Inductor ga. and phase
« on: 29 Apr 2010, 09:39 pm »
One of my students asked an excellent question that I didn't know the answer for absolute sure.  If one changes the gauge of an inductor in the woofer section of a crossover from 16 ga to 19 ga, we expect a bit more resistance, but does it have a measurable effect on phase?  My suspicion is that it should have little to no effect.  :scratch:

Measurable? Sure.  We can measure way smaller than this.
Audible? Probably not. At least in most common crossover situations.

Phase, no.  Response and efficiency, yes.

Good. This is what I had expected.  A student had worked out his crossover but wanted to bring the bass down just a hair.  I had hoped that using a 19mH instead of the 16 mH inductor that we measured it with would perhaps create a 1 dB drop without changing anything else.
