Designer's Message Uncompromising in design and manufactured with care and precision by Wharfedale engineers, Jade loudspeakers are constructed using the finest materials available. Using traditional craftsmanship combined with the latest advances in acoustic technology, we are able to uphold a Wharfedale tradition of excellence in sonic performance and furniture-quality cabinet making dating back more than seventy years. Wharfedale ensures the very highest standards of manufacture and performance are maintained for the Jade series. To this end each individual drive unit and crossover is...

JADE's cabinets are a work of art, both visually and in the advanced manufacturing techniques employed by Curved cabinet construction incorporates the latest material technology developed by Wharfedale engineers, called Crystalam. This laminated material is formed from a series of critically specified natural wood elements and composites, formulated to reduce panel vibration and acoustic leakage to below the threshold of audibility. Each Crystalam layer is bonded to allow microscopic sliding of one layer upon another, producing a natural damping effect that effectively quells the usual...

Phase Linear Crossov One of the bugbears of hi-fi loudspeaker design is how to crossover effectively from one drive unit to another. Traditionally this has meant long hours spent measuring and testing each loudspeaker system still with a less than perfect For the Jade Series Wharfedale has utilized the most advanced measurement techniques in conjunction with 21st Century computer crossover modeling systems to help achieve a seamless integration between the drive units. First the speaker system is measured in Wharfedale's new anechoic chamber and the mechanical properties of the drive units...

The Jade Aperiodic System The graph above shows a comparison between a typical Reflex system (red) and Jade-7 Aperiodic system (white). The initial transient (tall spike) is followed by resonance which continues for 25mS in the Reflex system. For the Jade system the initial transient is followed by a small overshoot Briggs original idea was to cut thin slots in a shelf inside the speaker leading to the reflex port. The slots acted as an acoustic resistance which controlled the damping of the resonance. For the Jade-5 and Jade-7 floorstanding speakers the Aperiodic system is enabled by...
