Precis of Subject:
Pro audio transducer design requires very high power operation with high efficiency, and linear response. All of these goals conflict, optimization and balancing them is critical. Use of sophisticated simulation software including dynamic FEA to work in three domains; magnetic, mechanical, electrical simultaneously is key. When coupled with comprehensive testing using 3D Vibrometry, Klippel analysis, and extended reliability testing significant improvements are possible. Examples including dynamic simulations, full multi domain analysis, and diaphragm vibration are shown. Applications and system measurements showing transducer performance including thermal behaviour are also shown. Results of applying dsp for thermal and mechanical management is shown for an a system using 7kW amplifiers.

Audience:
This talk, and the accompanying listening examples and demonstrations, will benefit live sound engineers of all levels of experience who can get good sound on a daily basis, but would like to understand more about the science behind the issues they are dealing with and the results that they get.
