UK: THX’s chief scientist, Laurie Fincham, will present a paper on Controllable Line Arrays to the AES UK Section in London next week. As part of his presentation, Fincham – widely regarded as a pioneer of computer modelling in loudspeaker design – will discuss theoretical and practical design criteria for two-dimensional line arrays with controllable directivity.
Other issues due to be covered in the session – which will be held in the Conference Room at the Royal Academy of Engineering on February 13th – include the provision of sufficient volume velocity to achieve acceptable bass output without losing control of directivity. Fincham is also planning to demonstrate an array that is capable of real-time changes in both directivity and beam direction with multiple beam overlays.
For Joe Bull – managing director of SADiE UK and a member of the AES’ UK chapter – the lecture represents another welcome opportunity to stress the importance of “high quality audio reproduction. If it’s worth capturing or amplifying, it’s worth making it as accurate as possible.”
Fincham brings to the session a wealth of experience in loudspeaker design, acquired during a career spanning more than four decades. Positions with Goodmans Loudspeakers and Celestion were followed by a celebrated 25-year stint as the technical director of KEF Electronics, during which time he co-developed the first FFT-based measurement system. Moving to the US in 1993, Fincham went to work for Infinity Systems before joining THX in 1998.
The lecture is free to all and will begin at 7pm. Complementary refreshments are available from 6.30pm.
