David Murphy is an Adelaide based chartered professional engineer who has been designing loudspeaker systems for Krix Loudspeakers since 1996, joining 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 EE Degree while at the Philips Hendon Works. He has maintained a continuous interest in high quality sound reproduction during his career as a technician, professional engineer, lecturer, middle and senior manager, and professional engineer.

At Krix Loudspeakers he uses COMSOL Finite Element Analysis and Solid Works 3D CAD extensively, other simulation software such as MathCad, LEAP, MatLab, and electro-acoustic measurement systems such as MLSSA, Praxis, the AcoustX D2 and EASERA. He has developed a commercially successful range of acoustic horns, and integrated them into 3-way and 4-way cinema screen systems, and holds Australian and US Patents on aspects of acoustic horn design. He has undertaken technical support visits to South Korea and Japan for Krix Loudspeakers in 2004, 2005 and 2007 and China in 2017 as well as for many Australian cinemas, providing advice on the commissioning, installation, and equalization of 3-way and 4-way cinema screen systems.

He has been the Chair of the Adelaide Section of the Audio Engineering Society for nearly 30 years. The Section provides a forum for the local audio industry and selected interest groups and promotes education and information about all sectors of the industry. He has presented papers at AES International Conventions in San Francisco, Copenhagen, New York, London, Berlin, Rome, and AES Australian Regional Conventions and SMPTE in Sydney and Melbourne. He has made numerous technical presentations to local meetings of the AES, IREE and IE Australia. An AES Fellow since 2006, he has been VP International twice and a Governor of the AES. He is currently a member of three Board of Governors Committees, SC-04-03 and SC-04-08, and the AES TC on Audio for Cinema.
