I am shopping for speakers crossover parts and need an audiophile mythology check that I haven't been able to get anywhere else on the web. I have a specific question and a more general one.
First the specific question; can I replace a "non-inductive" resistor with one that is not labeled as such for a low-pass crossover network feeding the tweeter? Can I replace this with that? The only difference is that the cheaper part is labeled "non-inductive" and 2W less in power dissipation. My preliminary research has taught me that typical wire wound resistors behave like inductors by creating a magnetic field incidental to the way a resistor is wound that increases with frequency in an AC circuit. This increase in inductance will change the impedance of the resistor as frequency increases. What I want to know is; does this matter at all in an audio application?
The more general question is; are expensive crossover parts worth it? There are pricey heavy-gauge inductors, and expensive capacitors on the market that many believe to make a big difference. If these differences are measurable, are they even audible? Looking for some guidance as someone without an EE background.
