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 Electronic Engineering Degree while at the Philips Hendon Works. He has maintained a continuous interest in audio during his career as a technician, professional engineer, lecturer, middle and senior manager, and professional engineer.
At Krix Loudspeakers he uses COMSOL and SolidWorks extensively, and electro-acoustic measurement systems such as MLSSA, Praxis, EASERA, and the AcoustX D2.
