Audio Engineering Society – Melbourne Section

Notice of Annual General Meeting

The Annual General Meeting of the Melbourne Section of the AES will be held on
Monday September 14^th 2015 at 7:30pm at The SAE Institute – Lecture Theatre, 235 Normanby Rd South Melbourne (directions below)

The short AGM will be followed by a presentation by Michail Barabasz on the topic

Anatomy of the Loudspeaker Driver

Michail’s wide-ranging talk will cover the full range of considerations affecting the successful design of loudspeaker systems. They will include topics like the listening room (and its effect on loudspeaker reproduction), loudspeaker component parts, post Plessey Rola (what has changed in the past 40 years), speaker testing (why measure, what should be measured, and QA testing), how pro-audio, monitor and HiFi speakers differ, and design software.

The next meeting of the AES Melbourne Section will be on Monday 10^th August at 7:30pm
at The SAE Institute Lecture Theatre, 235 Normanby Rd South  Melbourne.

Hugh Dean of Aspen Amplifiers (http://www.aksaonline.com) will present on the topic

Designing Practical High End Audio Amplifiers

Hugh will describe the history of his AKSA amplifier design, giving detailed information and methodologies. He will also highlight the importance of establishing an appropriate distortion profile to provide a more realistic merit indicator than a simple THD% figure.

He will challenge the efficacy of the “Vanishingly-small THD Figure” specification approach, offering a different approach to the distortion issue for amplifiers designed to reproduce music.

This should be a most interesting, informative, and thought-provoking presentation.
