Extract from interview with the eminent physicist Professor Ian Ward with whom Wilson Benesch collaborated during the Bishop Project in 1999.
This film has been extracted from a long interview with the physicist and member of the Royal Society Professor Ian Ward that was carried out during the summer of 2009.
Professor Ward explains the fundamental properties of the material Isotactic Polypropylene, that he and his team developed during the last decade of the 20th century. One of the first if not the first application of this material was for loudspeaker cones.
Isotactic Polypropylene is five times stiffer than a conventional polypropylene and as Professor Ward explains, it is extremely effective in its ability to damp resonant energy at the molecular level. The tenacious strength of the material required extremely precise processing that was collaboratively developed as part of the Bishop Project.
Wilson Benesch is the only audio company in the world to have undertaken a number of Government / European supported research and development projects. This material was introduced by Wilson Benesch in its advanced Tactic Dynamic Drive unit design in 1999. The material has recently been recognised by other audio companies. The drive units supplied to Sonus Faber now see this material being exploited in the recent designs that were released in 2010.
