David Murphy has extensive experience with electro-acoustic modelling and has developed a commercially successful range of acoustic horns, integrating them into 3-way and 4-way cinema screen systems. He holds Australian and US Patents on aspects of acoustic horn design. As an Adelaide based chartered professional engineer, he has been designing loudspeaker systems for Krix Loudspeakers since 1996. He joined Krix after a career in electronic engineering education at the Regency Institute of TAFE (equivalent to a US two year college). Prior to that he was a radio apprentice, radio technician, and gained an Electronic Engineering Degree while at the Philips Hendon Works. He has maintained a continuous interest in audio during his career.

At Krix Loudspeakers he uses COMSOL and SolidWorks extensively, and electro-acoustic measurement systems such as MLSSA, Praxis, EASERA, and the AcoustX D2. He has undertaken technical support visits to South Korea, Japan and China for Krix Loudspeakers in 2004, 2005, 2007, and 2016. More recently he has developed modelling and simulation of the low frequency behavior of custom cinema installations for Krix.

An AES Fellow since 2006, David Murphy has been Vice President of the International Region for four years, a Governor for two years, and is presently a member of the AES Technical Committee TC-AC (Audio for Cinema) and Standards Committees SC-04-08 Measurement and Equalization of Sound Systems in Rooms and SC-04-03 Loudspeaker Modeling and Measurement. He has presented papers or workshops at AES International Conventions in San Francisco, New York, Los Angeles, London, Berlin, Rome, and Australian Regional Conventions in Sydney and Melbourne. He is an active AES member and has been the Chair of the Adelaide Section of the Audio Engineering Society for many years.
