Speaker voice coil windings

The ability of marketing to carry on about the reduced "skin effect" and how it enhances to sound of the speaker.

I have one in front of me burnt out in a small section not overlying an obvious stress point,ie not lead-in , lead-out or bend. I was just wondering if finer wire could make a VC more vulnerable to failure due to microscopic grit or swarf or something.

Actually, I would think that method would allow a thinner gap. Higher flux density in the gap then.

Probably a good reason nobody else is doing it.

Not sure about description, but seems like the layers would snuggle each other better? Is that what your asking? Square wire is the best for keeping air gaps out or flat edge wound.

As far as i can see under x30 and feel, this coubled up fine wire is round in section. I can see finer wire requires less intrusion into the former to carry the fist axial run , before the first turn proper. Also able to make a tighter bend perhaps with less localised stressing than the single wire option.
