfedale Diamond 12.1 is a traditional standmount (or bookshelf) speaker that embodies the history and performance values of the Wharfedale Diamond series.
The perfect ‘affordable’ hi-fi speaker, the Diamond 12.1 offers the best of both worlds – compact size with power and detail.
Perfect for 2-channel hi-fi systems, thanks to its intricate performance but also compact and capable for immersive home theatre, the Diamond 12.1 is designed and certified to perform, regardless of room size and application.
The Diamond 12.1 features a high-performance 130mm Klarity™ driver for exceptional timing and refined bass. The superb 25mm woven polyester dome tweeter delivers open and smoothly extended high frequencies.
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.
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 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’.
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.
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.
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.
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.
Inside the cabinet, Intelligent Spot Bracing connects opposite walls with a specific form of the wood brace to achieve an optimal reduction of cabinet resonance. These braces are precisely modelled by computer simulation to improve upon the commonplace ‘figure of eight’ brace, which may simply transfer resonance from one wall to another.

Service

Established in 2003, 2ndhandhifi is the UKs largest stockist of used quality audio equipment. All items are checked before despatch and guaranteed for 30 days for ebay buyers to give you peace of mind that the item will arrive safely and work exactly as per ebay descriiptions.

This means that all items described as 'used' will be in good working order but may show minimal cosmetic marks resulting from everyday use. Any more significant cosmetic issues will be highlighted in the listing if present.
