voice coil flux cutting or induced

Clipped · 25th April 2008, 09:05 AM

say you have a dual voice coil speaker....you hook up one coil and you leave the other one disconnected.

then you take a dmm and measure the voltage going through the disconnected coil,

are the voltages going through the disconnected coil a result of induced current from the other coil...OR...is it a result of the coil cutting through the magnetic lines of flux?

or both?

I would guess both. Some soak from the other coil, and then some from the magnetic flux. Would end up acting alot like a guitar pickup in that regards.

ive gotten as high as 90% efficiency at some higher frequencies, this is pretty interesting.
