Posted by on 2021/11/22 No comments

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

…and other myths.

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?
Dedicated amplifier/loudspeaker combinations in active boxes can have sophisticated protection programming.
How effective can this be?
How should the standards for loudspeaker testing and power ratings tackle this?

The next online meeting of the AES Melbourne Section will be on Monday 11th October 2021 at 7:30pm (Australian Eastern Daylight Saving Time UTC+11).

Joe Hayes, Inventor and CTO of Vastigo Ltd will describe his DaS AuReality technology in a talk titled:

From Stradivarius to Speaker

technology for improvements in sound delivery and room acoustics treatment.

We are familiar with a well-designed concert hall having clarity of performance without hard echoes and a balanced enveloping sound field.
We seek to capture this in our recording and listening experiences but we often must put up with less-than-ideal acoustic environments.

And what if the recreated sound field did not detract from the initially arriving direct sound but could actually mask and improve the inevitable echoes and reflections of the typical less than the ideal listening environment?
