The real all-rounder, the Wharfedale Diamond 12.1, is a traditional stand-mount (or bookshelf) speaker who embodies the history and performance values of the Wharfedale Diamond series.
The perfectly 'affordable' hi-fi speaker, the Diamond 12.1 offers the best of two worlds - compact format with strength and detail.
Perfect for 2-channel hi-fi systems, thanks to its complicated performance but also compact and suitable for compelling home theaters, the Diamond 12.1 is designed and certified to perform, regardless of the size of the room and the application.
The Diamond 12.1 is equipped with a high-quality 130 mm (5 ") Klarity Tm - Driver For exceptional timing and refined bass. The excellent 25mm (1") woven polyester dome tweeter supplies open and smoothly extended high frequencies.

New Klarity™ cone material, composed of a mix of polypropylene and mica adds firmness to reduce FL Exing, so that a lightweight cone is possible with a high stiffness, low coloring and lightning fast response.
Low color and expression
The Klarity ™Conus is equipped with a low-damping edge, so that both low staining and an expressive dynamic is achieved. By simulating many different cone forms and adding ribs for further reinforcement, a flat response curve was achieved without resorting to a strongly damping surround, so that the ideal balance was found.
A magnet from forces
An accurately manufactured magnet system with an aluminum compensation ring to minimize the effect of variations in induction during the course of the speaking coil. This contributes to the absence of distortion and intermodulation generated by the 'motor system'.
A speaking reel outside this class
The speaking coil is wrapped on a powerful coil of epoxy / fiberglass, which is very unusual in speakers of this price level. This has the advantage that it does not add swirl streams and produces greater load capacity than an aluminum coil, while it is also much stronger than the Kapton type that belongs to this price range.
The dome of 25 mm is made from a woven polyester foil with a high-loss coating to deliver open and even extended high frequencies. The magnet system and the front plate are optimized for broad distribution and uncompressed behavior. The front plate is flat and exposes the dome as much as possible; Only a very short tube on the front plate compensates 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 that occurs more often in high-end speakers, which have been selected because they produce the lowest distortion of all inductor types. Because the resistance of the coil is higher than a standard laminated sampling or ferrite core inductor, the magnetic structure of the MID / BASS driver is modified to compensate, resulting in a fast, clean bass without distortion by the inductor.
Sturdy and honest
The housing of the Diamond 12.1s at the back is exactly dimensioned that the internal volume in harmony works with the drive system to deliver the desired sonic result. A multi-layer sandwich construction ensures that the 'sound' of the cupboard is muted in no time. Even the resonant properties of the glue between the layers is measured to determine the optimum combination.
Inside the cabinet, Intelligent Spot Bracing connects opposite walls with a special shape of the wooden bracket to achieve optimum reduction of the cabinet resonance. These brackets are precisely modeled by means of computers simulation to improve the usual 'fihip of eight bracket, which can transfer the resonance from one wall to another.
