December 2021 Meeting Notice: Michail Barabasz – Loudspeaker Power Ratings

Meeting Notice

The next online meeting of the AES Melbourne Section will be on Monday 13th December 2021 at 7:30pm.

Michail Barabasz, of loudspeaker maker Lorantz Audio will present on the topic of:

Loudspeaker Power Ratings

Modern class D amplifiers are capable of kilowatts of drive and care little for the load impedance. Can loudspeaker voice coils and suspensions handle this?

Meeting Report: June 2019 MESS

On a cold and damp Melbourne winter evening 13 brave souls gathered at the Melbourne Electronic Sound Studio in North Melbourne to learn more about MESS, and its unique collection of (primarily) analogue synthesisers.

Our host for the night was one of the founders, Byron Scullin.

After introducing himself, and giving a potted history of his career and experiences to date, Byron took us through the role of MESS as a not-for-profit organization founded by Robin Fox and himself. He described it as charity devoted to the housing of a collection of functional classic electronic instruments for musicians to experience creating analog synth music in a workshop environment using hardware, as opposed to today’s software recreations.
