FOREWORD Britain has long been recognised throughout the world as being the home of loudspeaker technology in terms of innovation and quality. This reputation has been built up over many years by some of the world's most famous loudspeaker manufacturers. Wharfedale, established over eighty years ago, has always been at the forefront of maintaining this reputation. Briggs interest in quality sound reproduction stemmed from his great love of music; he was himself an adept pianist, and had a keen ear for the makings of a good loudspeaker. Indeed two of the first drive units he assembled in the...

Introduction Wharfedale’s Diamond series has a long history of achievement. The first Diamond was born in 1982 - in a rear-ported cabinet of just over 5 litres were fitted a 19mm dome tweeter and 120mm long throw, polypropylene bass/mid driver. The crossover was simple but highly effective. This product took the industry by storm. The small cabinet and impeccable stereo image meant the Diamond quickly became a best-seller and a permanent fixture in the Wharfedale product range. Since then every new range of Wharfedale Diamond Series has been a best seller.

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 a new 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...

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 optimiz

Cabinet Design Naturally cabinet design was not forgotten in amongst all the other technology. Rectilinear cabinet shapes were chosen to maximize the internal volume and provide the deepest, most extended bass response. Again the research from the highend Jade series was incorporated to elicit the latest advance in loudspeaker reflex loading – the SlotLoaded Distributed Port. Exiting at the base of the speaker cabinet, the reflex port is loaded by a slot created by the plinth. This equalises the air pressure to mimic that inside the cabinet allowing smooth transition between the pressure...

The Real Test That doesn’t mean that Diamond 100 is purely a computer design, clever though that might be. This ‘Virtual Speaker’ is simply a tool that allows the Wharfedale engineers to explore all facets of the loudspeaker ’s performance before starting listening tests. 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...
