WHARFEDALE Diamond 12.1i Bookshelf Loudspeakers

Klarity affords focus
The DIAMOND 12i mid/bass driver cones remain unchanged and are made from Klarity™, a special blend of polypropylene and mica that provides excellent stiffness and low distortion. This results in a cone that is lightweight, well-damped, and very responsive, delivering natural, expressive dynamics and precise transient response.

Low colour and expression
A low-damping surround enhances the cone’s efficiency and dynamic range, while ribbed shaping and profile simulation ensure a smooth, linear frequency response without added distortion.

A magnet of forces
Each mid/bass driver features a precise magnet system with an aluminium compensation ring to reduce the effects of inductance changes as the voice coil moves. This advanced motor system minimises intermodulation and distortion, producing cleaner, more accurate sound.

A voice coil beyond this class
The voice coil is wrapped around a high-power epoxy/glass fibre bobbin, which performs significantly better than standard materials at this price point, offering greater power handling, thermal stability, and structural strength.

DIAMOND highs
High frequencies are produced by a 25mm woven polyester dome with a high-loss damping coating, resulting in extended, smooth treble response. The front plate is designed acoustically with a flat profile and minimal waveguide to enhance dispersion and output. The result is clear, natural high frequencies with excellent off-axis performance.

A crossover of style
Wharfedale’s engineers use a sophisticated Linkwitz-Riley crossover design, complete with air-core inductors—components typically found in high-end speakers. The crossover network is finely adjusted for minimal phase shift and smooth integration between drivers.

The magnet structure for the mid/bass driver is modified to address the resistance of these high-quality inductors, ensuring fast, clean bass without compromise.
