In the Thread: Do You Really Know How back EMF Works in Your Audio System?
Post Subject: Good questionPosted by Edgar= on: 2/5/2026
I feel like a lot of speculation would need to happen before getting anywhere near how to translate this into a result for audio. I have no idea, but back EMF is present at every stage of an audio system so its relevant to every component. If I had to make an early speculative bet, I would say transformers are what component could benefit most, maybe followed by loudspeaker motors but who knows? first audio designers would need to embody this information pretty deeply before we are going to see anything remotely like a result for audio.
I'll offer a question for the sake of speculation. Do you know what frequency military aircraft electrical systems operate at? Its not 50/60hz like our grid, it's 400hz. Why? Engineers will tell you it makes for a lighter and more compact system because it allows for the reduction of the size of the iron cores with the increase of frequency. If that were the only factor, why stop at 400hz, why not go much higher in frequency like 4k or more? They definitely can if they wanted to but there is a reason they don't. Why?
I know the answer but do you?
CLUE- there is something else happening in iron cores at 400hz. what do you think it is?Rerurn to Romy the Cat's Site
