Developed in collaboration with Karl Heinz Fink, one of the most successful speaker designers on the planet, the new Diamond 12.1 nt to be 5 star approved by What Hi Fi 12.1 is a classic bookshelf or stand speaker and is a true mount that embodies the legacy of the Wharfedale Diamond series. This hi-fi speaker features a compact housing with power and detail. Ideal for 2 channel hi-fi systems, it is also suitable for immersive home theater, regardless of room size and application. New Klarity Cone Material is a blend of polypropylene and mica that adds rigidity to prevent bending and supports a lightweight cone with high rigidity, reduced coloring and ultra fast response. The 25mm woven polyester dome tweeter offers open and smooth high frequencies. The back box is sized so that the internal volume completes the drive unit system for the desired sound result. A multi-layer sandwich design supports the distinct characters of the cabinet sound. Even the resonant properties of the glue between the layers were measured to identify the top combination. Basically, they have a great sound. With dimensions of 312 mm x 180 mm x 278 mm (H x W x D), the 12.1 diamond is perfect for bookcase mounting or standing.
