Do loudspeaker inductors have audible polarity?
"Wessel Dirksen" wrote ...
I've noticed that this forum has alot of speaker buffs so I figure I'll send this one out. I always tend to have the current flow from inside to outside but to be honest I could never hear the difference in how you orient the inductors. Any ideas or opinions? Technical answer: no. Psychological answer: do YOU hear a difference? :-) |

Wessel Alignment with the earth's magnetic field will have a greater effect. ;-) |

Any ideas or opinions? --- If the inductors are non-toroidal or not wound in cup cores they will exhibit an external magnetic field which can couple into other nearby inductors if the magnetic fields are in alignment. In order to keep this from happening, it is best to separate the inductors physically as far as possible and to keep their magnetic fields at 90° to each other. -- John Fields |

Pardon me if I am drifting off topic here, but I and a collegue of mine recently noticed a quite noticeable deviance from the Z=wL in the impedance of inductors in the HF range. These inductors were made of standard ~0.3mm (I'll have to check this) wires and no iron core (for loudspeaker crossovers). Any explanation to this, apart from skin? http://www.tolvan.com/coil.gif Note that I don't claim big *audible* effects from this in most applications, though. |
