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

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?

Mike Barabasz presents on design challenges for professional active loudspeakers and shows practical examples of what can happen “in the heat of the moment”.
