Wideband Compression Driver Design Seminar

17 November 2015
Building 13, Room 3017

Event details


Compression drivers are widely used in high output loudspeaker systems due to their efficiency, which can be as much as ten times greater than a direct-radiating cone driver. This high efficiency is achieved by channelling the sound radiated by the diaphragm through a number of small channels to the throat of a horn. In addition, for maximum output, the diaphragm should be as large as possible. This complex arrangement is prone to both acoustical and mechanical resonance, and the overall performance is highly dependent upon the geometry of the diaphragm and channels. In this seminar we take a closer look at these devices and recent developments that permit the use of larger diaphragms.

Speaker information

Jack Oclee-Brown , KEF Audio. Jack Oclee-Brown received an MEng degree in acoustical engineering from the Institute of Sound and Vibration Research (ISVR), University of Southampton, UK, in 2004. Since then he has been with KEF Audio, where he now holds the position of Head of Acoustics. In 2012 he received his PhD from the ISVR for a thesis on the acoustic design of compression driver phase plugs. He is interested in all aspects of loudspeaker engineering and design. His work for KEF is currently focused on loudspeaker modelling, the development of software tools to aid loudspeaker design, and transducer design. Dr. Oclee-Brown is a member of the Audio Engineering Society
