The more compact of the Wharfedale DIAMOND 12 series floorstanding options, the DIAMOND 12.3 loses none of the accuracy and musicality of the standmount (bookshelf) options. With enhanced presence and power, the DIAMOND 12.3 is refined and the perfect, affordable floorstanding speaker for 2-channel hi-fi systems, or as the front pair of a seriously impressive home theatre system.
Configured in a 2.5 way system with exception crossover technology, the DIAMOND 12.3 utilises dual 130mm (5”) KlarityTM drivers for impactful yet refined mid-range and bass frequencies, while the 25mm (1”) dome tweeter delivers open and smoothly extended high frequencies.
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.
Brace yourself
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.

The CM8 is an elegantly proportioned, slimmed down version of the award-winning CM9. A true three-way loudspeaker that will appeal to discerning customers who demand the very best sound quality, but have limited space in which to achieve it.
Like all the models in the CM Series, the CM8 uses crossovers of remarkable simplicity and quality, so what you hear is that much closer to the sound of the original recording. In its functional perfection and understated elegance, itʼs nothing less than a masterpiece. Pure and simple.
All CM Series speakers come with chrome driver trims. Grilles attach magnetically, so there are no unsightly grille-mounting features to spoil the clean lines of the speakerʼs façade. For the finish, you can choose either one of two real-wood veneers in Rosenut or Wengé, the highly polished gloss black or the new stylish white.
30-200watt 8 Ohm
Dimensions: 990x200x300
ALSO AVAILABLE IN ROSENUT AND WENGE COLOR
