Driver Performance

As you would expect from a series of this stature, the Diamond 100 is bang up to date in terms of technology and performance. Foremost in the design criteria for Diamond 100 is the ongoing research into loudspeaker driver sound quality. To that end the famous Wharfedale Woven Kevlar cone was put under the technology spotlight and given anew profile based on the research originally carried out for the high-end Jade range.

Incorporated in the low frequency and midrange cones are semi-elliptical ‘break-up’ areas which smooth the response throughout the audible range. In addition each surround is treated to match the cone edge with a unique ‘Diamond Pattern’ moulding. Finally the dust cap is blended and treated to provide a smooth transition and perfect acoustic match to the treble unit.

The treble unit chosen for Diamond 100 came under equal scrutiny during development. As well as selecting a sheer fabric dome and advanced ferrite magnet system, the dome is surrounded by a carefully crafted wave guide that encourages outstanding midrange performance.

Crossover

Combining the drivers is a crossover developed using Wharfedale’s latest ‘Virtual Speaker ’ software. Techniques developed in-house allow the final loudspeaker to be simulated and fully analysed even before a prototype is played for the first time. This simulation accommodates driver performance and cabinet construction, as well as room placement, to make sure that both on-axis and off-axis performance over a wide listening area is fully optimized.
