Wharfedale Diamond 250 Stereo Floorstanding SpeakersWharfedale
The Diamond 250 is a 3 way Floor Standing speaker featuring DUAL 8 inch kevlar woofers, 5 inch kevlar mid, 1 inch soft dome tweeter.
The Diamond 200 series boasts the latest in hi-fi technology to produce a thoroughly enjoyable listening experience. Foremost in the design criteria for Diamond 200 is the ongoing research into loudspeaker driver sound quality. The Diamond Series utilises our famous woven Kevlar® cone drawing influence from the flagship Jade Series. Semi-elliptical ‘break-up’ areas on the Kevlar® woofer smooth the response through the audible range and the cone edges are treated with a unique diamond moulding.
Cabinet walls and internal bracing developed using Wharfedale’s latest ‘Virtual Speaker ’ software, with the help of Delayed Cumulative Spectral Analysis that ruthlessly reveals panel colouration in all its forms. Using this technique Wharfedale engineers updated the cabinet combining layers of particle board and MDF bonded in a unique structure to damp annoying High-Q resonances and block internal sound leakage. The effect is that the ‘noise’ from cabinet walls is buried more than 35dB below the driver output. The same computer modeling also assists in fine tuning the crossover while ensuring the speaker projects both on and off-axis for an enjoyable, room-filling experience..
In the final evaluation weeks are spent fine tuning the acoustic performance using a wide variety of music in Wharfedale’s five listening rooms, each of which mimics the kind of domestic environments the Diamond Series are likely to be used in. Only when the acoustic tests are deemed truly satisfying are the loudspeaker designs signed-off for production, ensuring that each speaker model fulfils its eventual owner’s dreams of musically enjoyable reproduction from Britain’s Most Famous Loudspeakers.
