Title: One question on the loudspeaker
Post by dandelion on Feb 24^th, 2008, 9:58pm

Hi
I am designing the class-d audio amplifier. I have a question on the loadspeakers. I see some papers assert as below:
.............
Loudspeakers are often modeled as resistors but in reality they are highly reactive. A typical 8 loudspeaker can have impedance minima as low as 4 and also behave nonlinearly.
.............

I wonder if the loudspeaker is 4 Ohm load, then can we think the minimum impedance is as low as to 2 Ohm? Can we have this conclusion?

Any loudspeaker expert shed some light on it?

Thanks
