Overview Wharfedale Diamond 12.2 speakers
Another compact model, but with increased enclosure volume and speaker size, the Wharfedale DIAMOND 12.2 offers increased performance from a traditional bookshelf speaker format, and embodies the historic values and performance of the Wharfedale DIAMOND series.
Perfect for larger rooms and more powerful two-channel hi-fi systems, the DIAMOND 12.2 features a high-performance 6.5" (150mm) Klarity™ driver for extended bass and a superb 25mm polyester dome tweeter for extended highs and open.
A reel beyond its class
The coil is wound on a high-strength epoxy/fiberglass core, very unusual for speakers at this price level. This has the advantage of not adding eddy currents and offers superior power handling over an aluminum spool, while being much stiffer than the Kapton type.
The 25mm dome is made from a polyester film with a high-loss coating to deliver open high frequencies. The magnet system and front plate have been optimized for wide dispersion and uncompromising behavior. The front plate is flat and exposes the dome as much as possible; only a very short front panel channel balances the acoustic load and improves SPL measurements.
The crossover network uses an LKR 24dB acoustic topology. This includes inductors that are often found on high-end speakers, chosen because they produce the least distortion. As the coil resistance is higher than a standard laminated steel or ferrite, the magnetic structure of the mid/bass drivers has been modified to compensate, resulting in a fast, clean bass with no distortion from the inductor.
The rear-port enclosure of the DIAMOND 12.2 speakers is precisely dimensioned so that the internal volume works in harmony with the driver unit system to deliver the Doric sonic result. A multi-layer sandwich design provides the identifiable characteristics of the cabinet's sound. Even the resonant properties of the glue between the layers was measured to determine the optimal combination.
Inside the enclosure, Intelligent Spot Bracing connects the opposite walls with a specific form of wood reinforcements to obtain optimal resonance reduction. These reinforcements are precisely modeled by computer simulations to improve the usual "figure of eight" reinforcement, which simply transfers the resonance from one wall to the other.
